The Omicron variant has morphed into more than half a dozen different strainsthe latest of which include BQ.1.1 and XBB.1, and XBB.1.5. "I don't think it's a sustainable strategy to ask people to get boosters of the same vaccine every two months or three months. The CDC's move clears the final hurdle for eligible Americans to be able to get another round of the booster shots that were rolled out last year from Moderna and Pfizer-BioNTech, which had been . Compared to original and delta variants, the proportion of omicron-specific antibodies detected in participants blood dropped rapidly from 76% four weeks after the second shot to 53% at weeks eight to 10 and 19% at weeks 12 to 14, the researchers found. Perhaps, instead, the goal may need to shift from stopping infections to making sure everyone is protected against severe disease over the long-term. As SELF has reported, vaccines are the best way to prevent severe COVID outcomes like hospitalization and death.. Do Bivalent Boosters Protect Against XBB.1.5? It's a really good time to get yourself protected," Dr. Ashish Jha, the White House's Covid response coordinator, told the "In the Bubble with Andy Slavitt"podcastearlier this month. Based on the data from his study, which showed waning of protection after the.

In the fall of 2022, the Food and Drug Administration (FDA) authorizedand the Centers for Disease Control and Prevention (CDC) recommendedtwo updated boosters. A recent study found that the bivalent COVID-19 boosters produce neutralizing antibodies against Omicron subvariant XBB. In a study published in late January in The New England Journal of Medicine (NEJM), the bivalent vaccine was 58.7% effective against hospitalization compared to 25% for the original, monovalent vaccine. That said, even if most of those illnesses aren't severe enough to put people in the hospital, it doesn't mean we can stop worrying about COVID. The CDC signoff means shots could begin immediately. When the mRNA COVID-19 vaccines were first unveiled in December 2020, medical experts touted the benefits of this new technology, saying formulations could easily be tweaked someday to match a quickly changing virus. Protection against infection is likely short-term, lasting less than six months, but protection against severe disease appears more robust, researchers with the U.K. Health Security Agency reported Friday.

That could reflect the fact that people who have been infected tend to start out with a higher baseline of antibodies against SARS-CoV-2 than those who have never encountered any variant. The researchers had blood samples from the day the participants received their fourth dose, as well as samples taken one month later, so they could measure antibody levels against BQ.1.1 and XBB.1 in the same people. On the other hand, she says, protection against severe disease doesn't depend so heavily on antibodies. This press release features multimedia. Will You Need Another COVID Booster This Spring? COVID data tracker: Variant proportions. "The vaccine's efficacy against infection relies on our level of antibodies because they are really our first line of defense against SARS-CoV-2," says immunologist Jennifer Gommerman at the University of Toronto. Are Bivalent Boosters Better than Original Vaccines? Pfizer's COVID-19 booster appears to protect against the Omicron variant for at least four months, according to a new preprint study.
