Two days after initially downplaying the outbreak as “not unusual,” the US health secretary, Robert F Kennedy Jr, on Friday said he recognizes the serious impact of the ongoing measles epidemic in Texas – in which a child died recently – and said the government is providing resources, including protective vaccines.

“Ending the measles outbreak is a top priority for me and my extraordinary team,” Kennedy – an avowed anti-vaccine conspiracy theorist who for years has sown doubts about the safety and efficacy of vaccines – said in a post on X.

Kennedy said his federal Department of Health and Human Services would send Texas 2,000 doses of the measles, mumps and rubella vaccine – typically meant to be given to children in a series of two shots at 12 to 15 months old as well as between the ages of four and six years old – through its immunization program.
