Lasting immunity found after recovery from COVID-19

According to this article on the NIH website if you've already had Covid-19 chances are that you don't need to get the vaccine at all. Even six to eight months after recovering from the virus patients still mostly had immunity, though it was slightly declining at that stage.

The researchers found durable immune responses in the majority of people studied. Antibodies against the spike protein of SARS-CoV-2, which the virus uses to get inside cells, were found in 98% of participants one month after symptom onset. As seen in previous studies, the number of antibodies ranged widely between individuals. But, promisingly, their levels remained fairly stable over time, declining only modestly at 6 to 8 months after infection.
