The Food and Drug Administration on Monday approved updated COVID vaccines from Pfizer and Moderna that focus on the brand new subvariants of coronavirus, including XBB.1.5, as cases and hospitalizations surge within the U.S.

“The updated mRNA vaccines are each approved for people 12 years of age and older and are authorized under emergency use for people 6 months through 11 years of age,” the FDA said in a news release.

Everyone aged five and older can get the updated booster shot regardless of their vaccination status, the FDA said. Those that are vaccinated should wait at the least two months after their last COVID-19 shot.

The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will release the clinical recommendations regarding the usage of the vaccines after a gathering Tuesday. After the CDC approval, the shots will probably be available for public use through pharmacies, health clinics and other distribution centers by the top of the week.

The updated Novavax vaccine that uses protein-based technology, unlike the mRNA technology utilized in Pfizer and Moderna, remains to be under FDA review.

Health authorities hope the updated vaccines will provide higher protection against serious consequences of COVID-19, including hospitalization and death.

“Vaccination stays critical to public health and continued protection against serious consequences of COVID-19, including hospitalization and death,” Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said in the discharge. “The general public might be assured that these updated vaccines have met the agency’s rigorous scientific standards for safety, effectiveness, and manufacturing quality. We very much encourage those that are eligible to contemplate getting vaccinated.”

The FDA asked the drugmakers to update their vaccines to focus on XBB.1.5 in June when it was a dominant variant. In response to a CDC report from the primary week of September, XBB.1.5 accounts for under about 3% of latest COVID-19 cases. Nevertheless, other subvariants in circulation, including EG.5, which accounts for 21.5 % of latest cases, and FL.1.5.1, which accounts for about 14.15 % of latest cases, are all a part of the XBB subvariant family and the now approved boosters work against them.

The most recent omicron subvariant, BA.2.86, also generally known as “Pirola,” initially raised concerns resulting from its significant variety of mutations. Nevertheless, laboratory tests showed it will not be as proof against immunity as originally feared. Each Moderna and Pfizer announced last week that their boosters can trigger strong antibody response against the variant.
