💉 For the Vaccinated
Health experts emphasize the importance of staying up to date with COVID-19 vaccinations. While NB.1.8.1 may exhibit some immune evasion, existing vaccines are expected to continue providing protection against severe disease and hospitalization.

🤔 For the Unvaccinated or Vaccine-Hesitant
For individuals who are unvaccinated or hesitant about vaccination, it’s crucial to stay informed and practice preventive measures. Maintaining good hygiene, wearing masks in crowded spaces, and monitoring for symptoms like sore throat, fever, and fatigue can help reduce risk. As always, consulting with healthcare providers for personalized advice is recommended.
