As the world continues to grapple with the Covid-19 pandemic, new variants of the virus continue to emerge. One such group of variants, collectively known as FLIRT, has been making headlines recently. Here’s what you need to know about these new strains and how they could impact the ongoing fight against the pandemic.
What are FLIRT Covid Variants?
FLIRT is an acronym that stands for four specific mutations found in the SARS-CoV-2 virus. These mutations include F486, L452, R346, and T478. The FLIRT variants are part of the Omicron family and have emerged from a lineage known as JN.1, which was responsible for a surge in Covid-19 cases during the previous winter season.
Among the FLIRT variants, KP.2 has become particularly prominent. By the end of April, it accounted for about 25% of new sequenced cases in the United States, as reported by the US Centers for Disease Control and Prevention (CDC). Other variants within the FLIRT family, such as KP.1.1, have not yet spread as extensively.
Should We Be Worried About FLIRT Covid Variants?
The concern with the FLIRT variants lies in their potential to spread quickly, possibly causing diseases that could be more severe than previous strains or could partially evade the protection provided by existing vaccines. Two preliminary studies have highlighted concerns regarding the ability of the FLIRT variants to bypass the immune defense provided by vaccines.
A study from Japan indicated that the KP.2 variant might be less infectious than its predecessor, JN.1, but could still pose challenges due to its ability to partially evade vaccine-induced immunity. Another study from researchers in China suggested similar findings, emphasizing the need for ongoing vaccine adjustments to keep pace with the evolving virus.
However, it’s too early to predict whether the FLIRT variants will lead to a significant new wave of infections. Current indicators, such as minimal virus levels in US wastewater and declining hospitalizations and deaths since January, suggest a major surge might not be imminent.
WHO Recommendations
In response to these developments, the World Health Organization (WHO) has recommended that future Covid-19 vaccine formulations should be based on the JN.1 lineage, from which the FLIRT variants have evolved. This recommendation aims to ensure that the vaccines remain effective as the virus continues to mutate.
Conclusion
Despite the challenges posed by new variants, the fundamental public health advice remains consistent: it is crucial to stay up-to-date with Covid-19 vaccinations. The regular updating of vaccines, akin to the annual updates for flu shots, may become necessary to maintain high levels of protection against emerging variants.
As we continue to navigate the pandemic, it’s essential to stay informed about new developments and follow public health guidelines to protect ourselves and our communities. By staying vigilant and taking necessary precautions, we can help slow the spread of the virus and keep ourselves and our loved ones safe.
