An extensive revision of US pediatric immunisation protocols has resulted in a reduction in the quantity of universally advised vaccines from 17 to 11.

The freshly released list from the CDC retains core vaccines for diseases like polio and rubeola. However, several others, including liver infection vaccines and Covid vaccines, are now categorized based on individual risk factors and subject to "joint medical deliberation" between doctors and parents.

"The revised guideline is risky and needless," criticized the AAP, labeling the change.

This far-reaching guideline shift constitutes the latest significant action implemented under the current government by HHS Secretary Robert F. Kennedy Jr.

Government Justification and Global Alignment

Kennedy asserted the revision followed "after an exhaustive review" and "safeguards children, respects families, and restores trust in public health."

"This aligning the American pediatric immunization calendar with international standards while strengthening transparency and informed consent," he added.

Per the statement, the new universal schedule for all children will cover vaccines for:

• Measles, mumps, and rubella (MMR)
• Poliovirus
• DTaP/Tdap (Diphtheria, Tetanus, Pertussis)
• Haemophilus influenzae type b (Hib)
• Pneumococcus infection
• Human papillomavirus (HPV)
• Varicella (chickenpox)

Three Tiers of Recommendations

The revised structure establishes 3 distinct tiers of vaccine advice:

1. Core Vaccines: The eleven shots mentioned above are advised for every children.
2. Conditional Vaccines: This category includes vaccines for RSV, hepatitis A, Hep B, dengue fever, and meningococcal types (ACWY and B). They are recommended based on a child's individual risk factors.
3. Optional Vaccines: Immunizations for the coronavirus, influenza, and rotavirus are now left to discretionary discussion and decision by parents and their physicians.

For the time being, medical coverage will continue to pay for vaccines that are still on the schedule until the end of 2025.

International Context and Prior Debate

The health agency conducted a comparison of existing pediatric recommendations with those of 20 other developed countries. It determined the United States was "an international exception" in both the quantity of diseases covered and the number of doses administered, the HHS said.

This latest announcement comes weeks after a separate CDC panel adjusted the schedule for the initial liver infection shot. Formerly, a first dose was advised for infants within a day of birth. Updated rules last winter shifted that to two months after birth if the parent tested non-reactive for the virus.

That earlier change was roundly criticised by paediatricians, with the AAP describing it "a risky move that will hurt kids."
