UK regulators granted emergency authorization for a vaccine made by US pharma giant Pfizer and its German partner BioNTech. The companies published data last month that showed it was 95% effective with no serious safety concerns.
The UK health secretary said 800,000 doses would be available by next week. Elderly people in care homes, along with health workers and other vulnerable people, will be top of the priority list. Pfizer CEO Albert Bourla called the UK approval "a historic moment in the fight against Covid-19."
The news of the UK authorization might cause a bit of a stir in the US. Food and Drug Administration Commissioner Stephen Hahn was summoned into the White House yesterday after President Donald Trump privately demanded to know why the agency hasn't yet approved the Pfizer vaccine.
Hahn told ABC that he believes the agency will come up with a decision relatively quickly after its December 10 committee meeting. The first shipments of Pfizer's coronavirus vaccine will be delivered on December 15, according to an Operation Warp Speed document obtained by CNN.
An advisory panel to the Centers for Disease Control and Prevention recommended that health care and long-term care workers get inoculated first as vaccines are rolled out.
YOU ASKED. WE ANSWERED
Q: If vaccines prevent people from getting sick with coronavirus, can they also prevent people from carrying the virus and infecting others?
A: "So far, we can't say for sure," CNN Chief Medical Correspondent Dr. Sanjay Gupta said.
The vaccines from Pfizer/BioNTech and from Moderna have shown high effectiveness in preventing people from getting sick with Covid-19. But the data hasn't shown whether the vaccines can prevent people from carrying the virus and infecting others.

WHAT'S IMPORTANT TODAY
CDC will decrease coronavirus quarantine time
The CDC will soon issue new guidelines reducing the number of days people should quarantine following exposure to a Covid-19 positive individual from 14 days to 7-10 days, two senior administration officials told CNN.
The new guidelines will recommend that close contacts of those infected with the coronavirus can end their quarantine after seven days if they receive a negative test, or 10 days without getting tested.
China ready to deliver millions of vaccines to countries globally
From cold-chain warehouses to temperature-controlled compartments in cargo jets, China is gearing up to send hundreds of millions of doses of coronavirus vaccines to countries that have conducted last-stage trials for its leading candidates. Chinese leaders have also promised a growing list of developing countries priority access to its successful vaccines.
The country currently has five candidates from four companies which have reached phase 3 clinical trials, the last and most important step of testing before regulatory approval is sought. David Culver and Nectar Gan report.
