【COVID Vaccination study
】CU Medicine performed a comprehensive study with a large sample size to compare the vaccine efficacies of 24 combinations of COVID-19 vaccine regimens comprising seven types of vaccines worldwide. Results showed a three-dose mRNA regimen significantly decreases the risk of immunocompromised and elderly patients developing asymptomatic or symptomatic COVID-19 infections and most importantly, a third dose of the vaccine is required to protect against Omicron infection.
