Based on new studies that are coming in all the time, ACIP will tweak the recommended vaccine schedule (adding or removing boosters), add new vaccines, suggest different schedules, etc., taking into account disease prevalence, new outbreaks, etc. 2/

This is why different countries can look at the same scientific literature on vaccines and come up with different vaccine schedules, as I discussed here. In addition, practicalities of the health care systems in different countries have an influence. 3/https://sciencebasedmedicine.org/are-recommended-childhood-vaccine-schedules-evidence-based/ …

For example, it’s important in Africa to get children fully immunized as early as is practical because they are more at risk, which might result in a different schedule because African babies aren’t available for well child visits at 2, 4, and 6 months. 4/

Basically, vaccine schedules are science- and evidence-based, but also consider threat assessment, practicalities on the ground, and sometimes cost. They are being continually revised based on new evidence and changes "on the ground" (e.g., outbreaks). 5/

Given that, it's not really possible to cite the "original" research upon which our schedule is based. That research is decades old and much is no longer relevant today, having been continually superseded year after year with new research building upon the old. 6/

In iterative processes like developing and revising the vaccine schedule year after year, in essence the requirement is to continually review and rereview the entire scientific literature on vaccines AND consider changing conditions "on the ground." 7/7
