An Idaho mother who publicly blamed routine childhood vaccinations for the deaths of her 18-month-old twins has now been charged with murdering them, more than a year after the children were found dead in their home.
Andrea Shaw, 23, was indicted by a Payette County grand jury on two counts of first-degree murder in connection with the deaths of her twins, Dallas and Tyson Shaw. Authorities arrested her in Boise on June 30, and she is awaiting trial after being extradited to Payette County.
The case has drawn national attention because, shortly after the children's deaths in May 2025, Shaw and her husband appeared on a podcast produced by Children's Health Defense, the anti-vaccine organization founded by Robert F. Kennedy Jr., now the U.S. secretary of Health and Human Services.
During the interview, Shaw claimed the twins became gravely ill after receiving their recommended 18-month immunizations, including the DTaP, hepatitis A and influenza vaccines. She alleged the children developed fatigue, blue lips and other symptoms before they died several days later.
The family's claims became part of a broader campaign by Children's Health Defense questioning vaccine safety. The organization also supported litigation alleging the twins' deaths were caused by their vaccinations.
However, after a year-long criminal investigation, prosecutors concluded there was sufficient evidence to seek murder charges against Shaw. Police have not publicly disclosed the evidence presented to the grand jury or officially announced the children's cause of death. Court documents cited by several media outlets indicate investigators allege the twins died by suffocation, though prosecutors have not publicly detailed the evidence supporting that allegation.
Shaw's attorney, Joe Filicetti, continues to maintain that the children died from complications following their vaccinations rather than from criminal acts. He told Idaho television station KTVB that Shaw repeatedly sought medical care for the twins in the days before they died and questioned why prosecutors pursued first-degree murder charges.
Medical authorities have consistently rejected claims that routine childhood vaccines cause sudden deaths in healthy children. Extensive research conducted over decades has found no evidence that recommended vaccines cause autism or are responsible for unexplained child deaths. U.S. health agencies continue to recommend childhood immunizations because they prevent potentially fatal diseases.
The case has also renewed scrutiny of misinformation surrounding vaccines and the role of organizations that amplify unsupported medical claims. Shaw's allegations were widely circulated in anti-vaccine circles before her arrest, making the criminal charges particularly notable.
Shaw has not entered a public plea on the charges. If convicted of first-degree murder, she could face life in prison under Idaho law. The prosecution is expected to present its evidence as the case moves through the state's court system
