Nearly half of Europeans died from the plague. Now a new study shows a protective gene mutation that survivors passed on to help with future outbreaks might cause other problems.
Some countries are moving ahead with plans to offer a fourth dose of COVID-19 vaccine. But studies are raising questions about the potential advantages of this extra booster.
The Centers for Disease Control and Prevention reports that both infection-induced and vaccine-induced immunity are durable for at least six months — but that vaccines are more consistent in their protection and offer a huge boost in antibodies for people previously infected.
That's how some scientists describe the findings of a series of studies looking at the antibodies created by individuals who were infected by the coronavirus and then had an mRNA vaccine.
New studies look at how the mRNA vaccines affect the cells in your body in the short run and the long run. The findings are a counterpoint to concerns about waning immunity.
Worries about waning immunity and talk of COVID booster shots has some Americans checking their antibody levels to see if they're protected. But scientists warn blood tests don't tell the full story.
Researchers found that a class of antibodies in a monkey's blood provides protection from COVID-19. If that hold true for humans, a blood test may predict whether a vaccine candidate is working.
