In
another attempt to change the childhood vaccine schedule, President Donald
Trump signed an executive
order
on Friday to direct the Centers for Disease Control and Prevention (CDC) and
its Advisory Committee on Immunization Practices (ACIP) to review the assessment issued by the U.S.
Department of Health and Human Services (HHS) earlier this year. In that
assessment, HHS found that the U.S. recommended more core childhood vaccines
than its peer developed nations. In January, after the assessment was released,
HHS announced changes to the childhood vaccine schedule. So far, this change has
been temporarily blocked by a federal court through a preliminary injunction
issued in March after the American Academy of Pediatrics (AAP) and other
medical organizations amended an existing lawsuit against HHS to dispute the vaccine
schedule changes.
While peer nations may have different vaccine schedules,
it is important to understand why U.S. vaccine recommendations are appropriate
for children here in the U.S. and why recommendations may differ by country.
The AAP has a fact
sheet
on its website, explaining that vaccine
recommendations are largely based on a population’s risk of exposure to a
disease and how that disease impacts health. For example, the U.S. does not
recommend routine immunization for tuberculosis, typhoid, yellow fever,
malaria, meningococcal disease (for infants), or dengue, while these are
routinely recommended in other countries. AAP also points out that certain
vaccines are not available in every country, which can lead to nuances in
vaccine schedules, especially for combination vaccines.
Last year, the Pennsylvania Department of Health (PA DOH)
released a statement on their website recommending that Pennsylvanians follow
the immunization
recommendations
issued by AAP, American Academy of Family
Physicians, and American College of Obstetricians and Gynecologists. Both
the PA State Boards of Medicine and Osteopathic
Medicine strongly support PA DOH’s endorsement of these
evidence-based immunization schedules and the recommendations of these trusted
medical organizations.
As childhood vaccine recommendations continue to be debated at a national level, patients should continue to consult their physician before making any vaccine related decisions.
