In the lab: Harpur alumna helps develop Pfizer vaccine

When your turn comes to roll up your sleeve for the coronavirus vaccine, take a moment to consider the countless hours that went into its creation. Teams of scientists worked around the clock to analyze the virus, find ways to provoke the immune systemâs response, and test its efficacy and safety.
Among them is Harpur College alumna Darryl Melissa Charles, a vaccine research and development scientist at Pfizer working in the assay development group. In layman terms, she and her colleagues measure antibody responses to the vaccine in a sample of blood serum.
âIt makes me really excited when everyone tells me that âI got the Pfizer vaccine.â Itâs a sense of pride. Itâs a great feeling,â said Charles, who graduated from ßÙßÇÂț» in 2012 with a degree in cellular and molecular biology.
Vaccine development wasnât initially on Charlesâ career radar. She grew up and still lives in Rockland County, which is a melting pot of immigrants from all over the world, including a sizable Haitian community of which she is part.
âGrowing up, it was always the typical, âSo youâre going to become a doctor or a nurse or a lawyer.â I had no idea that being a scientist was something that I could do,â she said.
Her ßÙßÇÂț» experience
Charles initially opted for ßÙßÇÂț» for practical reasons: its reputation as a SUNY school and its pre-med track, which suited her high school dream of becoming a doctor. It was also an ideal distance from home: far enough away for the full college experience, but close enough to visit her family.
As the science of life, biology is a broad field. While Charlesâ studies largely focused on the cellular and molecular level, she had the opportunity to explore other aspects of the biological sciences in a wetlands ecology course, which involved trekking through the wetlands in the Universityâs Nature Preserve.
She first became involved in research under Associate Professor Claudia N.H. Marques, joining her lab as a student. Undergraduate research, of course, differs significantly from the pharmaceutical world: projects are smaller, and students typically donât have access to the same type of equipment or physical resources. But the scientific principles remain the same, and so, too, does the spirit of inquiry.
âI definitely think that set up my love for working on a lab bench,â Charles said of her undergraduate years. âThe little experiences definitely did help in migrating me toward this field.â
In addition to Marques, other ßÙßÇÂț» faculty and staff made a major impact on Charles. They include academic counselor Joanna Cardona-Lozada at the Educational Opportunity Program, then the coordinator of the ßÙßÇÂț» Success Program at the Louis Stokes Alliance for Minority Participation (LSAMP). Cardona-Lozada proved a ready font of advice from study tips to engaging with professors, giving Charles the opportunity to grow as an individual.
âThere was never a doubt that Melissa Charles was going to make a great impact on the world,â said Cardona-Lozada, noting that Charles would frequently stay after class to ask about research opportunities, internships and other ßÙßÇÂț» resources. âShe was a mover and a shaker seeking to empower herself with the necessary tools beginning with her freshman year, when I first met her.â
As a student, Charles was one of the founding members of Power United Ladies Striving to Elevate (PULSE).
âI ultimately ended up loving my experience there. I honestly say it to everyone: I had the best years of my life at ßÙßÇÂț», and I met a lot of the closest friends I have today when I was there,â Charles said.
Becoming a researcher
After graduating from ßÙßÇÂț», Charlesâ future plans shifted slightly to dentistry. She began both applying to dental schools and job-hunting after earning her masterâs in biomedical sciences at Rutgers University.
A recruiter reached out to her, and she landed a gig as a contract worker in Pfizerâs oncology division five years ago. After a year, she transitioned into a permanent position in vaccine research and has been there ever since.
âI loved it here so much, I ended up just staying,â she said. âEverything happens for a reason.â
Enter the ultimate unexpected turn: a global pandemic. When New Yorkâs lockdown began, Charles drove through eerily empty streets on the way to work. It reminded her of scenes from the apocalyptic film I am Legend. But once through the doors, the laboratory was âbusiness as usual, with an asterisk,â she said.
As always, deadlines had to be met and the science had to be sound. Any resource they might need was put at their disposal, even if it had to be trucked in from another part of the country.
As scientists, their own resources were also poured into the vaccine effort: six- to seven-day work weeks, coming in early and staying late. The experience deepened Charlesâ relationships with her colleagues, who needed to rely on and trust each other to complete an urgent task: the development of a viable vaccine.
âIt really puts everything that youâve already learned to the test,â she said. âEvery virus is different. Every protein and every polysaccharide has its own trials and tribulations, but you develop a broad knowledge base and youâre able to apply what youâve learned in order to get through things.â
Learning that she played a part in the development of the vaccine, her friends and family responded with both pride and curiosity. Charles takes her role as an educator seriously, pointing people to articles and studies that can answer their questions about the vaccine.
âLooking back, Iâm still amazed at the pace that we were able to work and maintain scientific integrity. It gives you just that much more of an appreciation for science,â she said.
She is an educator in other ways, too. Sometimes people are surprised to learn that she is a scientist. They often have an image of what a scientist looks like in their minds â someone like Albert Einstein, perhaps, Charles reflected.
But scientists can and do come from a wide range of backgrounds, including Rockland County. She had the opportunity to share that message with fourth-graders at her old school, talking to them about careers in science.
âTheyâre like, âWhat you did is so cool. I canât wait to be a scientist!â It warms my heart because thereâs that whole feeling of, âWow, now being a scientist is cool,ââ she said. âIt opens up the door for these kids who didnât know that this was a possible career route, something that they could eventually see themselves doing. And itâs important to have that diversity in every field.â
