Types of Vaccines

Infectious diseases can be prevented by using immunizations (also called vaccination) that induce either active or passive immunity. Active immunity is induced by vaccines prepared from pathogens or their products. Passive immunity is provided by the administration of preformed antibodies.

The term ‘vaccination’ is derived from ‘Vaccinia’, the first-ever vaccine (smallpox vaccine) which protects against smallpox. Vaccines can be categorized into six different types based on the process used to make them. These are;

  1. Live-attenuated vaccines
  2. Inactivated vaccines
  3. Subunit vaccines
  4. Toxoid vaccines
  5. Viral vector vaccines
  6. Messenger RNA (mRNA) vaccines
