At a glance

Mechanism of action

As a vaccine, it contains antigens (either live attenuated, inactivated, or recombinant) that train the immune system to recognize and respond to specific pathogens. The exact mechanism depends on the vaccine type and target pathogen, but generally involves activation of both humoral (antibody) and cellular (T-cell) immunity to confer protective immunity against infection.
