Coronavirus updates: 84% of California population to go on lockdown Sunday night

The NBA and NBA Players Association announced the first results of coronavirus testing among players in the lead-up to its shortened season starting later this month.

The league and union said 48 of the 546 players tested, roughly 8.8%, had positive results. Any player who tested positive will be quarantined away from teammates as training camps begin to open.

In March the NBA became the first American professional sports league to suspend its season after a player on the Utah Jazz contracted the virus. The suspension of the season, and eventual cancellation, started a domino effect among sports across the country. Games restarted in July under a "bubble" at Orlando's Wide World of Sports Complex. The Los Angeles Lakers won the title in October.

The 2020-2021 season is slated to begin Dec. 22 and will not take place in a "bubble."

Moderna announced in a filing with the federal government that it will begin recruiting volunteers between 12 and 18 years old to participate in its coronavirus vaccine trials.

This listing doesn't say when Moderna will start its trials in children.

It's common in clinical trials to start with adults and then when the safety profile has been established to add more populations like children and pregnant women.

Pfizer has already started recruiting, enrolling and testing its vaccine on children as young as 12 years old.

Texas Gov. Greg Abbott said the CDC is allocating over 1.4 million vaccine doses for the state for December.

The doses are expected to arrive the week of Dec. 14, he said Wednesday.

"Additional allotments may be made later this month for December," Abbott said, and "increased allotments are expected in January and the following months."

Meanwhile, California Gov. Gavin Newsom said his state will receive 327,000 doses of the Pfizer vaccine in mid-December.

New York Gov. Andrew Cuomo said Wednesday he expects the state to receive 170,000 doses of Pfizer's vaccine on Dec. 15 if all safety and efficacy approvals are granted. Cuomo said he expects additional doses of Pfizer's vaccine as well as initial allocations of Moderna's vaccine, if approved, later this month.
