FLiRT refers to a series of mutations, being more transmissible but with similar symptoms as previous strains, prompting a call for updated COVID shots from experts like Dr. Robert Murphy.
Multiple FLiRT variants like KP.2 and JN.1 account for a significant portion of recent COVID cases, emphasizing the importance of vaccination due to waning immunity over time.
Low vaccination rates across the US, with only about 23% of adults and 14% of children up to date on vaccines, raise concerns about the potential impact of FLiRT variants.
Although FLiRT variants have surfaced in Los Angeles County, their impact is not prominent yet, indicating a need for vigilance and proactive measures to prevent further spread.
