While both protect from severe disease, inactivated
“Inactivated SARS-CoV-2 vaccines were used extensively in Asia, but are often considered inferior due to their induction of a lower antibody response compared to other types of vaccines,” said Dr. Anthony Tanoto Tan, senior co-author of the study. “This means that they might not have been as good at preventing infection, but several studies have shown that they are highly capable of thwarting the development of severe COVID-19.” Tan is a Senior Research Fellow with the Duke-NUS’ Emerging Infectious Diseases (EID) Program.
Four COVID-19 vaccines are approved or authorized in the United States by the FDA: Pfizer-BioNTech, Moderna, Novavax, and Johnson & Johnson’s Janssen (J&J/Janssen). Pfizer-BioNTech and Moderna are Messenger
However, unlike the mRNA vaccines, the inactivated virus vaccines did not appear to trigger cytotoxic CD8 T cells known for their ability to kill virus-infected…
