Vaccines are one of the greatest public health success stories in history

They help protect against more than 20 potentially life-threatening diseases.

We recognize and support the many global health stakeholders, including the World Health Organization, for their efforts in raising awareness about the importance of vaccination and helping prevent infectious diseases around the world.

“Immunization is a global health and development success story…helping people of all ages live longer, healthier lives…It’s also one of the best health investments money can buy. Vaccines are also critical to the prevention and control of infectious disease outbreaks [and] underpin global health security…”

  • World Health Organization, 2023

Broader vaccination coverage along with other public health measures have eradicated smallpox and significantly decreased the incidence of other vaccine-preventable diseases.

Vaccine equity is a global challenge

The COVID-19 pandemic triggered unprecedented disruptions to vaccination programs around the world, resulting in the largest sustained decline in childhood vaccination rates in approximately 30 years.  

The pandemic also revealed underlying health inequities and reminded us of the importance of preserving trust in and advancing equitable access to vaccines.

More than 1.5 million people worldwide die from vaccine-preventable diseases each year. In 2018, ~700,000 children under age 5 were estimated to have died from vaccine-preventable diseases, and a staggering 99% of these children had lived in low- and middle-income countries.

Recovering vaccination rates together

Now, more than ever, we have an opportunity to reimagine the role we all can play.

At MSD, our broad portfolio of vaccines helps prevent diseases affecting individuals around the world and across all stages of life, from infancy through older adulthood.

But, we can’t be successful alone. That’s why we are working with a variety of stakeholders to help recover vaccination rates impacted by the pandemic, build trust in vaccination and enable equitable global access to vaccination services for everyone who can benefit from them. Our approach includes global, national and local engagement.

We’re also encouraging individuals to speak with their health care provider about vaccines that may be recommended for them or their families. Through our work in vaccines, we are committed to helping protect people today and for generations to come.

MSD and its legacy companies have a 130+ year history of innovation and commitment to helping prevent disease by discovering, developing, supplying and delivering vaccines.

To keep pace with the ever-evolving disease landscape, we go where the need is to find new ways to address complex public health problems. We continue to invest in groundbreaking research and breakthrough technologies to help protect against potentially life-altering vaccine-preventable diseases.

Individualized neoantigen therapies: exploring one medicine for one patient

Scientists are researching new ways to help train the immune system to fight cancer

Over the past decade, immunotherapy has transformed our understanding of how the immune system can be used to help fight some types of cancer. However, for the last 50 years, scientists have been researching how we could potentially use vaccines to treat cancer — another investigational approach to harness the immune system to help recognize and destroy cancer cells — with little success.

Now we’re looking at a potential therapy that is building upon the learnings of immunotherapy trials from the past and incorporating that into an individualized cancer approach that’s specific to a patient’s own tumor. Researchers are currently exploring the potential of individualized neoantigen therapies to help fight cancer.

Cancer research is becoming more personalized

Cancer is a result of the body’s own cells undergoing mutations which create abnormal proteins in cancer cells, known as neoantigens, that are not usually seen in normal cells. These mutations are unique to each person’s tumor, so that’s one of the reasons why patients who have been diagnosed with the same type of cancer and who have received the same type of treatment may have different responses.

As the treatment of cancer continues to evolve and advance, researchers are focusing on more individualized approaches. This includes a new area of research into individualized neoantigen therapies that use information from a person’s tumor biopsy sample to help develop a therapy unique to their tumor’s mutations.

MSD's Dr. Jane Healy

“This area of research has really captured our imagination of what’s possible in the development of cancer therapeutics.”

  • Dr. Jane Healy
    Vice president and head of oncology early development at MSD Research Laboratories

In collaboration with Moderna, we’re studying this area of research in an effort to advance more individualized approaches to help improve outcomes for people living with cancer.

What is melanoma?

Melanoma is a serious form of skin cancer. Characterized by the uncontrolled growth of pigment-producing cells, melanoma accounts for approximately 1.7% of new cancer cases worldwide.

Melanoma can occur anywhere on the skin, including areas without sun exposure, but it’s more likely to start in certain locations, like the face and neck, legs (most common in women), and chest and back (most common in men).

Melanoma common sites

The risk of melanoma generally increases with age and incidence is greater among older populations. Melanoma is not uncommon, even among patients younger than 30 years, and is one of the most common cancers in young adults, especially young women.

In most areas of the world, melanoma diagnosis rates have been rising over the past few decades

In 2020, it was estimated that there were more than
324,000

new melanoma cases worldwide

Signs of cancerous moles

A new spot on the skin or a spot that is changing in size, shape or color, or one that looks different, is an important warning sign of melanoma and should be checked by a doctor. The ABCDE rule outlines the characteristics of moles that may be melanoma and is helpful guidance for monitoring skin changes:

Illustration A is for Asymmetry

A is for Asymmetry

One half of a mole or birthmark does not match the other.

Illustration B is for Border

B is for Border

The edges of the mole are irregular, ragged, notched or blurred.

Illustration C is for Color

C is for Color

The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white or blue.

D is for Diameter

The spot is more than 6 millimeters across (about 1/4 inch – the size of a pencil eraser), although melanomas can sometimes be smaller than this.

E is for Evolving

The mole is changing in size, shape or color.

Any of these warning signs should be discussed with a doctor, especially if you feel you are at risk for melanoma.

Risk factors of melanoma

There are many risk factors and causes of melanoma, including:

  • Ultraviolet light on your skin, such as from the sun or a tanning bed (the most common risk factor for melanoma).
  • Age — melanoma is more common in older people, but younger people are also at risk. Melanoma is one of the most common cancers in people younger than 30 years (especially among women).
  • Moles — having atypical moles, many moles and/or large moles.
  • Personal or family history — melanoma can be genetic and having a relative with melanoma can increase your risk.
  • Fair skin or a fair complexion, a lot of freckles and/or light-colored hair and/or eyes.

Ways to lower your risk of melanoma

Melanoma can’t be entirely prevented, but there are ways to lower your risk. The number one way to lower risk is to protect against UV rays, which damage the DNA of skin cells and impact the genes that control skin cell growth. The top source of UV rays is the sun. That’s why it’s important to practice sun safety every time you go outside, even on cloudy days when UV rays can still shine through. Here are a few ways to protect yourself:

Seek shade icon
Seek shade

UV exposure is greatest between the hours of 10 a.m. and 4 p.m. If you need to be outside during these hours, seek shade — under a tree, an umbrella or an awning.

sunhat icon
Wear a hat

Try to find a hat with a wide brim — at least 2 or 3 inches wide — to protect your face, top of the head, ears and neck.

cover up icon
Cover up

Choose clothing with a tight knit or weave, and avoid shirts that you can see through. Remember, if light is getting through, then UV rays are too.

sunscreen icon
Use sunscreen

For extended outdoor activity, use a water-resistant, broad spectrum sunscreen with an SPF of 30 or higher.

sunglasses icon
Wear sunglasses

Protect your eyes and the sensitive skin around them. Pick a pair of sunglasses that will block as close to 100% of both UVA and UVB rays as possible.

How early detection of kidney cancer can help save lives

An oncologist and a patient advocate discuss the challenges of renal cell carcinoma and their hopes for the future of cancer care

When Liz Leff, an otherwise healthy woman in her 30s, went in for her annual checkup eight years ago, cancer was the last thing on her mind. But that routine checkup set her on a path with renal cell carcinoma (RCC), the most common type of kidney cancer.

The testing that led to Leff’s early kidney cancer diagnosis

Liz Leff and her daughter
Leff and her daughter

“My primary care physician saw microscopic traces of blood in my urine — which I was told isn’t uncommon — and suggested a follow-up appointment with a urologist,” she said. “I was reluctant to go in for testing for something that seemed insignificant, but my doctor pushed me to have it checked. I’m so glad I did. A renal ultrasound showed a tumor on my kidney.”

The World Health Organization estimated that there were approximately 431,000 new diagnoses of kidney cancer, which includes RCC, in 2020 across the globe. RCC occurs when cancerous, or malignant, cells form in tiny tubes in the kidneys, known as tubules.

One of the difficulties around early diagnosis is that unlike breast or cervical cancers, there’s not a preventive care screening test for RCC. Kidney cancer is often found during abdominal imaging tests for other complaints,” said Dr. Rodolfo Perini, an associate vice president who leads the RCC clinical team at MSD Research Laboratories.

Leff’s experience is not typical, as at the time of diagnosis she was young. Additionally, she was not experiencing any symptoms at the time of her diagnosis.

“For most people, common symptoms — like persistent pain in your side or loss of appetite — can be vague and are often brushed off. By the time they become more severe, disease may have spread,” said Dr. Perini. “That’s why it’s so important to listen to your body and share anything you’re experiencing with your doctor. Early detection is associated with better outcomes.”

Kidney cancer causes and care

Risk factors for renal cell carcinoma include smoking, being overweight or obese, having high blood pressure, having a family history, and having a history of exposure to environmental toxins. The risk of kidney cancer may also be greater for Black men and for people over the age of 45.

“The research landscape has changed, and we’ve seen improvements in the care of kidney cancer over the years, but it’s not good enough,” said Dr. Perini.

"We still have work ahead, but with the progress that’s been made, there’s reason to be excited for the future.”

— Dr. Rodolfo Perini

Life as an advocate after experiencing kidney cancer

Leff is also hopeful about the future of care in kidney cancer. Following successful treatment, she joined the National Kidney Foundation, where she draws on her own experiences to better advocate for others living with kidney cancer.

“When I first heard the word ‘cancer,’ I was terrified. I felt like I was in this alone with no place to go. I don’t want others to go through what I went through,” Leff said. “From when I was diagnosed to now, there’s a lot more information and support available.”

“My ultimate hope is that continued research, plus more resources and education for patients, may help lead to earlier diagnoses and better outcomes for more people.”

Josette Gbemudu is motivated to ensure everyone has the chance to be as healthy as possible.

As an executive director of health equity and social determinants of health, Gbemudu draws on her health policy and public health backgrounds — and her strong moral compass and lived experience.

“I grew up in Nigeria and witnessed the health care and public health system crumble,” she said. “Populations that were already underserved faced even further barriers to care.”

She takes pride in giving a voice to those who may not traditionally have had a seat at the table.

“The work we do is very exciting and important — it’s challenging, it’s not easy, there’s a lot you have to do to navigate — but it’s all fulfilling,” she said.

A ‘first mover’

Gbemudu was the first nominee from our company to participate in the Aspen Institute’s First Movers Fellowship program.

The program equips leaders across industries to be intrapreneurs, meaning they work to advance societal value while also positioning their companies for sustained success.

“The global community is increasingly asking, and frankly, requiring, organizations to have a clear position around what they are doing to tackle the world’s most pressing and imminent challenges."

— Josette Gbemudu

“This fellowship has provided a tremendous opportunity to home in on what it takes to be a corporate social intrapreneur, and how to incorporate that intrapreneurial drive and mentality into my day-to-day,” Gbemudu said.

At the nexus of health equity

Fellows are challenged to lead change and create new opportunities within their business to help redefine how business is done and how success is measured. At our company, Gbemudu and her colleagues are developing and implementing company-wide strategies to help close gaps in care for underserved populations.

“It’s fantastic to be at the nexus of the efforts to embed a health equity mindset across our core business strategies and functions,” Gbemudu said. “Big problems won’t be solved overnight. But historically, we’ve risen to the challenge in addressing a lot of pressing public health issues. It’s nterwoven into our DNA.”

VIDEO: Living with pulmonary arterial hypertension

One woman’s story shows the power of knowledge and support for patients with pulmonary arterial hypertension (PAH)

February 13, 2023

Share this article

.st0{fill:#00857C;}

article hero thumbnail

Pulmonary arterial hypertension (PAH) entered Colleen’s life unexpectedly. She was 35 when she noticed she became short of breath easily. She thought it was due to the weight she gained during her recent pregnancy. A year later, Colleen lost the weight but was still gasping for breath after climbing a few flights of stairs. Colleen wasn’t only feeling fatigued; she was worried. She’d later learn these were symptoms of PAH.

Colleen was first diagnosed with asthma, but her condition continued to worsen. She searched for an answer while daily tasks became more difficult. It took two and a half years for Colleen to be referred to a cardiologist who properly diagnosed her with PAH, one of the five different types of a broader condition called pulmonary hypertension (PH).

What is pulmonary arterial hypertension (PAH)?

PAH is a rare and life-threatening blood vessel disorder that worsens over time. PAH has similar symptoms to other common lung diseases, such as asthma, which can make it difficult to diagnose.

In PAH, the pulmonary arteries — the blood vessels that carry blood from the right side of the heart into the lungs — become thickened and narrowed. This blocks blood from flowing through the lungs, which then raises blood pressure in the lungs. As a result, the right side of the heart must work harder to pump blood into the lungs to keep the body functioning properly.

Recognizing the signs and symptoms of PAH

The exact cause of PAH is unknown, and most people with PAH have no known family history of the disease. People may not notice any early-stage symptoms of PAH, but as the disease progresses, they may experience common symptoms, such as increased shortness of breath, fatigue, edema (swelling of the feet, legs and, eventually, the abdomen and neck), dizziness and fainting spells, chest pain, and heart palpitations (racing or pounding).

People with PAH may notice that their lips and fingers turn blue. PAH can hinder a person’s physical abilities and impact everyday tasks.

“Living with pulmonary arterial hypertension isn’t easy.”

“I had to purchase a scooter to do outside activities with my children. I couldn’t perform basic functions for myself and my family or make it to the sidelines of a baseball field to watch my son play. I was truly relegated to living on the sidelines myself. But through it all, I’ve never given up,” said Colleen.

Raising awareness for PAH

In addition to working with her doctor, Colleen found comfort through her support system. Since her diagnosis, Colleen has dedicated her life to raising awareness of PAH and helping others living with the disease. “It’s important for patients and the community to have knowledge and encourage each other. Whatever we can do to lift the community and spread awareness of this devastating disease is appreciated,” she added.

A diverse workforce is not only fundamental to our company’s future success, but it’s also a part of our rich history. Taking a look back in time, we highlight the contributions of Black leaders and company milestones that have made an impact on diversity and innovation in our past, present and future.

A long history of Black inventors and innovators

01.

Susan Jenkins paved the way for black women in science at MSD

Susan Jenkins began a long career at MSD in 1957 when she joined MSD Research Laboratories (MRL) as one of its first female Black chemists. She was part of the team that first synthesized ribonuclease. Later, she joined our company’s corporate equal employment affairs department and served as a black university liaison. By the end of her career here, Susan was senior vice president of human resources and was emblematic of how important having Black women leaders in science was to creating an inclusive work environment.

Susan returned to our company almost 50 years later to attend the presentation of the Citation for Chemical Breakthrough award from the American Chemical Society (ACS) division of the History of Chemistry. The Citation for Chemical Breakthrough was awarded in honor of the series of five articles published in the Journal of the American Chemical Society describing the first total synthesis of an enzyme. These articles were authored by Dr. Ralph Hirschmann and his colleagues in 1969, one of whom was Susan.

William Bowers’ advocacy for civil rights at work and across the country

MSD alumni include numerous prominent Black civil rights leaders, including William “Bill” Bowers. Bill joined our company in 1951 as a technician, a position he held until 1969 when he received a bachelor of science degree in business management from Rutgers University. He earned his degree with assistance from our company’s educational grant program while balancing his full-time job, four children and many leadership positions in his community, including vice president of the Westfield Community Development Corporation.

Bill retired from a project management position at our company in 1993. He was a vocal proponent for civil rights nationally and within our company, having participated in the 1963 March on Washington. He was a co-founder of Black Employees at MSD (BEAM), which later became MSD’s Black Employees Network (BEN) and is known today as LEAD — MSD’s League of Employees of African Descent, which celebrated its 50th anniversary in 2020.

Baseball star Jimmy Dean found a second career at MSD

During the late 1940s, Negro League baseball featured a star pitcher named Jimmy Dean. Famous for his sinker-ball, Jimmy pitched for the Philadelphia Stars facing legends like Jackie Robinson and Hank Aaron.

After the integration of Major League Baseball started to draw athletes and fans away from the Negro Leagues, Jimmy returned to school and began working for MSD. Jimmy traveled extensively, put three sons through college and after 33 years, he retired from his position as a technical analyst in 1990.

Our commitment to diversity in science careers

01.

Investing in future science leaders

In 1968, MSD began sponsoring the Technical Training Program (TTP), a non-profit organization in Newark, New Jersey, which offered classes and on-the-job laboratory experience for students interested in pharmaceutical industry careers. TTP primarily targeted young people from educationally and economically disadvantaged backgrounds. Among TTP’s first graduating class were William “Gary” Mickle and Darrell Harris who became laboratory technicians in MRL. Gary would ultimately work in MRL for over 35 years.

02.

Prioritizing equal opportunities for Black and minority employees

In 1968, MSD appointed Lawrence “Larry” Branch vice president of personnel relations, responsible for coordinating and recommending programs for employment, training, and promotion of persons from all minority groups. This new position marked the beginnings of MSD’s Office of Equal Employment Affairs — one of the first in the country to prioritize equity for black employees, among many other initiatives. Over the years, the Office of Equal Employment Affairs continued to evolve, establishing companywide programming to address complex workplace issues such racism, sexism and other barriers to equality. The programming was so successful it served as a model to other corporations, government organizations and community groups.

03.

MSD celebrated for innovative diversity programs that support our Black employees

During the 1980s, MSD was recognized for its leadership in equal opportunity employment. As national politics surrounding affirmative action grew to be more complex, we maintained our focus on welcoming and supporting diverse employees. The 1983 book “The Hundred Best Companies to Work for in America” listed our company as  No. 15, specifically citing our diversity initiatives.

That same year our company’s commitment to equal opportunity earned recognition from the United States Department of Labor with its Exemplary Voluntary Efforts Award. Then in 1989, we were included on Black Enterprise magazine’s first-ever list of the 50 Best Places for Blacks to Work. Ever since, we have maintained a consistent presence on lists praising corporate diversity published by Black Enterprise, Forbes and more.

Women in science? Absolutely

Strong career paths and cutting-edge science draw more women scientists — like chemists and engineers — to our small molecule process R&D team

Women scientists have historically been underrepresented in the field of process research and development — the space between drug discovery and manufacturing.  However, over the past seven years, the percentage of women on our company’s small molecule process research & development (SM PR&D) team has nearly doubled and continues to grow.

“This progress is important because it reflects our mindset that diversity and inclusion fuel creativity and innovation.”

  • Jamie McCabe Dunn
    Director, process chemistry
Jamie McCabe Dunn

“Our group today looks dramatically different than it did when I first started 14 years ago because we’ve taken steps to build more diverse teams,” said McCabe Dunn.

And, women chemists and engineers are vital to our success.

“While we’ve come a long way in the last decade, achieving greater gender equity must continue to be a priority for all leaders,” said Kevin Campos, vice president.

One successful approach has been for women leaders to take more active roles in recruiting talent. This allows  for greater relationship building among female candidates applying for jobs in science fields and provides a vision for growth opportunities at our company.

“We’re also expanding relationships with more academic institutions and casting a wider net to find excellent talent,” said McCabe Dunn. “As more women join the company and see the strong career paths open to them, we expect to see even greater diversity.”

A woman chemical engineer in a male-dominated field

Eighteen years ago, when Marguerite Mohan joined MSD, she was one of a small group of women scientists on the team. Although not different from what she experienced academically, she recalls being asked whether she thought this environment would limit her.

“I had no concerns being in the gender minority…I knew I was here because of my ability.”

  • Marguerite Mohan
    Executive director, chemical engineering, SM PR&D
Marguerite Mohan

“I loved being a chemical engineer and wanted to apply my skills where I’d make an impact on people’s lives. The interface of research and manufacturing was a great place to start,” said Mohan.

Tasked with developing and scaling up processes to safely, innovatively and robustly produce drug candidates for clinical trials and commercial use — these teams deliver for patients through cutting-edge science.  They challenge the status-quo and try new things. That’s also how they recognize and develop talent.

“We’re committed to making sure everyone’s voice is heard and respected. This has allowed women to frame what technical growth looks like from our point of view, bringing diversity of thought to the problem-solving and leadership table,” said Mohan. “By challenging the status quo, we’re creating stronger, more innovative teams filled with unique scientific talent.” 

A new generation of women scientists

Niki Patel and Cindy Hong joined our company within the past six years — both drawn, in part, to our reputation as a scientific leader committed to improving human health.

“I was very aware of the team’s novel and innovative science through publications in high-profile, peer-reviewed journals and presentations at conferences. This was a place where I wanted to do great science,” said Patel, associate principal scientist. 

It was also a place where both Patel and Hong knew they’d fit in.

“As a female graduate student, I was definitely outnumbered. But, when I interviewed here, I saw such diversity on the teams – including at leadership levels.”

  • Cindy Hong
    Associate principal scientist
Cindy Hong a scientist at MSD

“I knew this environment was right for me,” said Hong. “I’ve worked with great female and male leaders since joining the company and been exposed to many different areas of expertise. I see real opportunities for growth.”

Women empowering other women in science

Strong networks and outreach are important to not only maintain a pipeline to potential female scientist candidates but also retain and promote those already on the team. They can include things like collaborative communities, mentor programs, publishing papers or grassroots efforts.

“We’re empowered to take steps to support women in this field.”

  • Niki Patel
    Associate principal scientist
Niki Patel

“For example, I’ve helped organize forums to discuss topics on diversity and inclusion and participated in career panels geared toward supporting women and underrepresented groups in the field,” said Patel.

Sometimes, that support might simply be a quick note of recognition.

 “I try to acknowledge micro-accomplishments in the moment — things that seem small but are important to that person,’” said Mohan. “It’s a simple, personal way to show someone they — and their work — matter.”

In addition to kudos from colleagues, many of our female scientists have been recognized externally. In the last three years, 12 women in the department have been honored with individual awards or as key contributors in team awards. These awards include the ACS Division of Organic Chemistry Early Career Investigator, ACS WCC Rising Star, ACS Fellow, Heroes of Chemistry, the Edison Patent Award, the ACS Award for Computers in Chemistry and Pharma, and an HBA Rising Star.

“We have a high success rate,” said McCabe Dunn. “Ninety-two percent of the women we’ve nominated or renominated for individual awards have won.”

Can women have a successful career in science?  Absolutely. As Mohan says, “Know your core, be true to it and value what makes you a unique asset.”

Testing experiments in a lab can be a lot like raising kids. Sometimes your molecules do what you want them to do, and sometimes they don’t. But it’s a challenge Denarra Simmons, a senior scientist at MSD and a mother of two, is always up for.

“You’re constantly trying to find other medicines because all medicines don’t work the same way for all people,” Simmons said.

“You spend the long nights thinking about experiments, how to make things better, how to move things faster to help more people.”

— Denarra Simmons

Denarra Simmons working in a lab

Simmons has been curious about how and why things work for most of her life. As a young child, she peppered her family with questions, trying to understand the “why” behind anything and everything. But it wasn’t until a man in a lab coat came to her grade school to talk about his career that she realized what her true passion was.

“He wrote an equation on the board and was talking about how people made medicines, and I thought that was fascinating,” Simmons said. “But the thing that really drew my attention was how excited he was when he was explaining what he did. I wanted to do something that I would love that much and over time, I realized that for me, it was science and helping people.”

For 12 years, Simmons has funneled that passion into her research at MSD. Simmons works in drug development to test the efficacy and safety of our biologic medicines used for investigational new drug (IND) enabling studies.

“Working in the lab is my favorite part of my job — and getting good data."

Denarra and her family

Some days in the lab may be more successful than others, and Simmons uses it all to show her children what it takes to be a scientist. “Good days are celebrated, and the tricky days, we keep working towards improving,” she said.

Simmons also feels strongly about teaching her children that there’s more to life than work.

“I’m always thinking about the experiments, but when I’m home with the children, I really try to give them the attention and time they need,” she said.

But once her daughter and son finish their homework and head to bed, Simmons finds herself thinking about her next set of experiments.

“When you find out a medicine you worked on has helped so many people, you feel really special and you know all the work has been worthwhile,” she said. “And that’s why you’re doing what you do: you’re making a difference in society.”
