Each year, since 1995, the Advisory Committee on Immunization Practices (ACIP) of the CDC has reviewed the recommended immunization schedule, and it has then been approved by ACIP, the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists.
Before 1995, in 1994, 1989, and 1983, an immunization schedule was simply published as part of the ACIP’s general recommendations.

The AAP published their own schedules too.
The latest schedule was updated in 2019.
Immunization Schedules
Looking for an alternative immunization schedule?
According to the American Academy of Pediatrics:
“No alternative vaccine schedules have been evaluated and found to provide better safety or efficacy than the recommended schedule, supported by the Advisory Committee on Immunization Practices of the CDC and the Committee on Infectious Diseases of the AAP (the committee that produces the Red Book).
Pediatricians who routinely recommend limiting the numbers of vaccines administered at a single visit such that vaccines are administered late are providing care that deviates from the standard evidence-based schedule recommended by these bodies.”
Countering Vaccine Hesitancy
There are no alternative immunization schedules.
