how vaccines work




terms to remember
Terms To Remember
  • Antibodies: Special body proteins that fight viruses and bacteria
  • Immunologic Memory: The body’s ability to respond to viruses or bacteria following immunization or infection; this ability often is retained for many years.
  • Community Immunity: The concept that immunizing all children who can be vaccinated protects those who have not been or cannot be vaccinated
even 2 500 years ago people knew immunity worked
Even 2,500 Years Ago, People Knew Immunity Worked.
  • The time: 500 B.C.
  • The place: Greece
  • The observation: Greek physicians noticed that people who survived smallpox never got the disease again.
  • The insight: Becoming infected by certain diseases gives immunity.
vaccines help your body prepare
Vaccines Help Your Body Prepare.
  • Vaccines contain weakened or killed versions of viruses or bacteria.
  • They prepare your body to fight off disease.
  • When a vaccine gets into your body, you make antibodies—special proteins that fight the intruders.
  • Remember…what’s in the vaccine is just strong enough to promote the body’s response to make antibodies, but much weaker than the viruses or bacteria in their natural, or “wild,” states.
  • If you haven’t been vaccinated, wild viruses or bacteria can overwhelm your system, causing serious illness or even death.
antibodies become part of the body s memory
Antibodies Become Part of the Body’s “Memory”.
  • Once antibodies are produced in response to a vaccine, they become a permanent part of the body’s immune system.
  • Then, if there is exposure to the natural or “wild” viruses or bacteria, the antibodies will fight off infections.
  • There’s a scientific name for this: “immunologic memory.” It means you’ll respond quickly to viral or bacterial invasion.
  • “Immunologic memory” lasts longer for some vaccines than for others. Sometimes re-vaccination is required to maintain protection.
some children are not immunized but they can be protected
Some Children Are Not Immunized,But They Can Be Protected.
  • Some parents choose not to have their children immunized for philosophical or religious reasons.
  • These unprotected children can be a source of infection to others who, for health reasons, can’t be immunized.
  • A vaccinated child can help prevent disease from spreading. This is why it’s so important for as many children as possible to stay fully vaccinated.
  • If too many people go unvaccinated, rare diseases may become common again.
community immunity



“Community Immunity”
  • Children who are immune are protected from disease. They can’t get the disease and they can’t give the disease.
  • If enough children are vaccinated against a disease then the disease cannot spread into their community. This is known as “Community Immunity”.
it s a small world and that s a big reason to get vaccinated
It’s a Small World, and That’s a Big Reason to Get Vaccinated.
  • Today, international travel takes millions of Americans to foreign countries every year—countries where vaccine-preventable diseases like polio or measles may be present.
  • Traveling to places like that can be deadly for children (and adults) unless they are immunized.
  • Some countries have serious infectious diseases that we don’t routinely vaccinate for in the U.S., although vaccines are available. Check with your doctor before traveling.
  • Phone the CDC’s Travelers’ Hotline toll-free at 1-877-FYI-TRIP (877-394-8747).
key facts
Key Facts
  • Vaccines give your body a “memory” of the disease—after you’re vaccinated, you’ll be ready to fight the disease if exposed.
  • Some children can’t be vaccinated for medical reasons, and others aren’t vaccinated for philosophical or religious reasons.
  • Vaccinating as many children as possible is the best way to protect everyone.
  • Whenever possible, vaccinate children before they travel to countries where childhood diseases persist. Diseases such as measles are still common in some countries.
