Even looking at the CDC recommended vaccination schedule, extreme hyperbole is employed by anti-vaxxers to frighten parents. Either it's intentional misinformation or just really bad counting skills. Or maybe it's a combination of both being used to promote "fear appeal".
A few examples demonstrating that, even amongst anti-vaxxers, the number of "vaccines" they claim varies greatly.

| "74 injected vaccines by 4-6 years" |
 |
| "49 doses of 14 vaccines by age 6" |
 |
| "74 vaccines" |
 |
| "81 vaccines by 6 years of age" |
So how many vaccines does a child actually receive?
To clarify, we need to define a few terms first.
and
and
and
A injectable vaccine dose is 0.5 mL for most vaccines with one exception: the dose of influenza vaccine we give at 6 months of age and then at least a month later are 0.25 mL each. A vaccine such as DTaP, Pediarix, Proquad, or MMR - although they are polyvalent, are still 0.5 mL in a single dose.
Method one: How many actual vaccines do we use in our office?
Engerix (not actually given in our office - birth dose given at hospital)
PedVaxHiB
Prevnar 13
Rotateq
Fluzone
MMR
Varivax
Havrix
Kinrix
Proquad
Menactra
Trumenba
Gardasil
Adacel
Total: 15 actual vaccines
Method two: If we count by the number of diseases we protect against with vaccines:
Diphtheria
Tetanus
Pertussis
Polio (IPV)
Streptococcus pneumoniae (S pneumo)
Hemophilus influenza type B (HiB)
Rotavirus (rota)
Influenza (flu)
Measles
Mumps
Rubella
Varicella (Chickenpox)
Hepatitis A (Hep A)
Neisseria meningitidis ACWY (meningococcal ACWY)
Human Papilloma Virus (HPV)
Neisseria meningitidis B (meningococcal B)
Total: 17 diseases we protect against
Method three: I'm not aware of any practice that doesn't use combination vaccines but for the sake of argument, the number of injections if no combination vaccines were used for a child who receives every single possible recommended vaccine exactly on time without the availability of FluMist in my office:
Birth dose Hep B = 1 injection
2 months of age: DTaP, IPV, Hep B, Prevnar, HiB, Rotateq = 5 injections (1 oral)
4 months of age: DTaP, IPV, Hep B, Prevnar, HiB, Rotateq = 5 injections (1 oral)
6 months: DTaP, Hep B, IPV, Prevnar, influenza, Rotateq = 5 injections (1 oral)
12 months: MMR, Hepatitis A, Prevnar, influenza = 4 injections
15 months: Varivax, HiB, DTaP = 3 injections
18 months: Hepatitis A, influenza = 2 injections
3 years: influenza = 1 injection
4 years: DTaP, IPV, MMR, Varivax, influenza = 5 injections
5-10 years: influenza = 6 injections
11 years: HPV, Menactra, Tdap, influenza = 4 injections
12 years: HPV, influenza = 2 injections
13-15 years: influenza = 3 injections
16 years: Trumenba, Menactra, influenza = 3 injections
17 years: Trumenba, influenza = 2 injections
18 years: influenza =1 injection
Total: 32 injections by age 6 if no combination vaccines are used (29 injections if we use FluMist)
52 injections by age 18 if no combination vaccines are used (33 injections if we use FluMist)
Method four: Number of actual injections given to a child who receives every single possible recommended vaccine exactly on time without the availability of FluMist in my office (including birth dose of hepatitis B that we don't actually give in our office)
Birth dose Hep B = 1 injection
2 and 4 months of age: Pediarix, Prevnar, HiB, Rotateq = 6 injections (2 oral)
6 months of age: Pediarix, Prevnar, Rotateq, influenza in the winter = 3 injections (1 oral)
12 months: MMR, Hepatitis A, Prevnar, influenza = 4 injections
15 months: Varivax, HiB, DTaP = 3 injections
18 months: Hepatitis A, influenza = 2 injections
3 years: influenza = 1 injection
4 years: Kinrix, MMRV, influenza = 3 injections
5-10 years: influenza = 6 injections
11 years: HPV, Menactra, Tdap, influenza = 4 injections
12 years: HPV, influenza = 2 injections
13-15 years: influenza = 3 injections
16 years: Trumenba, Menactra, influenza = 3 injections
17 years: Trumenba, influenza = 2 injections
18 years: influenza =1 injection
Total: 25 injections by age 6 (with FluMist, there would be 22 injections total)
44 injections by age 18 years (with FluMist, there would be 28 injections total)
Method five: If we count by the number of doses of a vaccine with the same conditions as method four:
Total: 47 doses (44 injections + 3 oral doses) by age 18 years
Method six If we count by the number of "pathogens" with the same conditions as above:
2 and 4 months of age: Pediarix (diphtheria, tetanus, pertussis, polio, hep B), Prevnar, HiB, rota = 16
6 months of age: Pediarix (diphtheria, tetanus, pertussis, polio, hep B), Prevnar, Rotateq, influenza = 8
12 months: MMR (measles, mumps, rubella), Hepatitis A, Prevnar, influenza = 6
15 months: Varivax, HiB, DTaP (diphtheria, tetanus, pertussis) = 5
18 months: Hepatitis A, influenza = 2
3 years: influenza = 1
4 years: Kinrix (diphtheria, tetanus, pertussis, polio), MMRV (measles, mumps, rubella, varicella), influenza = 9
5-10 years: influenza = 6
11 years: HPV, men ACWY, Tdap (tetanus, diphtheria, pertussis), influenza = 6
12 years: HPV, influenza = 2
13-15 years: influenza = 3
16 years: men ACWY, men B, influenza = 3
17 years: men B, influenza = 2
18 years: influenza =1
Total: 72 "pathogens" by age 18 (many of which are the same pathogen)
Method seven: include all the "pathogens" in method six and also throw in the maternal doses of influenza and Tdap (tetanus, diphtheria, pertussis):
Total number of "pathogens": 76 "pathogens" by age 18
Method eight: include all of the "valences" or strains covered in method six:
birth dose hep B : 1 valence or strain
2 and 4 months of age: Pediarix (diphtheria, tetanus, pertussis, polio, hep B), Prevnar (13 strains), HiB, rotateq (5 strains) = 48
6 months of age: Pediarix (diphtheria, tetanus, pertussis, polio, hep B), Prevnar (13 strains), Rotateq (5 strains), influenza (4 strains) = 27
12 months: MMR (measles, mumps, rubella), Hepatitis A, Prevnar (13 strains), influenza (4 strains) = 21
15 months: Varivax, HiB, DTaP (diphtheria, tetanus, pertussis) = 5
18 months: Hepatitis A, influenza (4 strains) = 5
3 years: influenza (4 strains) = 4
4 years: Kinrix (diphtheria, tetanus, pertussis, polio), MMRV (measles, mumps, rubella, varicella), influenza (4 strains) = 12
5-10 years: influenza (4 strains) = 24
11 years: HPV (9 strains), Neisseria meningitidis ACWY( 4 strains), Tdap (tetanus, diphtheria, pertussis), influenza (4 strains) = 20
12 years: HPV (9 strains), influenza (4 strains) = 13
13-15 years: influenza (4 strains) = 12
16 years: men ACWY (4 strains), men B, influenza (4 strains) = 8
17 years: men B, influenza (4 strains) = 5
18 years: influenza (4 strains) =4
Total: 209 valences or strains by age 18 (many of which are the same strains)
So, in summary:
- "74 injected vaccines by age 4-6"?
False. By age 6, a child in my office receives, at the most, 25 injections (22 if we use FluMist)
- "49 doses of 14 vaccines by age 6"?
False. By age 6, a child in my office receives, at the most, 28 doses of 11 vaccines.
- "81 vaccines by 6 years of age"?
False. By the age of 6, a child in my office receives, at the most, 25 injections or 28 doses of 11 vaccines
- "69 doses of 16 vaccines by age 18"?
False. By the age of 18, a child in my office receives, at the most, 47 doses of 15 vaccines.
I suppose if you're going to accurately exaggerate what vaccines do, the claim would be 209 valences/strains by age 18 but that just doesn't sound nearly as scary. The take home message here is that we have the ability to protect against 17 different diseases that cause significant harm and we can do so safely and effectively.
