People who have been in close contact with someone who has COVID-19 are not required to quarantine if they have been fully vaccinated against the disease and show no symptoms (starting from two weeks after the final dose).
In general, quarantine means you should stay away from others and watch for signs and symptoms of COVID-19 if you are a close contact of someone with COVID-19. People who are confirmed to be ill with COVID-19 should isolate themselves.
If you develop severe symptoms of COVID-19, get medical care.
