What it means
Vaccination refers specifically to the act of receiving a vaccine — a biological preparation that induces immunity to a particular infectious disease. Vaccines may be given as an injection, nasal spray, or oral dose. They contain weakened or inactivated pathogens, specific proteins, or mRNA instructions that teach the immune system to respond to a real infection. Routine vaccination in the US follows schedules set by the CDC for children and adults. Annual flu vaccination is widely recommended. Vaccines have largely eliminated or drastically reduced diseases like smallpox, polio, and measles. Most vaccines are covered under preventive care at no cost-sharing under the Affordable Care Act.
