The spread of a new variant, NB.1.8.1, has raised concerns about the effectiveness of existing COVID-19 vaccines. However, according to the World Health Organization (WHO), currently approved vaccines are expected to remain effective against this variant.
The Centers for Disease Control and Prevention (CDC) recommends that everyone over 6 months old get vaccinated with the recommended vaccine. The FDA has also updated warning labels on mRNA COVID-19 vaccines to include warnings about a rare side effect of myocarditis, which affects 8 cases per 1 million people who receive the vaccine.
Despite these updates, some medical organizations have expressed concerns about the effectiveness of existing vaccines and are developing their own guidelines. The Advisory Committee on Immunization Practices (ACIP) has been criticized for its new members, including some with a history of anti-vaccine advocacy.
The American Academy of Pediatrics (AAP) and the AMA have reaffirmed their commitment to evidence-based immunizations, citing the importance of protecting public health. Meanwhile, the WHO continues to recommend that people who are at high risk, such as those over 65, pregnant, or immunocompromised, should receive the vaccine.
Ultimately, the best way to protect yourself from COVID-19 is to get vaccinated with a recommended vaccine. Consult with your healthcare provider for personalized guidance on COVID-19 prevention and vaccination recommendations in your area.
