Nearly 500 Los Angeles Unified School District employees were fired this week for refusing to comply with a mandate that they get vaccinated against COVID-19, while some 34,000 students have not yet been vaccinated as required.
Schools with students who have higher levels of substance use and depressed feelings have a higher prevalence of school discipline and school-based police contact, according to a study by Columbia University Mailman School of Public Health researchers.
A person in California who had been vaccinated against COVID-19 became the first in the U.S. to have an identified case of the omicron variant, the White House announced Wednesday as scientists continue to study the risks posed by the new virus strain.
After a slow start, the United States has improved its surveillance system for tracking new coronavirus variants such as omicron, boosting its capacity by tens of thousands of samples per week since early this year.
