The US Food and Drug Administration (FDA) yesterday issued new instructions to COVID vaccine manufacturers regarding the next round of updated COVID shots.

 

In a document posted on the FDA website, the agency said COVID-19 vaccines used in the United States starting in fall 2025 should be based on JN.1 lineage strains, preferably the LP.8.1 strain, which, according to the Centers for Disease Control and Prevention, currently accounts for 70% of US COVID cases.... The current US COVID vaccines use the KP.2 strain, which is within the JN.1 family of variants.

...

The VRBPAC recommendation is similar to the position of the World Health Organization's COVID-19 vaccine composition committee, which said on May 15 that JN.1 and KP.2 vaccines are still appropriate, but LP.8.1 is a suitable alternative.
