Understanding mRNA Covid-19 Vaccines
Messenger RNA vaccines, also called mRNA vaccines, are some of the first COVID-19 vaccines authorized for use in the United States. mRNA vaccines are a new type of vaccine to protect against infectious diseases. They teach the cells of our body to make a protein that triggers an immune response. This immune response leads to the production of antibodies which protects us from getting infected if the real virus enters our body.
We are sitting down with Dr. Drew Weissman, who with his former colleague Katalin Kariko, developed the mRNA technology enabling the creation of the Covid-19 mRNA vaccines, to learn more about the science behind mRNA, the technology and his journey.
Dr. Weissman is a professor of Infectious Diseases in Penn’s Perelman School of Medicine and has been working on using RNA in vaccines for more than 15 years.
