New COVID vaccine effective against dominant variant


News Team

A recent study has found that the updated COVID vaccines provide strong protection against symptomatic infection with both the XBB.1.5 and JN.1 omicron variants. Experts recommend getting vaccinated as soon as possible.

The new government research shows that updated vaccines cut the chances of getting a symptomatic infection in half. Study author Ruth Link-Gelles, director of the COVID and RSV vaccine effectiveness program at the US Centers for Disease Control and Prevention (CDC), stated that the vaccines are providing the protection that was expected. The vaccines work just as well against JN.1, the variant that has been fueling the majority of COVID infections in the United States since late December.

The CDC analyzed trends among more than 9,000 adults who received COVID tests at Walgreens and CVS pharmacies between mid-September and mid-January. The study found that the vaccines provide protection for JN.1, which is the most common variant today.

The latest COVID vaccines have only been available since September, so this analysis could only track effectiveness for about four months after vaccination. The protection of the latest vaccine is expected to wane over time.

Wastewater data suggests the virus continues to circulate at high levels and is still causing many COVID hospitalizations and deaths each week. Only about 22 percent of adults and 11 percent of children have received the latest COVID vaccine, according to CDC estimates.

The CDC recommends getting a COVID vaccine as soon as possible, as the extra protection is going to be a big help. For more information on COVID, visit the US Centers for Disease Control and Prevention (CDC).
