New Jersey enacts new law to protect vaccine access, clarifying guidance and ensuring free coverage

New Jersey has made a clean break from federal vaccine guidance, signing legislation in January 2026 that locks in science-based immunization rules at the state level. Outgoing Gov. Phil Murphy signed S4894 into law on January 18-20, days before leaving office, after the federal government quietly removed six vaccines — including Hepatitis B, Influenza, and COVID-19 — from the routine childhood schedule NJ.gov.
The move came after Acting CDC Director Jim O'Neill issued a memorandum on January 5, 2026, cutting the number of routinely targeted diseases from 17 down to 11 KFF. New Jersey refused to follow. The new law requires state health insurers to cover all recommended vaccines with zero out-of-pocket costs, no matter what Washington decides Burlington County Times.
For years, New Jersey tied its vaccine rules to the federal Advisory Committee on Immunization Practices, known as ACIP. That worked fine — until it didn't. In late 2025, HHS Secretary Robert F. Kennedy Jr. began overhauling the federal childhood schedule, describing the changes as a push for "flexibility and choice, with less coercion" AAMC. By January 2026, six vaccines had been reclassified from "routine" to "shared clinical decision-making" — meaning doctors would decide case by case, rather than vaccinating all children.
New Jersey health officials said the federal shift was made without meaningful input from the broader medical community. Acting Health Commissioner Jeff Brown said federal actions had caused "major harm" and that the new state law ensures policy is guided by "the best available science" NJ Spotlight News. The state now anchors its guidance to groups like the American Academy of Pediatrics instead of ACIP.
The law has two clear effects. First, it locks in New Jersey's own vaccine recommendations, based on leading medical bodies, not federal politics. Second, it requires all state-regulated insurers and the NJ Medicaid program — called NJ FamilyCare — to cover those vaccines for free NJ.gov. No copays. No surprise bills. If a vaccine is on the state list, it is covered.
Sponsor Senator Joe Vitale argued that New Jersey must not be "dependent on abrupt changes" at the federal level that "undermine confidence in immunizations" NJ Herald. The bill passed the Senate 25-12 on December 22, 2025, and the Assembly 51-24 on January 12, 2026, according to LegiScan.
Before the law, New Jersey providers faced a tricky problem. If the federal government removed a vaccine from its routine list, insurers could deny coverage and providers could face billing disputes. The new law closes that gap. Pharmacists and pediatricians can now administer and bill for all state-listed vaccines under standing state orders, protecting them from financial and legal confusion NJBIA.
The American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists all backed the law. They warned that the federal schedule cuts risked a "dangerous reduction" in vaccination rates and would leave parents deeply confused about what their children actually need My Central Jersey.
New Jersey is not alone. Fifteen states have already filed lawsuits against the federal government over the new vaccine schedule, according to AAMC. New Jersey has also joined a Northeast Public Health Alliance — a regional bloc working to create a shared firewall against federal policy swings. Murphy said the federal government had "diverged and waffled on evidence-based recommendations... putting our most vulnerable residents at risk" NJ.gov.
Critics, including several NJ Republican senators and advocacy groups like the Weston A. Price Foundation, called the law a government overreach. They argued it expands state power to mandate vaccines without federal oversight and limits parental choice North Jersey. But with new Governor Mikie Sherrill sworn in on January 20 and a 14-point election win behind her, public health advocates say the political ground in New Jersey is firm.
