Colorado Democrats Protect Public Health, Safeguard Vaccine Recommendations Backed by Science

DENVER, CO – Colorado Democrats passed legislation this year to ensure the state’s science-backed vaccine recommendations are protected in the event that federal guidance is undermined or overhauled.

"As a health care professional, following the science is non-negotiable. Science-based decision making should never be political, but unfortunately in this day and age we’re seeing misinformation and debunked studies weaponized in order to advance a dangerous public health agenda," said Senator Kyle Mullica, D-Thornton. "That’s why this year we worked proactively to ensure that here in Colorado, we’re using well-informed recommendations about immunizations that keep our kids and communities protected. With this bill, we’re expanding CDPHE’s ability to incorporate recommendations from a broad group of trusted organizations that rely on science, not whoever happens to be in office."

"Secretary Kennedy’s circulation of medical misinformation and the promotion of false information about vaccines has left many physicians and health care experts concerned about the long-term safety of our communities," said Rep. Lindsay Gilchrist, D-Denver. "For years, I worked in the public health space, and I can say with confidence that vaccines are one of the best tools we have to fight disease and save lives. In the shadow of federal uncertainty, we stepped up to protect the health of our kids and community members, and under our law, Colorado can utilize vaccine recommendations from trusted organizations that follow the science."

"For months, physicians have been fearful about what vaccine recommendations will come down from the federal government," said Senator Lindsey Daugherty, D-Arvada. "Secretary Kennedy has been a longtime skeptic of vaccines and consistently chooses misinformation over science. Given his influence and the uncertainty in DC, we knew that we needed to take action to put science first and protect Colorado’s best interests. This legislation ensures that whatever happens federally, Colorado will continue to rely on scientific data that protects Colorado kids and builds healthier communities for us all."

"Choosing science-based information to keep our kids safe shouldn't be controversial, yet the Trump administration continues to unravel foundational health care tools trusted by doctors and public health experts," said Rep. Kyle Brown, D-Louisville. "To protect the health and safety of Coloradans, our immunization policy must be driven by science, not misinformation. Under our law, Coloradans can rest assured knowing that their vaccine recommendations are coming from organizations that rely on fact-driven, scientific information to make their decisions." 

HB25-1027, sponsored by Senators Mullica and Daugherty, and Representatives Brown and Gilchrist, updates disease control statutes to direct the Colorado Department of Public Health and Environment (CDPHE) to consider recommendations from the American Academy of Pediatrics, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the American College of Physicians, in addition to federal guidance from the Advisory Committee on Immunization Practices (ACIP). Prior to this legislation, CDPHE only considered recommendations from the ACIP.

Earlier this month, Health and Human Services Secretary Robert F. Kennedy Jr. fired every member of the ACIP, which advises the Centers for Disease Control and Prevention on the safety, efficacy and clinical needs of vaccines. The newly-appointed ACIP is currently meeting to discuss the efficacy of several vaccines including: COVID-19, RSV, and Measles, Mumps, Rubella, and Varicella (MMRV). The advisory committee is scheduled to vote tomorrow on new recommendations regarding influenza and RSV vaccines. Secretary Kennedy has repeatedly spread widely-debunked misinformation linking vaccines with autism.

HB25-1027 also aims to improve health care outcomes by expanding patient access to testing for hepatitis C, which is currently difficult for many patients to obtain. Hepatitis C cases are on the rise nationally and in Colorado.

Democrats also passed SB25-196 to protect insurance coverage for preventive health care should the existing federal protections be repealed, dismantled, or disempowered. The new law gives state insurance agencies the authority to reinstate guidelines on preventive care from federal agencies that existed in January 2025, including from the ACIP.
