An comprehensive overhaul of US childhood vaccination guidelines has led to a reduction in the number of routinely recommended vaccines from 17 to 11.

The freshly released list from the CDC retains core shots for diseases like polio and measles. However, others, including hepatitis A and B and coronavirus immunizations, are now categorized based on individual risk factors and subject to "joint clinical decision-making" involving doctors and parents.

"The revised recommendation is risky and needless," criticized the American Academy of Pediatrics, describing the policy.

This far-reaching guideline change represents the latest major move undertaken under the current administration by HHS Secretary Robert F. Kennedy Jr.

Government Rationale and Global Alignment

Kennedy claimed the revision followed "after an exhaustive analysis" and "safeguards children, honors families, and restores trust in the health system."

"We are aligning the American pediatric immunization calendar with global consensus while strengthening openness and informed consent," he added.

According to the statement, the new core schedule for all minors will cover vaccines for:

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

3 Tiers of Guidance

The revised framework establishes 3 distinct categories of vaccine guidance:

1. Universal Vaccines: The eleven shots mentioned above are recommended for all youngsters.
2. Risk-Based Recommendations: This group contains shots for respiratory syncytial virus, Hep A, Hep B, dengue fever, and meningococcal strains (ACWY and B). These are suggested based on a child's individual risk factors.
3. Optional Vaccines: Immunizations for Covid-19, the flu, and rotavirus are now left to discretionary discussion and choice between families and their doctors.

For the time being, health insurance will still cover vaccines that are currently on the schedule until the close of 2025.

Global Perspective and Prior Debate

The health agency performed a comparison of existing pediatric recommendations with those of twenty other developed nations. It found the US was "an international exception" in both the number of illnesses targeted and the amount of shots administered, the Department of Health and Human Services said.

This recent announcement comes weeks following a separate advisory panel adjusted the timing for the first hepatitis B vaccine. Formerly, a first dose was advised for newborns within a day of birth. Updated rules last winter shifted that to 60 days post birth if the mother tested negative for the virus.

That prior change was widely criticised by paediatricians, with the AAP describing it "a risky step that will hurt children."
