HIV: Trump says he will ask Congress to commit to eliminating HIV in the U.S. within 10 years. In the past, the president has proposed cuts to NIH, NSF and other research funding. He also eliminated the White House's advisory panel on the AIDS epidemic.
Drug prices: “As a result of my administration's efforts, in 2018, drug prices experienced their single largest decline in 46 years.” Trump has proposed significant policies that could help curb spending on prescription drugs. But none of them have taken effect yet.
