“At this point the advice remains the same,” he said, referring to the vaccines which require two doses. “It’s going to be two vaccinations even if you have had COVID in the past. We just don’t know how strong and how long your immune response is from illness.”

Hnida did point to new research released in the past two weeks with a number of studies focused on the immune response to the vaccine in people who have already had COVID.
“It turns out, simply one single vaccine does wind up increasing the antibodies against COVID over a thousandfold. Not only is the antibody response large, it appears to generate a very strong and robust response in terms of being to able to fight off the things such as the mutated strains or variants.”
