High Protection Against JN. 1 COVID-19 Variant Provided by Updated Vaccine

The JN.1 COVID-19 variant now makes up more than 93 percent of cases, according to latest tracking from the Centers for Disease Control and Prevention (CDC). That’s a major leap from two months ago when this highly mutated version of the virus accounted for just 1 in 5 infections.

Although evidence suggests that JN.1 is either highly transmissible or better at evading our immune systems, as of February 2, key indicators from the CDC are showing decreasing levels of COVID activity nationally, with hospitalizations and test positivity trending down in recent weeks.

A CDC study published at the beginning of this month suggests that the newest COVID-19 vaccine may be playing a role in keeping the JN.1 variant from having a more severe impact on public health.

Latest Shot Defends Against Both Severe and Mild Infection

Based on an analysis of more than 9,000 individuals who were tested for COVID-19 at participating CVS Pharmacy and Walgreen pharmacies between September 21, 2023, and January 14, 2024, researchers found that those who’d received the updated COVID-19 vaccine had about 54 percent increased protection against symptomatic JN.1 infection compared with those who hadn’t received the updated vaccine.
