What Are FLiRT Covid Variants, Are They Extra Harmful?

Present vaccines ought to nonetheless have some profit in opposition to new variants: Dr Aaron Glatt (Representational)

New York:

The so-called FLiRT variants of SARS-CoV-2 coronavirus that trigger COVID-19 have been the dominant types of the virus circulating this 12 months globally, in response to the World Well being Group

The moniker FLiRT is an acronym for the places of the mutations the variants share on the virus’ spike protein. One in every of them, known as KP.2, has grow to be essentially the most generally circulating variant in america over the previous month, in response to the U.S. Facilities for Illness Management and Prevention.

Here’s what that you must find out about FLiRT.

HOW ARE THE FLIRT VARIANTS DIFFERENT FROM PREVIOUS VARIANTS?

The FLiRT variants, which additionally embody KP.2’s “parental” lineage JN.1, have three key mutations on their spike protein that might assist them evade antibodies, in response to Johns Hopkins College.

ARE THE FLIRT VARIANTS MORE CONTAGIOUS OR LIKELY TO CAUSE MORE SEVERE ILLNESS?

Dr. Aaron Glatt, chief of infectious illnesses at Mount Sinai South Nassau Hospital in Oceanside, New York, and a spokesperson for the Infectious Ailments Society of America mentioned he has not seen proof of an uptick in illness or hospitalizations, based mostly on the info he tracks and expertise together with his personal sufferers.

“There have been some important modifications within the variants, however I believe in latest instances it isn’t been as vital, most likely due to the immunity many, many individuals have already got” from prior sickness and vaccination.

CDC knowledge means that COVID-related hospitalizations have trended downwards in latest weeks and the variety of sufferers in emergency departments who’ve examined constructive for COVID has been about flat for the previous month.

Knowledge means that COVID charges are additionally down year-over-year. The speed of COVID hospitalizations is lower than half than a 12 months earlier, and the quantity of the antiviral Paxlovid presently being prescribed for COVID-19 is down round 60% from final 12 months, in response to analyst notes.

DO CURRENT VACCINES WORK AGAINST THE FLIRT VARIANTS?

The present vaccines ought to nonetheless have some profit in opposition to the brand new variants, Glatt mentioned.

Since 2022, well being regulators have requested vaccine makers to design new variations of the COVID-19 vaccines to higher goal circulating variants. Final month, Europe’s regulator mentioned vaccine makers ought to goal the JN.1 variant. U.S. consultants and regulators will meet to debate vaccine design on June 5 after having postponed the assembly from Might 16 in an effort to have extra time to “receive surveillance knowledge and different data.”

Makers of vaccines based mostly on messenger RNA (mRNA) know-how – Pfizer with associate BioNTech, and Moderna – say they’re ready for the June 5 assembly earlier than deciding on the design of their subsequent vaccines.

Novavax, which makes a extra conventional protein-based vaccine that takes longer to fabricate, has begun producing a shot focusing on JN.1 in line with suggestions from European regulators.
