OTTAWA, Nov. 5 (Xinhua) -- Canadians under the age of 12 now account for over 20 percent of daily new cases of COVID-19, the Public Health Agency of Canada (PHAC) said Friday.

Canadians under 12 represent 12 percent of the country's population of 38 million. There are about 4.3 million children under 12 who are not vaccinated in the country.

The overrepresentation is not unexpected, given the high level of vaccination in other age groups, Canada's Chief Public Health Officer Theresa Tam said at a press conference in Ottawa on Friday.

Canada has ordered 2.9 million doses of Pfizer's vaccine for children. It is still waiting for approval from the Canadian Health Ministry.

More than 58.9 million doses of COVID-19 vaccines have been administered across Canada since vaccination began last December, according to the latest data from PHAC.

This means over 89 percent of the eligible population -- those 12 and older -- have received at least one shot, while more than 84 percent of eligible Canadians are fully vaccinated.

The latest PHAC data shows 4 million people have not yet received a single dose, while 1.5 million people are only partially vaccinated. There have been some outbreaks in schools and daycares in Canada. Tam said they have generally been small in size.
