Staff and essential caregivers in long-term care homes, high-risk retirement homes and First Nations elder care homes.

Alternative level of care patients in hospitals who have a confirmed admission to a long-term care home, retirement home or other congregate care home for seniors.

Highest-priority health-care workers - such as paramedics and staff in critical care units, emergency departments and COVID-19 medical units - followed by very high priority health-care workers - such as those in surgical care, obstetrics, assisted living facilities and palliative care settings.

The province also laid out intervals for when to administer the second dose of the Pfizer-BioNTech vaccine. Britain aims to offer all adults their first dose by autumn.

"This includes work underway to make vaccinations available to First Nations elder care homes across the province". The number of centres where vaccination was carried out on Friday stood at 257, with a turnout of about 57 per cent, as over 14,800 people received Covid-19 vaccine shots in Delhi on the fourth week of the inoculation drive.

This phase, officials noted, will also see the vaccination of people above 65 and those whose immunity is weak and is likely to easily be compromised like those with cancer, diabetes, HIV and other serious diseases.

A source at the health ministry, speaking on condition of anonymity, said vaccinations had begun on Thursday.

Those healthcare workers who had taken the first dose of the vaccine 28 days ago were given the second shot on Saturday, state immunisation officer Dr Rajendra Borkar said.

South Korea said on Monday it will not use AstraZeneca's coronavirus vaccine on people aged 65 and older, reversing an earlier decision, and scaled back initial vaccination targets due to delayed shipments from global vaccine-sharing scheme COVAX. "More details will be provided in the near future", she said.

This directive comes after the head of Ontario's COVID-19 vaccine task force admitted that hospitals gave some doses of the vaccine to non-frontline staff, including people working from home, because it was better to do that than to let the doses expire when people did not show up for their shot. But now we only have 20 or so places where people can get the vaccines.

"The big addition here is really for people who are aged 80 and older who are community dwelling. I think that's the biggest key addition", Bogoch said. "But expanding the program well beyond them will provide tremendous good".
