Scientists have identified a new group of highly transmissible omicron subvariants in the U.S., named FLiRT, with one strain, KP.2, becoming the dominant strain as of May 11. These subvariants have mutations in their spike proteins, which allow the virus to enter cells and evade the immune system. Despite these differences, current vaccines are still expected to provide some level of immunity against these new strains. A new vaccine based on the FLiRT subvariants is expected to be available in September and may offer better protection.
The FLiRT subvariants, direct descendants of the previous JN.1 subvariant, are more infectious due to mutations in the spike protein. While the current vaccines are based on a different subvariant (XBB.1.5), they are likely to offer cross-immunity against FLiRT. Although the severity of the new subvariants is still being studied, it is expected that there will be an increase in COVID-19 cases, hospitalizations, and deaths due to increased transmission. Most infected adults experience the new variants as a flu-like illness, with the potential for long COVID in repeated infections.
Those who are more vulnerable, such as the elderly or people with underlying health issues, are at risk of severe illness from the new variants and should ensure they are up to date with their booster shots and wear N95/P2 masks in public places. It is also recommended to have a plan in place with healthcare providers for quick access to antivirals if needed. In the case of a respiratory infection, it is important to stay home to prevent spreading it to others.
While concerns about the new FLiRT subvariants exist, it is expected that the current vaccines will still provide some level of protection against these strains. As more research is conducted, a better understanding of the severity and implications of these variants will emerge. It is essential for vulnerable individuals to take precautions and stay informed about the evolving situation to protect themselves from serious illness. If experiencing health concerns, individuals are encouraged to reach out to experts for advice and support.
