FAQ: Your Questions about Immunization Answered

What is immunization?

Immunization is the process of making a person resistant to an infectious disease, typically by vaccination. Vaccines stimulate the body’s immune system to produce antibodies that protect against the disease.

How do vaccines work?

Vaccines contain weakened or inactive forms of a disease-causing organism (virus or bacteria) or parts of the organism. When a person is vaccinated, their immune system recognizes the foreign substance and produces antibodies to fight it. If the person is later exposed to the actual disease, their immune system will be able to quickly recognize and fight it off.

Are vaccines safe?

Vaccines are rigorously tested and monitored to ensure their safety. Serious side effects from vaccines are rare. The benefits of vaccination far outweigh the risks.

Why is it critically important to get vaccinated?

Vaccination protects individuals from serious and potentially life-threatening diseases. it also helps to protect the community by preventing the spread of infectious diseases. When a large percentage of the population is vaccinated, it creates herd immunity, which protects those who cannot be vaccinated, such as infants and people with certain medical conditions.

What vaccines do I need?

The vaccines you need depend on your age, health status, lifestyle, and travel plans. Talk to your doctor or other healthcare provider to determine which vaccines are right for you.
