10:20 a.m. Australia has no current plans to add Johnson & Johnson's one-dose coronavirus vaccine to its immunization drive, as it moves away from procuring vaccines under review over blood clots.

11:55 a.m. China's top disease control official said the country is considering mixing vaccines as a way of boosting efficacy, according to Reuters. Data shows Chinese vaccines lag behind others including Pfizer and Moderna in terms of efficacy. Giving people doses of different vaccines is one way to improve vaccines that "don't have very high rates of protection," said Gao Fu, director of the Chinese Centers for Disease Control and Prevention, without specifying whether he was referring to foreign or domestic vaccines. "Inoculation using vaccines of different technical lines is being considered," Gao told a conference in the Chinese city of Chengdu on Saturday.

8:27 a.m. Australia has abandoned a goal to vaccinate nearly all its population by the end of 2021 following advice that people under the age of 50 receive Pfizer's vaccine rather than AstraZeneca's. Australia, which had banked on AstraZeneca for the majority of its shots, had no plans for completing its vaccination program, Prime Minister Scott Morrison said in a Facebook post on Sunday.
3:50 a.m. China's failure to provide access to global health experts made the pandemic worse than it had to be, U.S. Secretary of State Anthony Blinken said on Sunday, and it was important to "get to the bottom" of the origin of the coronavirus. China did not give access to international experts or share information in real time to provide true transparency, Blinken said in an interview with American broadcaster NBC. As a result, the virus "got out of hand faster and with, I think, much more egregious results than it might otherwise," Blinken said.

At least a dozen hospitals in the capital say they had stopped testing for the coronavirus as of Friday due to a lack of kits or capacity. Hospitals are reluctant to test because they must admit people if they test positive, authorities say.
Meanwhile, the country reports 789 new cases and one death, taking the total number of infections to 31,658, with 97 deaths.
2:20 p.m. India reports a record 145,384 new COVID-19 cases and the highest number of deaths in more than five months, as it grapples with an overwhelming second-wave of infections that has forced the state of Maharashtra, where Mumbai is located, to impose a weekend lockdown.
