Anti-vaxxers are spreading conspiracy theories after two recent measles-associated deaths in Pennsylvania

Anti-vaccine activists are trying to track down the families of two people, including at least one newborn, who died after contracting measles in Pennsylvania, as Governor Josh Shapiro tangles with Robert F Kennedy Jr over his “inaccurate and misleading claims”.

Kennedy, the secretary of the US Department of Health and Human Services (HHS), suggested late on Wednesday that the deaths in the state may have been “fabricated” after a Republican coroner – an elected political office in Lancaster county – claimed one of the measles-associated deaths was unrelated to the virus, although the given cause would be consistent with measles.

Newly obtained records indicate health secretary lied about Samoa trip during Senate confirmation hearings last year

A senior Democratic senator is calling for a criminal investigation into the US health secretary, Robert F Kennedy Jr, following reporting by the Guardian that indicated he lied during Senate confirmation hearings last year.

Ron Wyden of Oregon said: “RFK’s platform is built on lies and grifts that leave a trail of dead children in their wake. There are consequences for lying to Congress.”

Letters obtained by Guardian and AP contradict testimony that 2019 visit to Samoa had ‘nothing to do with vaccines’

Newly obtained documents indicate that the US health secretary, Robert F Kennedy Jr, lied during two congressional hearings last year, when he told lawmakers who held the key to his confirmation that a 2019 visit to Samoa had “nothing to do with vaccines”.

Letters obtained by the Guardian and the Associated Press contradict that testimony. In one he wrote to the Samoan prime minister before the trip, Kennedy explicitly said he wanted to study the measles, mumps and rubella (MMR) vaccine in the Pacific island nation. In it, he used the words “vaccine” or “vaccination” eight times.
