Why vaccines after COVD-19 infections are effective

Caption

Top: A person is infected by the Alpha variant of SARS-CoV-2. Within a few weeks, antibodies are made that protect the person against the Alpha variant as well as Beta and Gamma variants which are very similar to the Alpha variant. Bottom: A person who (1) has recovered from COVID-19 and who (2) has received mRNA vaccine with components of the Alpha variant develops a strong immune response within a few weeks. The antibodies that are made in the body protect against the Alpha variant, the closely related Beta and Gamma variants as well as the more distantly related Delta and Omicron variants. People who have recovered from COVID-19 and then received the mRNA vaccine are also protected against new variants of SARS-CoV-2. Ill: Gerda Kaynova
