Chapter 1

Today, a child receives 50 doses of 14 vaccines by the age of 6, and 69 doses of 16 vaccines by the age of 18.

As parents, we never received as many vaccines as our children receive today. If you were born in the 1960’s or 1970’s you received around half as much.

The Math

Is the math right? You can check. Here is the calculation:

VaccineNumber of DosesCountNumber of individual vaccinesNote
Hep B313
Hib4143 or 4 recommended
PCV 13414
Hep A212
HPV3132 or 3 recommended
Total 6969

For example, since the MMR vaccine is actually 3 vaccines in one (measles, mumps, rubella), it is counted as 3 under the “Count” column. The number of individual vaccines is simply the number of doses multiplied by the “count”. So, in this example two doses of MMR equals 6 individual vaccines.

CDC Schedule

This is the schedule from the CDC website.

Additional information about each vaccine is available here.


The video did not discuss antigens. Antigens are a foreign substance which induces an immune response in the body, especially the production of antibodies. The CDC says,

“A child who receives all the recommended vaccines in the 2018 childhood immunization schedule may be exposed to up to 320 antigens through vaccination by the age of 2.”
