Immunization Schedule by Age: What Parents Need to Know

Vaccines are powerful tools in protecting children from serious diseases like measles, polio, and whooping cough. At AFB Pediatrics in Pasadena, TX, Dr. Aldo Bejarano and his team help families follow the recommended schedule for routine immunizations. Understanding when these vaccines are given is key to keeping your child’s health on track and preventing the spread of illness.

Why Vaccines Matter

Vaccines teach the body's immune system to react and fight ugly bacteria or viruses. They protect the vaccinated child and create a "herd immunity" by keeping vulnerable individuals from getting an infection from some vaccines. Skipping or delaying vaccines increases the chances of preventable epidemics and high-level complications.

Key Vaccines by Age

Birth to 6 Months: To develop early immunity, infants receive several doses of vaccinations for hepatitis B, rotavirus, diphtheria, tetanus, pertussis (DTaP), Hib, pneumococcal disease, and polio between birth and 6 months of age.

6 to 18 Months: At this age, kids get extra doses of DTaP, Hib, polio, and pneumococcal vaccines. New vaccines introduced at this age are MMR (measles, mumps, rubella), varicella (chickenpox), and hepatitis A. Flu shots begin at 6 months every year.

4 to 6 Years: Kids get boosters for DTaP, polio, MMR, varicella, and the flu shot every year before school entry.

11 to 12 Years: As they age, preteens are recommended to receive Tdap (tetanus, diphtheria, pertussis), HPV (human papillomavirus), and meningococcal conjugate (MenACWY) vaccines. 

These are administered to prevent cancers, meningitis, and whooping cough.

16 to 18 Years: Teenagers above this age can receive the meningococcal B (MenB) vaccine, especially if they are at increased risk. The flu shot is still given annually at this stage.

Staying on Track

Well-child visits are the perfect time to ensure your child's immunizations are up to date. Your pediatrician can provide a personalized catch-up plan if any doses are missed. Keep a written or digital record of your child’s immunizations and bring it to each appointment.

The Bottom Line

Vaccines are one of the best ways to safeguard your child’s health. By staying informed and sticking to the recommended schedule, you’re taking an important step to prevent disease and promote lifelong wellness. If you have concerns or need to check your child’s vaccination status, don’t hesitate to contact your pediatrician.
