What happens if COVID-19 mutates?
Thanks to science fiction, the word “mutant” has become associated in popular culture with something that is abnormal and dangerous. Yet in reality, viruses like SARS-CoV-2, the virus that causes COVID-19, are mutating all the time and often this process does not have any impact on the risk the virus poses to humans.
Does the COVID-19 vaccine work on new mutations?

There is promising evidence to suggest that the current vaccines will protect you from most variants, or mutations, of COVID-19 that are currently spreading in the United States. It is possible that some variants might cause illness in some people after they are vaccinated. However, if a vaccine is found to be less effective, it could still offer some protection. Researchers are monitoring how the new COVID-19 variants may affect how vaccines will work in real-world scenarios.

How effective is J and J vaccine?
Clinical trials put the J&J vaccine’s efficacy at around 66% against the original coronavirus strain, while the two-shot Pfizer and Moderna vaccines were more than 90% effective. CDC Director Dr. Rochelle Walensky said Tuesday the Delta variant now makes up around 83% of all Covid cases in the United States.
Do I have to self isolate if fully vaccinated?
However, anyone who tests positive or develops symptoms will still need to self-isolate, regardless of their vaccination status.
