Vaccines are one of the best ways to protect kids from serious illnesses. Following a recommended schedule helps children stay healthy at every age. This 2026 guide shows when children should get each vaccine. It’s based on the CDC’s official schedule for children and teens.
Newborn to 6 Months
Babies’ immune systems are just starting to work. Vaccines in the first months protect them from diseases that can be very serious.
| Age | Vaccine | Prevents |
|---|---|---|
| Birth | HepB Dose 1 | Hepatitis B |
| 1–2 Months | HepB Dose 2 | Hepatitis B |
| 2 Months | DTaP Dose 1 Hib Dose 1 IPV Dose 1 PCV Dose 1 Rotavirus Dose 1 | Diphtheria, Tetanus, Pertussis, Hib, Polio, Pneumococcal, Rotavirus |
| 4 Months | DTaP Dose 2 Hib Dose 2 IPV Dose 2 PCV Dose 2 Rotavirus Dose 2 | Boosts early immunity |
| 6 Months | DTaP Dose 3 HepB Dose 3 IPV Dose 3 (for some brands) PCV Dose 3 Rotavirus Dose 3 (for some brands) Flu vaccine (first dose for 6+ months) | Complete early protection |
At this age, vaccines help babies stay safe from infections that can be serious, even life-threatening.
6 Months to 18 Months
Toddlers are moving around more and exploring the world. Vaccines at this stage protect against common illnesses.
| Age | Vaccine | Prevents |
|---|---|---|
| 6–12 Months | Annual Flu Vaccine | Seasonal flu |
| 12–15 Months | MMR Dose 1 Varicella Dose 1 PCV Booster Hib Booster | Measles, Mumps, Rubella, Chickenpox, Pneumococcal, Hib |
| 15–18 Months | DTaP Dose 4 | Pertussis, Diphtheria, Tetanus |
This is a key stage for building strong immunity before preschool or daycare.
18 Months to 6 Years
| Age | Vaccine | Prevents |
|---|---|---|
| 18–23 Months | Annual Flu Vaccine | Seasonal flu |
| 4–6 Years | DTaP Dose 5 IPV Dose 4 MMR Dose 2 Varicella Dose 2 | Boosts immunity, ready for school |
Completing vaccines before school helps protect your child and others in the classroom.
7 Years to 10 Years
At this age, most children just need the annual flu shot. Additional vaccines may be recommended if the child has special health needs or risks.
11 Years to 18 Years
Teen vaccines protect against illnesses that can affect adolescents and adults.
| Age | Vaccine | Prevents |
|---|---|---|
| 11–12 Years | Tdap Booster HPV 1st or 2nd Dose (depends on schedule) MenACWY Dose 1 | Tetanus, Diphtheria, Pertussis, HPV-related cancers, Meningococcal disease |
| 16 Years | MenACWY Booster MenB Series (optional, based on risk and doctor advice) | Meningococcal disease |
| Every Year | Flu Vaccine | Seasonal flu |
These vaccines help teens stay healthy at school, sports, and social events.
Why Following the Schedule Matters
- On-time protection: Vaccines work best when given at the right age.
- Community immunity: Protects not only your child but also friends and family.
- Catch-up is possible: Missed vaccines can be given later according to CDC guidelines.
- Special cases: Children with chronic illnesses or immune problems may need adjusted schedules.
Staying on schedule ensures your child gets full protection at every stage of growth.
