The Trump administration’s proposed budget eliminates funding for programs that provide lifesaving vaccines around the world, including immunizations for polio. Trump proposes to eliminate the CDC and Prevention’s global health unit, effectively shutting down its $230 million immunization program: $180 million for polio eradication and the rest for measles and other vaccine-preventable diseases. Trump also withdraws financial support for Gavi, the international vaccine alliance that purchases vaccines for children in developing countries.
