However, he noted that the results of the study, which examined blood samples from 1,422 health workers in Hong Kong, are in line with the claims of vaccine manufacturers about their effectiveness: for BioNTech, this figure is 95%, and Sinovac — 50.
Pfizer Doses. Two doses are needed, 21 days apart (or up to six weeks apart, if needed) in the U.S. Some protection provided after the first dose. The CDC recommends an additional primary shot of an mRNA COVID-19 vaccine (at least 28 days after the second dose) for some people with weakened immune systems, such as those who have had an organ transplant.
Who can get the booster: Anyone who was inoculated with Pfizer-BioNTech for their (two-shot) primary vaccine series, and who is age 12 to 17 should get a Pfizer-BioNTech booster shot five months later, according to the CDC’s recommendations. If you are 18 or older, a Pfizer-BioNTech or Moderna mRNA booster is preferred in most situations.
