COVID-19 survivors who have received one shot of either COVID-19 vaccines might have enough of an immune response to not need a second shot, The Wall Street Journal reports.

  • Several new research papers suggested that “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,” The Wall Street Journal reports.

Viviana Simon, a professor of microbiology at New York’s Icahn School of Medicine at Mount Sinai and an author on one study on the issue, told The Wall Street Journal that this should be considered during the early phase of vaccine rollout.

  • “Everyone should get vaccinated. Not everybody needs two shots,” Simon told The Wall Street Journal. “As long as we can’t deliver as much vaccine to everybody who wants it, I think it’s an important consideration.”

Similarly, Florian Krammer, a virologist at the Icahn School of Medicine at Mount Sinai, told The New York Times that only one shot would spare some people from getting side effects from the second shot.

  • “I think one vaccination should be sufficient,” Krammer told The New York Times. “This would also spare individuals from unnecessary pain when getting the second dose and it would free up additional vaccine doses.”

However ...

Per The Wall Street Journal (via Fox Business), giving COVID-19 survivors one shot would actually cost additional money since testing would be need to be done to determine who has COVID-19 antibodies and who has enough to avoid two shots.
