The UK Health Security Agency has identified a new recombinant strain of mpox (formerly monkeypox) that contains elements of clade Ib and clade IIb of the virus, in a traveler who recently returned from Asia.
The RNA-based Nipah virus, which causes acute respiratory illness and fatal encephalitis, can be transmitted from fruit bats to humans directly or indirectly via pigs or horses. Researchers at Wuhan Institute of Virology, Chinese Academy of Sciences and collaborators wondered whether their oral nucleoside prodrug VV-116, recently licensed against human coronaviruses such as SARS-CoV-2 in China, would be effective against Nipah virus.
Mirum Pharmaceuticals Inc. is buying privately held Bluejay Therapeutics Inc., an $820 million purchase that will bring it Bluejay’s lead asset, brelovitug, for treating chronic hepatitis D virus.
Individual liberty and choice vs. wider public health became one predictable hinge upon which swung the often-acerbic debates at the CDC’s Advisory Committee for Immunization Practices (ACIP) meeting, which took up – again – the matter of hepatitis B virus (HBV) vaccine scheduling, a day after the panel voted not to vote on such guidance.
Disorganization resulting from last-minute changes to voting questions involving new recommendations for hepatitis B virus vaccines created a moment of déjà vu Dec. 4 when the CDC’s Advisory Committee for Immunization Practices (ACIP) voted 6-3 to once again delay its votes on whether the current recommended birth dose should be pushed back.
“Do not take us backwards,” many doctors and other stakeholders implored the CDC’s Advisory Committee for Immunization Practices ahead of its meeting that starts Dec. 4 with a day-long discussion and votes on whether the current recommended birth dose of the hepatitis B virus vaccine should be delayed.
U.S. Health and Human Services Secretary Robert Kennedy continued his last-minute musical chairs ahead of the Dec. 4-5 meeting of the Advisory Committee for Immunization Practices (ACIP) when he named Kirk Milhoan as the new chair of the panel that advises the CDC on vaccine schedules.
2025 has been the most challenging year in the efforts to fight HIV since at least the advent of antiretroviral therapy. In a report on “Overcoming disruption, transforming the AIDS response,” released last week ahead of World AIDS Day on Dec. 1, the Joint United Nations Program on HIV/AIDS (UNAIDS) described “a global system in shock” by sharply reduced funding from the U.S. and other wealthy nations. Scientifically, for now, progress is ongoing.
Both the FDA and the CDC’s Advisory Committee for Immunization Practices are on the threshold of revising how vaccines are approved and used in the U.S., but whether that opens to a precipice or a new era of stronger evidence and safer use is in the telling of the beholder.
