The CDC guidance says waiting three months after infection to get another Covid shot can result in a stronger immune response.
People who received three shots with the original vaccines and then caught Covid had more than 70% protection against infection from the omicron BA.1 and BA.2 variants, according to a study published inby Weill Cornell Medicine in Qatar. People who received two doses and caught Covid had more than 50% protection against infection.
But the study might not translate well to the U.S. because Qatar's population is much younger with only 9% of its residents age 50 or older, compared with more than a third of all Americans. Omicron BA.1 and BA.2 also are no longer circulating in the U.S. However, the now-dominant BA.5 variant is very similar to those earlier ones.
HHS Secretary Xavier Becerra said on Tuesday that public health officials are particularly focused on making sure people ages 50 and older get boosted this month. The CDC cleared a fourth dose of the old vaccines in March for this age group. A fourth dose was about 56% effective at preventing hospitalization from omicron BA.5 four months after receiving the shot,U.S. health officials believe the new boosters will provide stronger and more durable protection against Covid because the shots target the omicron BA.5 variant, whereas the old vaccines were developed against the original strain of the virus that emerged in Wuhan, China, in 2019.
