What Are Boosters?

A booster shot is an additional dose of a vaccine given after the initial vaccination. Booster shots are used to provide additional protection against a disease, especially when the immunity from the initial vaccination is waning. They can also be used to provide protection against new strains of a virus or bacteria.

Booster shots are commonly recommended for diseases such as tetanus, diphtheria, and pertussis (whooping cough), as well as measles, mumps, and rubella (MMR). They are also recommended for certain populations, such as the elderly or immunocompromised, for diseases such as influenza and pneumonia.

Booster shots are important for maintaining immunity to diseases and preventing outbreaks. They can help to reduce the severity of a disease if you do become infected, and they can also help to protect others who are not vaccinated.

If you are due for a booster shot, it is important to get it as soon as possible to ensure the best protection against disease.
