How long will immunity last if I get vaccinated?

Research is ongoing and data is not yet available on the duration of protection that the vaccines will provide, though Pfizer recently stated that it is likely people will need a 3rd booster dose at 12 months. COVID-19 variants will likely play a big role in determining the duration of protection and the need for another booster dose.
