Two Democratic senators are launching an investigation into whether Health Secretary Robert F. Kennedy Jr. lied to Congress about his reason for a 2019 trip to Samoa. The investigation comes after The Associated Press and The Guardian published documents in August refuting Kennedy's testimony. The new inquiry is one of a vast array of investigations planned into the Trump administration after Democrats regained control of the House and Senate from Republicans in the midterm elections.

Congo's Ebola outbreak has topped 11,000 cases, highlighting the severity of the situation. The health ministry reported on Wednesday 11,042 infections and 5,387 deaths, making it Congo's deadliest outbreak. The crisis began in mid-May, and authorities have struggled to contain it due to armed conflicts, a health system crisis, poor roads, and violence fueled by mistrust. The Bundibugyo virus responsible for this outbreak has no known vaccine or treatment and has spread to eight provinces. Health workers face attacks, and experts urge more efforts to contain the disease, which has spread to Uganda, Kenya, and Nigeria.

Lancaster County in Pennsylvania has been the epicenter of the nation's worst measles outbreak in 35 years. It's also home to the largest Amish population in the U.S. Some Amish and related Mennonite groups, with historically lower rates of vaccination, have been hit hard. Vaccination rates also declined in the general population amid the resurgence of a contagious virus considered “eliminated” from the U.S. since 2000. Pennsylvania leads the U.S. this year with over 1,350 cases, more than a third in Lancaster County, according to official figures. Many Amish and Mennonites are showing a new openness to vaccines, while members of the general public are also taking extra precautions.

A first-of-its-kind cancer vaccine is helping significantly reduce the chances that melanoma patients' tumors return. Drugmakers Moderna and Merck announced the results Thursday. The vaccine was custom-brewed for each patient to match their tumor. It teaches the patient’s immune system to watch out for and attack any cancer cells that start forming again. Adding it to a standard post-surgery treatment reduced by 42% the risk of melanoma returning two years after surgery, according to the most advanced study to date.
