Why Vaccines Matter

Vaccines are one of the most effective tools in public health. They work by training the immune system to recognize and fight specific pathogens without causing the disease itself. Widespread vaccination has eradicated smallpox, nearly eliminated polio, and dramatically reduced the incidence of measles, diphtheria, and many other diseases.

Catch-up schedules

If you or your child missed a vaccine, it is rarely too late to catch up. The CDC provides detailed catch-up schedules for children, adolescents, and adults. Your healthcare provider can review vaccination records and create a personalized plan to get back on track.

Herd immunity

When a high percentage of a community is vaccinated, it provides indirect protection to those who cannot be vaccinated (such as newborns or immunocompromised individuals). This concept, known as herd immunity, is critical for controlling outbreaks of contagious diseases.

Frequently Asked Questions

Are vaccines safe?+
Yes. Vaccines undergo rigorous testing through clinical trials before approval and are continuously monitored for safety. Side effects are generally mild (soreness at the injection site, low-grade fever) and resolve within a few days. The benefits of vaccination far outweigh the risks.
What if I missed a dose?+
Most vaccines have catch-up schedules. You usually do not need to restart a series if you missed a dose — just pick up where you left off. Your doctor or pharmacist can review your vaccination history and recommend the right plan.
Do adults need vaccines?+
Yes. Adults need vaccines too. Annual flu shots, Td/Tdap boosters every 10 years, COVID-19 vaccines, and age-specific vaccines like Shingrix (50+) and pneumococcal (65+) are recommended. Some adults may also need catch-up doses for childhood vaccines they missed.
Where can I get vaccinated?+
Vaccines are available at your doctor’s office, pharmacies, community health centers, local health departments, and many workplaces or schools. Check with your insurance for coverage details.
