Many people have been affected by COVID-19 over the last 20 months, despite their best efforts, or because they didn’t take enough precautions against the coronavirus. Data on how well they are protected from another illness is just starting to emerge.
COVID-19 vaccination provides immunity “memory” that helps you avoid getting infected in the future. But it’s still unclear how sick a person has to be with COVID-19 for their immune memory to develop and what length of time it takes. That’s why, according to the Centers for Disease Control and Prevention, everyone who has had COVID should get vaccinated anyway.
