U.S. Health Secretary Robert F. Kennedy Jr. says the country is pulling its support from the vaccines alliance Gavi, saying the organization has “ignored the science" and “lost the public trust.” A video of Kennedy’s short speech was shown to a Gavi meeting in Brussels on Wednesday,

Gavi works to expand access to vaccines for children in some of the world’s poorest countries. Health experts say the move could have deadly consequences.

Gavi is a public-private partnership including WHO, UNICEF, the Gates Foundation, and the World Bank. It has paid for more than 1 billion children to be vaccinated through routine immunisation programmes,
