A pandemic of the novel coronavirus has now killed more than 1.3 million people worldwide.
Over 58.7 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks. The criteria for diagnosis -- through clinical means or a lab test -- has also varied from country to country.
The United States is the worst-affected nation, with more than 12.2 million diagnosed cases and at least 256,783 deaths.
Nearly 200 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least 10 of which are in crucial phase three studies. Of those 10 potential vaccines in late-stage trials, there are currently five that will be available in the United States if approved.
Toronto moves into lockdown status
Toronto, the largest city in Canada, is moving into lockdown -- its highest alert, what it calls grey status -- as it tries to mitigate an increasing coronavirus emergency.
The Peel Region, just west of Toronto and including Mississauga, will also be placed in the grey status.
As part of the designation, public or social indoor gatherings are not allowed. Weddings, funerals or religious services may have up to 10 people indoors. All outdoor gatherings cannot include more than 10 people.
Also, restaurants and bars may have no indoor or outdoor service though takeout is permitted. Essential retail, like pharmacies and grocery stores, can open, but at 50% capacity. All other retail is closed except for curbside pickup.
Casinos, movie theaters and museums will all be closed. Media production facilities, including Toronto's thriving film industry, can only operate with proper social distancing on set.
Cases in Toronto have gradually increased since maintaining a seven-day average of under 100 per day through most of August. The city reported a one-day high of 1,581 cases on Nov. 14 and the seven-day average reported Friday was 1,373 per day.

FDA to review Pfizer vaccine on Dec. 10
The U.S. Food and Drug Administration announced Thursday that its vaccine advisory committee will meet Dec. 10 to discuss the request for emergency use authorization of Pfizer's COVID-19 vaccine candidate.
The public meeting will be a chance for both FDA career scientists and members of the independent advisory board to ask Pfizer questions about its product.
After that, the board will make a recommendation, which the FDA will take into account when it decides whether to authorize the vaccine.
Officials said they cannot predict how long the FDA's review will take, but that it will be "as expeditiously as possible, while still doing so in a thorough and science-based manner."
