In the case of the SARS-CoV-2 vaccines, it takes approximately two weeks to develop the adaptive response that brings long-lasting protection against the virus. When you get the vaccine shot, what you’re noticing in the first day or two is part of the innate i...
Another reason that vaccines can be tricky to produce is that some viruses mutate so quickly that traditional vaccines are ineffective. A prime example is HIV (human immunodeficiency virus). Despite these hurdles, there is currently a tremendous movement to develop a vaccine to fight HIV and AIDS...
We've also seen some people raise concerns online about mRNA vaccines, such as the Pfizer-BioNTech vaccine, being a"new" technology. mRNA (or "messenger" RNA) is found in all living cells.mRNA is a messagethat tells cells how to make proteins that trigger the immune response inside the b...

How did we develop vaccines so quickly? These vaccines were able to be developed so quickly because the U.S. Congress directed nearly$10 billion to Operation Warp Speed, which was the project with the goal of producing and delivering 300 million safe and effective doses of vaccine by January...
Before they promoted bunk information on HIV and AIDS, Rogan, Kennedy, and Rodgers were spreading fringe theories about the coronavirus’s origins, as well as loudly questioning basic public health measures like vaccines, social distancing, and masks. All three men have also boosted the false ...
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
Robert Finbergis a physician who specializes in infectious diseases and immunology at the Medical School at the University of Massachusetts. He explains how this perception doesn't match the reality of how vaccines work. What does your body do when you get a vaccine?
mistakes creep into their genetic instructions. These changes might alter the protein coat slightly, so one year's batch of vaccine might not be as effective against the same type of virus next year. This is why new vaccines must be produced constantly to fight viral infections and prevent out...
