New BQ.1.1 Covid variant rising quickly n the US makes vaccines FOUR TIMES weaker, study suggests

• Researchers found that the budding BQ.1.1 strain can evade the bivalent booster
• The bivalent shot was tailored specifically for the Omicron variant
• BQ.1.1 now makes up a third of Covid cases in the US, the most prevalent strain

A rising Covid subvariant soon to become dominant across the US makes the updated bivalent vaccines significantly weaker, according to a study.

The BQ.1.1 strain - a descendent of BA.5 and the original Omicron variant - already makes up a third of cases nationwide and is out-competing all other versions of the virus, suggesting it has an evolutionary edge.

Researchers from the University of Texas tested the new strain against Pfizer and Moderna's new bivalent shots - designed to target the original Omicron - to see if the new variant spreads so quickly because it can duck vaccines.

They did so by taking blood of Americans given those vaccines and exposing them to the virus in a lab. 

Results showed the number of antibodies - immune proteins that help fight viruses - produced in response to BQ.1.1 were four times lower than those that prevented the BA.5 strain.
