A person will receive a minimum of 100 vaccines in their lifetime beginning when birth. Between birth and the age of six years, your child will have 28 vaccinations most of them are first shots and boosters and a yearly influenza vaccine which would bring the total to 34. For children and young adults ages 7 to 18 there are shots suggested but not required at age 11 or 12 they should have a DTaP booster, the two-shot series of HPV, and a meningitis vaccine.
At age 16 to 18 they should have a meningitis booster. If this group receives the shots, they will have a total of five more shots for that age group plus a yearly flu shot which would be seven more immunizations totaling 12 more shots for that age group. For ages 19 through 65+ years you should have your annual influenza vaccine, a Tdap every 10 years, a zoster vaccine which is a two-shot series, the pneumonia vaccine which is a two-shot series, and several other that would depend on when you were born and if you did not have certain vaccines previous to this age group.
The total for this group would be approximately 50 flu shots, and the other shots would total four so that would be 54 shots. So, we have 34+12+54=100, and this would be dependent upon someone from birth to 65 taking every immunization, whether it was mandatory or not.
