Booster shot
Booster shot refers to an additional dose of a vaccine that is given to an individual after the completion of the primary series of immunization. Booster shots are used to 'boost' the immune response, to ensure continued immunity against a disease because immunity can decrease over time.
Purpose of Booster Shots[edit | edit source]
The primary purpose of a booster shot is to re-expose the immune system to the immunizing antigen. This is done to stimulate the immune system and increase the body's ability to fight off infection. Booster shots are particularly important for diseases that the body does not naturally develop long-lasting immunity to.
Types of Vaccines Requiring Booster Shots[edit | edit source]
Several vaccines require booster shots for continued protection against diseases. These include vaccines for diseases such as tetanus, diphtheria, and pertussis (Tdap), measles, mumps, and rubella (MMR), and polio (IPV).
Booster Shots and COVID-19[edit | edit source]
In the context of the COVID-19 pandemic, booster shots have been discussed and implemented in several countries. The COVID-19 vaccine booster shot is given to people who have already received the primary series of the COVID-19 vaccine. The booster shot aims to enhance the immune response against the SARS-CoV-2 virus, particularly in the face of new variants of the virus.
