British Columbia is extending the time between first and second doses of three differentCOVID-19 vaccines to four months a decision that amounts to a "population-level experiment," according to Canada's chief science adviser, Mona Nemer.

The government says it expects the change, and Health Canada's recent approval of a third vaccine, to result in every eligible person in B.C. receiving the first dose of their vaccine by mid- to late July. The two-dose vaccine from Oxford University and AstraZeneca was approvedlate last week.

"This gives us a very real and important benefit to everybody here in B.C.," said Dr. Bonnie Henry, B.C.'s provincial health officer.

"That means we can move everybody up the list and more people will be protected sooner."

Health officials announced the accelerated timeline Monday as the province moved into the second, seniors-focused phase of its vaccination campaign.

Nemertold CBC News Network'sPower & Politics that the data provided so far byModerna and Pfizer on theirvaccines was gathered when the first and second doses of the vaccines were being spaced three to four weeks apart, not three to four months apart.

"I think it's really important that we stick with the data and with the great science that give us these fantastic vaccines, and not tinker with it," she told host Vassy Kapelos.

"I think that it's possible to do it. But it amounts right now to a basically population-level experiment. And I think it needs to be done as we expect clinical trials to be carried out.

The National Advisory Committee on Immunizations (NACI) and Health Canada also appear to be at odds over whether people age65 and older should receive the AstraZeneca-Oxford vaccine.

Why Canadian committee and Health Canada differ on Oxford-AstraZeneca vaccine

Dr. Isaac Bogoch, an infectious diseases physician and member of Ontario's COVID-19 immunization task force, explains why the National Advisory Committee on Immunization is not recommending the Oxford-AstraZeneca vaccine for people 65 and older, even though Health Canada has authorized its use for adults of all ages.

Health Canada has authorized its use for adults of all ages. But theNACI, which makes recommendations to governments on the use of newly approved vaccines for humans, said Monday it does not recommend the vaccine for seniors "due to limited information on [its] efficacy" in that age group.

The NACI said its recommendations are based on independent advice and reflect the best current available scientific knowledge.

B.C. expects to receive its first shipment of the AstraZeneca-Oxfordvaccine likely 60,000 doses next week.

Alberta is also taking a step forward by moving into Step 2 of its own plan to ease COVID-19 restrictions. Premier Jason Kenney said the health-care system is seeing a sharp decline in hospital admissions. The number of cases in long-term care facilities also has declined by more than 95 per cent since a peak in December, he said.

"This is encouraging data," Kenney said told an afternoon news conference.

"And this data speaks to both the sacrifices that millions of Albertans have made, as well as the huge impact of COVID-19 vaccination since we've delivered the second dose to all the residents of those facilities."

The decision means libraries will be allowed to reopen at limited capacity, and that some low-intensity group fitness activities can resume indoors. Other reopening measures have been delayed, however, such as the easing of restrictions on retail businesses.

Dr. Deena Hinshaw, Alberta's chief medical officer of health, reported 291 new COVID-19 casesand two more deaths on Monday.

The number of new coronavirus infections rose last week for the first time in seven weeks, World Health Organization (WHO) director general Tedros Adhanom Ghebreyesus said on Monday. Tedros said the rise was "disappointing but not surprising" and urged countries not to let up in measures to fight the spread of the disease.

At the same time, Mike Ryan, WHO's top emergency expert, said the global fight against the coronavirus was in a better state now than it was 10 weeks ago before the rollouts of vaccines had begun.

In theAsia-Pacific region, thePhilippines launched a vaccination campaignon Monday but faces supply problems and public resistance, which it hopes to ease by inoculating top officials.

Cabinet officials, along with health workers and military and police personnel, were among the first to be vaccinated in six hospitals after 600,000 doses donated by China were received on Sunday.

The World Health Organization says a combination of coronavirus suppression and vaccinations could put an end to the most tragic outcomes of the pandemic, although the novel virus will not be gone altogether.

The Philippines has reported more than 576,000 infections, including 12,318 deaths, the second-highest totals in southeast Asia after Indonesia.

Aside from China's donated vaccine from Sinovac Biotech Ltd., the government has separately ordered 25 million doses from the China-based company, but no date has been set for the deliveries. Health Secretary Francisco Duque III said the delivery of an initial 525,600 doses of AstraZeneca's vaccine that was initially scheduled for Monday would be delayed by a week due to supply problems.

The government has been negotiating to secure at least 148 million doses from Western and Asian companies to vaccinate about 70 million Filipinos for free in a massive campaign funded by foreign and domestic loans.

In theAmericas,Brazil's capital has entered a two-week lockdown, joining several states in adopting measures to reduce the spread of COVID-19 as intensive care beds begin to fill in some important cities.

At least eight Brazilian states adopted curfews over the past week due to the rise in cases and deaths from COVID-19. Thursday was Brazil's deadliest day since the beginning of the pandemic, with 1,541 deaths confirmed from the virus. So far more than 254,000 people have died overall.

Brasilia Gov. Ibaneis Rocha decreed the total closure of bars, restaurants, shopping malls and schools until March 15 and prohibited gatherings of people. Sale of alcoholic beverages was prohibited after 8 p.m. In the federal district, 85 per centof hospital beds were occupied on Sunday, according to the local health ministry.

President Jair Bolsonaro again criticized such measures, saying on his Twitter account: "The people want to work." He threatened on Friday to cut off federal emergency pandemic assistance to states resorting to lockdowns.

InEurope, health officials in Britain have identified six cases of the P1 variant including one in a person who has not been traced. Direct flights from Brazil to the U.K. have been halted, but the newly identified cases have been linked to people who came to the U.K. from Brazil through other European cities in early February. The arrivals came days before the U.K. imposed a 10-day hotel quarantine on people arriving from high-risk countries, including Brazil.

Erdogan said on Monday cafs and restaurants will be allowed to reopen at half-capacity between 7a.m. and 7:30 p.m. apart from those located in 17 regions that have been categorized as "very high-risk." Nighttime curfews during weekdays will continue across Turkey as part of the government's "controlled normalization" program, he said.

Schools will reopen for face-to-face education in low- and medium-risk regions, Erdogan said. In other regions, only students preparing for high-school or university entrance exams will attend schools full-time.

InAfrica,Ivory Coast has begun giving shots to inoculate against COVID-19 with vaccines delivered last week by the global COVAX initiative, which was created to ensure that low- and middle-income countries have fair access to doses.

The West African country's mass vaccination campaign started with jabs being given to health workers, teachers and members of the armed forces in the commercial capital, Abidjan, where 95 per centof the country's cases have been recorded. According to WHO and UNICEF, some 24 other African countries are expected to start receiving vaccines via COVAX this week in what they say is the world's largest vaccine procurement and supply operation in history.

South Africa remained the hardest-hit country inAfrica, with more than 1.5 million reported cases of COVID-19 and nearly 50,000 deaths. With fewer new cases being reported, South Africa is easing some restrictions but President Cyril Ramaphosaurged people to stick with measures like physical distancing.
