Vaccination is the best protection against the COVID-19 virus. We are still learning about the length of time both natural immunity (immunity the body develops after an illness) and vaccine-induced immunity for COVID-19 will last.
There are booster recommendations for all three available COVID-19 vaccines in the United States. Millions of people are eligible to receive a booster shot and will benefit from additional protection. People who stay up to date with COVID-19 vaccinations do not have to quarantine after exposure to a person with COVID-19 as long as they remain symptom free. Check the CDC’s latest quarantine and isolation guidelines for specific details.
