National Immunization Awareness Month

A vaccine is a medical invention that works with the body’s natural defenses to create protection against harmful germs. By introducing the immune system to a dead or weakened version of that germ, vaccines allow the immune system to identify the risk and produce antibodies to fight it in the future.

“Vaccines help us avoid the need for medications to treat an illness, and they also prevent us from spreading diseases to our friends, family members, and other loved ones,” said Richard Brooks, M.D., a Hospitalist at the Washington DC VA Medical Center.  

Vaccines are safe and effective and can protect those around you through herd immunity. Herd immunity is achieved when a certain percentage of a population is vaccinated against the same disease. This method protects those in the community, or “herd”, that cannot receive the vaccine for health reasons, by breaking the chain of transmission among the vaccinated and forcing the disease to die out of the community.

“Through herd immunity, we have completely wiped-out deadly diseases like smallpox and polio, on a global scale,” said Brooks. “We save lives when we come together and get vaccinated for those who can’t.”

Because the immune system is designed to remember, once exposed to the proper dosage of a vaccine, it will typically protect you against that germ or virus for years, decades or, in some cases, your lifetime. Recommended vaccines and immunizations depend on your age, health status, and family history. Brooks encourages everyone to talk to their primary care provider to find out what vaccinations they might need.

“If you have concerns about vaccines or are unsure which vaccines might be right for you, talk to your VA primary care provider,” said Brooks. “We want to listen to you and help you make the best choice for your health.”
