What is the difference between antibodies and the vaccine in the context of COVID-19?
While antibodies and vaccines are both viable options to counteract the virus that causes COVID-19, there are major differences. While an antibody may immediately help treat an existing infection, a vaccine will train the immune system to protect against future infections.
