A vast array of childhood infections can be prevented by starting immunization early and sticking closely to the vaccination schedule laid out by the below childhood vaccination checklist created by Carrington.edu. This carefully researched schedule removes all doubt from the equation and ensures that children remain up to date with immunization. Some parents remain suspicious, however, as they don’t understand why the schedule is designed the way it is.

The Importance of Early Vaccinations

Many parents express doubts about the early age at which children are vaccinated. While exposing newborns and infants to the causative agent of an infectious disease (or its byproducts/substitutes) may seem alarming, extensive research indicates that this approach is most effective. Children are most vulnerable to the diseases for which they are vaccinated when they are under the age of two, and yet, this is exactly when vaccinations have the biggest impact on their immune systems.

Why So Many Doses?

Vaccinations begin early, but regular doses continue through the first several years of childhood, with periodic updates and the addition of a few new vaccinations later on. According to the American Academy of Pediatrics, many vaccines will not work as well as intended unless children receive three or four doses. These doses need to be spread out a certain amount to work best. Cleveland Clinic has recommended these vaccines for school-going children, which can protect children from 16 potentially harmful diseases.

Age Name of Vaccine Protects against
At Birth Hepatitis B (HepB) 1 st dose Protects against the hepatitis B virus , which can cause lifelong infection, cirrhosis of the liver, liver cancer, liver failure, and death

2-9 years Influenza (IIV; LAIV) annual vaccination (IIV only) 1 or 2 doses
4-6 years Diphtheria, Tetanus, and Acellular Pertussis (DTap:<7 yrs) 5 th dose
Inactivated poliovirus (IPV<18 yrs) 4 th dose
Measles, Mumps, Rubella (MMR) 2 nd dose
Varicella (VAR) 2 nd dose
10-18 years Influenza (IIV; LAIV) annual vaccination (IIV only) 1 or 2 doses
11-12 years Meningococcal 1 st dose Helps protect against meningitis, which can cause fever, headache, stiff neck, nausea, vomiting, and confusion
Tetanus, Diphtheria, and Acellular Pertussis (TDap:>7 yrs)
Human papillomavirus 3-dose series Protects against cancer caused by HPV infections
16 years Meningococcal-booster dose

Although the recommended vaccine schedule is appropriate for most children, there are occasional exceptions. For example, experts at the Mayo Clinic do not recommend that children with HIV use the typical schedule. Parents must work with physicians and other healthcare professionals in such rare exceptions to find an acceptable alternative.

Keeping track of what vaccine your child needs and when is a tall order. The U.S. Centers for Disease Control and Prevention recommend 13 vaccines for all kids, many of which are spread across multiple doses. We hope that this guide will help you navigate the basics.
