LONDON (AP) — U.S. Health Secretary Robert F. Kennedy Jr. says the country is ending support for the vaccine alliance Gavi. Speaking at a Gavi meeting in Brussels on Wednesday, Kennedy criticized the organization for “ignoring science” and losing public trust. He expressed concerns about Gavi’s collaboration with the World Health Organization during the COVID-19 pandemic, accusing them of stifling free speech. Kennedy also questioned Gavi’s vaccine recommendations, including immunizing pregnant women and funding vaccines in poorer countries. Gavi defended its decisions, citing WHO guidance and the role of vaccines in reducing childhood mortality. The U.S. has contributed $8 billion to Gavi since 2001.
