In 1962, the childhood vaccination schedule consisted of 5 vaccines in 3 shots;
OPV (Oral Polio Vaccine), Smallpox, and DTP (Diphtheria-Tetanus-Pertussis) 
the first trivalent vaccine administered to children.

The 1962 Childhood Vaccine Schedule in the United States was much simpler than today’s. At that time, only a few vaccines were routinely given to children, primarily targeting diseases that had high mortality or serious complications.

1962 U.S. Childhood Vaccine Schedule (Typical)
1. DTP (Diphtheria, Tetanus, Pertussis)
Introduced: 1940s (combined vaccine)

Schedule:

1st dose: 2 months

2nd dose: 4 months

3rd dose: 6 months

Boosters: 18 months and 4–6 years

2. Polio (Oral Polio Vaccine - OPV)
Introduced: OPV in 1961 (IPV was available in 1955)

Schedule:

1st dose: around 2 months

2nd dose: 4 months

3rd dose: 6–18 months

Booster: 4–6 years

Note: In 1962, the U.S. was transitioning from IPV (Salk) to OPV (Sabin).

3. Smallpox Vaccine
Introduced: 1800s; part of routine immunization until the 1970s

Schedule:

Typically given once, around 12 months of age

Booster at school entry or later

Vaccines Not Yet in Use in 1962
The following vaccines were not part of the 1962 schedule, as they had not yet been developed or approved:

MMR (Measles, Mumps, Rubella) – introduced in 1971

Hib (Haemophilus influenzae type b) – introduced in late 1980s

Hepatitis B – introduced in 1981

Varicella (Chickenpox) – introduced in 1995

Pneumococcal, Rotavirus, Hep A, HPV, Meningococcal – introduced in 1990s–2000s

Total Number of Vaccine Doses (1962)

• About 5–10 doses total across early childhood.

Compare that to 50+ doses by age 6 in the modern schedule.
