How the Various COVID Vaccines Work

COVID vaccine hesitancy is on the rise, perhaps in the wake of pressure to speed approval beyond scientific reason. But I think some of the hesitancy might be due to confusion over how so many different vaccines can target the same pathogen – and why this is a good idea.

 

The ultimate voice of scientific reason, Anthony Fauci said in a media webinar:

 

"I'm cautiously optimistic that with the multiple candidates with different platforms that we're going to have a vaccine with a degree of efficacy that would make it deployable. The overwhelming majority of people make an immune response that clears the virus and recover. If the body can mount an immune response and clear the virus in natural infection, that's a pretty good proof-of-concept that you'll have an immune response against a vaccine."

 

Having choices would provide options for people not covered by some of the vaccines, like those over age 65 and people with certain medical conditions. "It's a misperception that vaccine development is a race to be a winner. I hope more than one is successful, with equitable distribution," Fauci said.

 

The vaccines work in what can seem to be mysterious ways, but all present a pathogen in some form, or its parts, to alert the immune system to mount a response. Understanding how it all happens isn't like learning "how the sausage gets made." Knowledge may quell fears.
