The election of President Donald Trump raised grave concerns for the future of vaccination in the United States. Trump had frequently embraced-both before and during his election campaign-baseless and discredited allegations linking childhood vaccines to autism.(1) Shortly before his inauguration, he met with Robert F. Kennedy Jr, one of the most prominent and vocal critics of vaccine safety and current US vaccine policy, who announced after that meeting that he would lead a presidential "vaccine safety commission" charged with investigating these topics...

In the United States, groups advocating for and against abortion rights often deploy public health arguments to advance their positions. Recently, these arguments have evolved into state laws that use the government health department infrastructure to increase law enforcement and regulatory activities around abortion. Many major medical and public health associations oppose these new laws because they are not evidence-based and do not protect women's health. Yet state health departments have been defending these laws in court...

Never in its history has the nation's family planning safety net been in such jeopardy as it is today. The policy agendas of the Trump administration, Congress, and many states are being shaped by leaders adamant in their ideological opposition to-and intent to dismantle-the funding streams and providers that have long constituted the US publicly funded family planning effort.
