Natural Immunity Does Not Protect Against Omicron: Ministry of Health on Omicron

In the case of Omicron, it is not advisable to rely on natural immunity acquired from previous COVID-19 infections. If you have had COVID-19, it is still essential to get vaccinated.

Laboratory studies clearly show that recovery from a COVID-19 infection does not provide a level of protection that allows the immune system to prevent subsequent infections. Cases of reinfection are also possible; therefore, the best way to protect against infection and potential severe illness is through vaccination.
