Natural immunity is good. Getting vaccinated after being sick with COVID-19 is better.
Many people have caught COVID-19 over the past 20 months, despite their best efforts, or because they didn't take enough precautions against the coronavirus.
Data is just starting to emerge about how protected they may be against another infection.
As with most illnesses, contracting COVID-19 provides immune "memory" that helps protect against a future infection. But it's still unclear how sick a person has to get with COVID-19 to develop enough immune memory to be protective and for how long. That's why the Centers for Disease Control and Prevention recommends even people who have had COVID-19 get vaccinated against it.
A growing body of research suggests infection plus vaccination provides the strongest protection against a wide range of variants, possibly for a long time.

Pretty sure we had Covid before it was "officially" here...all the symptoms. Now fully vaccinated, we should be in good shape.
