In the real-world CDC data, researchers show that the bivalent booster is reducing COVID-19 among those who receive it, and that protection from disease against the newest variants is similar to that against the BA.5 variant. To find this, a team at Imperial College London created a new model that used limited information about the omicron variant, according to BBC News.

Once you're caught up on vaccines, Hafiz said that monitoring community rates and masking in crowded settings will help reduce the [infecton] risk" of COVID moving forward. Here's what experts want you to know about the new bivalent COVID boosters and XBB.1.5. A recent study found that the bivalent COVID-19 boosters produce neutralizing antibodies against Omicron subvariant XBB. This week, Indonesia started a program to give booster shots to the elderly and people at risk of severe disease. Researchers behind the NEJM paper analyzed data from vaccinated and boosted people enrolled in the trials for the original Pfizer-BioNTech vaccine, who received a fourth dose of the original vaccine, and another group that received three doses of the original vaccine and a fourth dose of the bivalent vaccine. It looks like XBB is more contagious than previous variants, but doesn't cause more severe diseaseat least when you look at the number of hospitalizations. We strive to set the standard for quality, safety and value in the discovery, development and manufacture of health care products, including innovative medicines and vaccines. Most people who are immunocompromised can get additional doses at least two months after their last doses, according to the agency. The FDA set the minimum wait time at two months. BA.4 and BA.5 Omicron subvariant lineages. Covid News: Pfizer says booster provides protection against omicron in Half of the vaccine targets the original strain, and the other half targets the BA.4 and BA.5 Omicron subvariant lineages, which are predicted to continue circulating this fall and winter. Equivalent studies on the omicron-specific boosters aren't published yet but some experts say you'll be fine either way. If you're with people who could become quite sick if you transmitted it to them, even if you had mild disease, that is something to consider., Lifestyle also plays a role, Dr. Murray adds. Pfizer's COVID-19 booster appears to protect against the Omicron variant for at least four months, according to a new preprint study. Pfizer and BioNTech Announce Omicron-Adapted COVID-19 Vaccine That's the same size as a single dose of Pfizer's monovalent vaccine, which has 30 micrograms targeting the original strain. "We know respiratory viruses circulate at much higher levels in the fall and winter. A resident receives a dose of the Pfizer COVID-19 vaccine at a health center in Jakarta, Indonesia, on Jan. 13. Specifically, the researchers found that right after the third shot of the Pfizer vaccine, protection against a symptomatic infection is pretty good. The bivalent was also 61.8% effective against infection versus 24.9% for the monovalent vaccine. How Effective the Original Vaccines Are Against Omicron | Time According to a small study published in The New England Journal of Medicine, the bivalent vaccines produced neutralizing antibodies against XBB. The study, which drew data from people 12 and over who were included in North Carolinas vaccine registry, was done during a time when Omicron BQ.1 and BQ.1.1 were circulating. So how well does it protect against the newer ones? Are COVID-19 Vaccine Boosters Necessary? : NPR ", "Keep in mind, too, that omicron is very different than the original version of SARS-CoV-2, which is what we've been immunized against," Gommerman adds. The people who got the bivalent boosters had better neutralizing activity than people who got either one or two monovalent boosters.
