Vaccine FAQ

Vaccinations help protect your child from serious diseases by teaching their immune system to recognize and fight specific bacteria or viruses. Most vaccines are given as injections.

Vaccines protect against serious illnesses such as measles, mumps, rubella, influenza, polio, tetanus, whooping cough, chickenpox, rotavirus, and hepatitis A and B, among others. While vaccines don’t prevent minor illnesses like colds, they are vital for shielding your child from life-threatening diseases.

Yes, vaccines are rigorously tested for safety before being approved and are continuously monitored. Most side effects, like mild soreness or a low-grade fever, are temporary and manageable. Serious reactions are extremely rare, and the benefits far outweigh the risks. If you have concerns, your child’s healthcare provider can address them.

Your healthcare provider will provide a schedule and reminders for your child’s vaccines. Typically, the first vaccine (hepatitis B) is given shortly after birth, with multiple visits needed before age two to complete the recommended doses.

Yes. Mild illnesses, low-grade fevers, or antibiotics generally do not prevent your baby from receiving vaccines. If you’re unsure, consult your child’s healthcare provider.

If you miss a dose, your child doesn’t need to start over. The provider will resume the schedule from where it left off.

Ask your healthcare provider for a vaccination record card and bring it to every appointment. This record will ensure your child’s immunizations are up to date.

No. It’s never too late to begin or catch up on vaccinations. Talk to your provider about starting or completing your child’s immunization schedule.

Vaccines are often free or low-cost for families in need. Contact the CDC-INFO Hotline at (800) 232-4636 or your local health department for resources.

Yes. While some diseases are rare in the U.S., they remain common in other countries and can be brought here through travel. Vaccinating your child helps prevent outbreaks and protects them from serious harm.

No. While breastfeeding offers temporary protection against minor illnesses, it does not shield against vaccine-preventable diseases. Vaccines provide targeted, long-term immunity.

The risks of natural infection are far greater than any risk from vaccination. Diseases like measles or chickenpox can lead to severe complications, including paralysis, deafness, or even death. Vaccination is a safer, more effective way to build immunity.
