California governor in quarantine with family after kids exposed to Covid-19
California Gov. Gavin Newsom is quarantining with his family after three of his four children were exposed to a patrol officer who tested positive for Covid-19, he said in a tweet late Sunday.

China tests millions after coronavirus flare-ups in 3 cities
BEIJING — Chinese authorities are testing millions of people, imposing lockdowns and shutting down schools after multiple locally transmitted coronavirus cases were discovered in three cities across the country last week.
As temperatures drop, large-scale measures are being enacted in the cities of Tianjin, Shanghai and Manzhouli, despite the low number of new cases compared to the United States and other countries that are seeing new waves of infections.
Many experts and government officials have warned that the chance of the virus spreading will be greater during the cold weather. Recent flare-ups have shown that there is still a risk of the virus returning, despite being largely controlled within China.
On Monday, the National Health Commission reported two new locally transmitted cases in Shanghai over the last 24 hours, bringing the total to seven since Friday. China has recorded 86,442 total cases and 4,634 deaths since the virus was first detected in the central Chinese city of Wuhan late last year.
AstraZeneca says its coronavirus vaccine can be around 90 percent effective
LONDON — British pharmaceutical giant AstraZeneca said on Monday that its vaccine for Covid-19 could be up to 90 percent effective in preventing the disease — the third promising breakthrough in the fight against a pandemic that has killed nearly 1.4 million people worldwide.
“This vaccine’s efficacy and safety confirm that it will be highly effective against Covid-19 and will have an immediate impact on this public health emergency," Pascal Soriot, Chief Executive Officer, said in a statement.
Analysis of data from a phase 3 trial of the vaccine developed by Oxford University showed that it was 90 percent effective at stopping the disease when half a dose was administered followed by a full dose. In another dosing regiment, when two full doses were administered, the vaccine was 62 percent effective, researchers said, resulting in combined average efficacy of 70 percent.
