There has been some very good news this week about the prospects of returning back to normal from the COVID pandemic earlier than thought. The first ray of sunshine is that herd immunity may be just weeks away in the United States.
This morning comes news that one of the reasons we are speeding toward herd immunity is that the various COVID vaccines are providing enough protection with just one dose.
Covid-19 survivors who have gotten a first dose of Covid-19 vaccine are generating immune responses that might render a second shot unnecessary, potentially freeing up limited vaccine supply for more people, several new research papers suggest.
The research, while preliminary, found that the previously infected people generated protection against the disease quickly and at dramatically higher levels after a first shot of the current two-shot regimens when compared with people who were vaccinated but hadn’t been sick.
“Everyone should get vaccinated. Not everybody needs two shots,” said Viviana Simon, a professor of microbiology at New York’s Icahn School of Medicine at Mount Sinai and an author on one study. “As long as we can’t deliver as much vaccine to everybody who wants it, I think it’s an important consideration.”
This is important news which, if it holds up under more study and scrutiny, would help offset the bumpy vaccination rollouts many countries seem to have faced over the last few weeks.
Giving just one dose means health officials could redeploy excess doses to more people and speed the reach of vaccinations, which vaccine experts and health authorities say is crucial as new forms of the virus increase transmission. Limited initial supply has contributed to the bumpy rollout of the vaccine and forced governments to favor high-risk individuals ahead of others.
