Vaccination is widely regarded as the most effective way to prevent yourself from suffering the most adverse effects of COVID-19. Please speak to your physician regarding any questions or concerns you may have about vaccination and also to learn where and how you may be able to get vaccinated.  People can also help protect themselves from respiratory illness with everyday preventive actions:
Avoid close contact with people who are sick.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.
