California, Oregon, Washington and Hawaii health officials ask CDC, ‘prioritizing emerging technologies’, to reconsider

California and Washington asked the US Centers for Disease Control and Prevention (CDC) in May to validate a new way to test for measles – but after waiting two months, the CDC denied the request, citing “other competing priorities”, according to a letter from the West Coast Health Alliance to the CDC director, Erica Schwartz.

The letter, signed by health officials in California, Hawaii, Oregon and Washington, asks Schwartz to reconsider and validate a rapid, high-volume measles test in preparation for major outbreaks. The alliance also asked the CDC to create protocols to test for other high-priority pathogens to prepare for future outbreaks.

Agency declines to reveal in which state latest measles death occurred as it delays reporting other measles deaths

The US Centers for Disease Control and Prevention (CDC) added a third measles death to its dashboard on Wednesday, but the agency would not reveal whether the death occurred in Pennsylvania or another state – which is “notable” as the agency delays reporting other measles deaths, experts say.

The CDC cited privacy laws in not sharing the name of the state, but experts say there are no privacy concerns in doing so – and this information is important for the public to have as the outbreak continues accelerating, growing by 8% in one week to 4,410 confirmed cases so far this year, nearly double last year’s count.

Hepatitis B study in Guinea-Bissau that was to be funded by CDC and that drew global backlash ‘will not move forward’

The US-backed hepatitis B vaccine trial in African newborns that drew global backlash was halted, the lead researcher said on Wednesday.

It was “now clear” that the study “will not move forward in Guinea-Bissau”, Frederik Schaltz-Buchholzer, a Danish researcher, wrote on LinkedIn, adding, “we were not given the necessary governmental approval.”

Police seize doses of hepatitis B vaccine from people at center of dispute over research on African newborns

Controversial vaccine researchers who have been praised by Robert F Kennedy Jr, the US Department of Health and Human Services (HHS) secretary, had their offices in Guinea-Bissau raided by judicial police, who seized doses of hepatitis B vaccines, officials said on Facebook.

The researchers have been at the heart of an ongoing dispute over research on African newborns, supported by $1.6m from the US Centers for Disease Control and Prevention (CDC) and matched by the Pershing Square Foundation and the Bluebell Foundation for a total of $3.2m.
