The results provide hope that people receiving SARS-CoV-2 vaccines will develop similar lasting immune memories after vaccination. The scientific studies suggest that taking two doses of the vaccines is significant for achieving the antibody response that provides overall protection and creates lasting immunity. Remarkably the current COVID-19 mRNA vaccines were 95 effective at preventing COVID-19 in clinical trials two weeks after the second dose.
