UNITED NATIONS -- Two in five schools (43 percent) around the world lacked access to basic handwashing with soap and water in 2019, a key condition for schools to be able to operate safely amid the COVID-19 pandemic, a UN report has found.

About 818 million children lacked basic handwashing facilities at their schools, which put them at increased risk of COVID-19 and other transmittable diseases, according to a report of the UN Children's Fund (UNICEF) and the World Health Organization that was released on Thursday.

CHICAGO -- An experimental vaccine, made from a mild virus genetically modified to carry a key gene from the COVID-19 virus, is effective at preventing pneumonia in mice infected with the COVID-19 virus, according to a study from Washington University School of Medicine in St. Louis.

The researchers created the experimental vaccine by genetically modifying vesicular stomatitis virus (VSV), a virus of livestock that causes only a mild, short-lived illness in people. They swapped out one gene from VSV for the gene for spike from SARS-CoV-2, the virus that causes COVID-19. The hybrid virus is called VSV-SARS-CoV-2, according to a news release posted on the university's website on Tuesday.
