We don’t yet know how long or how well a person remains immune to the virus after a natural infection, so people who have had COVID-19 infection should be offered COVID-19 vaccines (HSE Clinical Guidance).
The CDC also recommends that people be offered a vaccination regardless of whether they have had COVID-19, with or without symptoms. Information from clinical trials tells us that ‘currently authorized COVID-19 vaccines can be given safely to people with evidence of a prior SARS-CoV-2 infection’ (CDC, 2021).
A recent case report suggests that a person who has previously had COVID-19 could possibly be reinfected by the virus SARS-CoV-2, which causes COVID-19.
There is also a small possibility that a person may still get infected by the virus even if they have been vaccinated against COVID-19. However, the person will be protected from any possible serious illness that the virus can sometimes cause (HSE 2021).
So even though it is relatively rare to be re-infected, COVID-19 vaccination is advised for people who have had and recovered from COVID-19 (ECDC).To protect yourself and others from COVID-19, please continue to follow public health guidelines to maintain social distancing and wash your hands properly and often.
