Florida files lawsuit against Biden administration over vaccine mandate for federal contractors
Florida Gov. Ron DeSantis said the state has filed a lawsuit against the Biden administration, arguing that the vaccine mandate for federal contractors is "unconstitutional."
"Florida companies, public and private, receive millions of dollars in federal contracts annually and will be negatively impacted by the unlawful requirements," a statement from Florida Attorney General Ashley Moody said.
DeSantis said in a statement, "The federal government is exceeding their power and it is important for us to take a stand because in Florida we believe these are choices based on individual circumstances.”
Global cases, deaths on the rise for 1st time in 2 months
The global number of COVID-19 cases and deaths are now increasing for the first time in two months, largely driven by an ongoing rise in Europe that outweighs declines in other regions, W.H.O. Director-General Dr. Tedros Adhanom Ghebreyesus said Thursday.
The highest case increases in the last two weeks were in the Czech Republic (up by 234%), Hungary (up by 200%) and Poland (up by 183%), according to the W.H.O.
The director-general attributed ongoing infections "in large part" to inequitable access to tests and vaccines.
"Eighty-times more tests, and 30 times more vaccines, have been administered in high-income countries than low-income countries," Tedros said. "If the 6.8 billion vaccine doses administered globally so far had been distributed equitably, we would have reached our 40% target in every country by now."

Being vaccinated offers better protection than being infected: CDC study
A new study from the CDC finds that people with "natural" immunity through infection were more than five times more likely to become infected with COVID-19 compared to people who were fully vaccinated.
The study reviewed more than 7,000 people across nine states, measuring infections and hospitalization rates three to six months after either vaccination or initial infection. The study -- published in the CDC's weekly journal, the MMWR -- reaffirms prior research indicating that vaccines offer superior protection than natural immunity.
