COVID-19: What you need to know about the coronavirus pandemic on 11 June

Confirmed cases of COVID-19 have passed 174.8 million globally, according to Johns Hopkins University. The number of confirmed deaths stands at more than 3.77 million. More than 2.26 billion vaccination doses have been administered globally, according to Our World in Data.

Health authorities in Chile have announced a blanket lockdown across the capital Santiago following a rise in COVID-19 case numbers. The move comes despite the country having fully vaccinated more than half its population.

The United States has administered 305,687,618 doses of COVID-19 vaccines and distributed 372,830,865 doses in the country as of Thursday morning, the U.S. Centers for Disease Control and Prevention said.

Singapore will start a phased easing of its COVID-19 restrictions from next week. Steps include including allowing up to five people to gather - up from two currently.

On Friday, India reported 91,702 new COVID-19 infections over the past 24 hours, and 3,403 daily deaths from the coronavirus.

India's total COVID-19 caseload now stands at 29.3 million, while total fatalities are at 363,079.

The Philippines will exempt elderly people who have been fully vaccinated from stay-at-home orders to encourage more to get inoculated and help authorities meet COVID-19 immunisation targets, officials said on Friday.

The United States will purchase half a billion COVID-19 vaccine doses for lower-income countries, U.S. President Joe Biden said on Thursday.

"Half a billion vaccines will start to be shipped in August, as quickly as they roll off the manufacturing line," Biden said at a news conference before the G7 summit in Britain.

Biden, speaking alongside Pfizer Chief Executive Albert Bourla in the English seaside resort of Carbis Bay ahead of the G7 summit, thanked other leaders for recognising their responsibility to vaccinate the world.

"The United States is providing these half-billion doses with no strings attached," Biden said. "Our vaccine donations don't include pressure for favours, or potential concessions. We're doing this to save lives."

UK Prime Minister Boris Johnson also pledged that the UK would give at least 100 million surplus vaccines to the poorest nations and is expected to urge other G7 leaders to do the same.

Johnson had already called on G7 leaders to commit to vaccinate the entire world by the end of 2022. The group is expected to pledge 1 billion doses during the summit.

About 90% of African countries will miss a September target to vaccinate at least 10% of their populations against COVID-19 as a third wave of the pandemic looms on the continent, a World Health Organisation (WHO) official said on Thursday.

Matshidiso Moeti, WHO regional director for Africa, said the continent required an extra 225 million doses to be able meet the target.

"With vaccine stocks and shipments drying up, the continent's vaccination coverage for the first dose remains stuck at 2% and at about 1% in sub-saharan Africa," Moeti told a weekly news briefing.

"Vaccines have been proven to prevent cases and deaths, so countries that can, must urgently share COVID-19 vaccines. It's do or die on dose sharing for Africa."

Africa Centres for Disease Control director John Nkengasong said separately that 14 African countries were "aggressively" heading towards a third wave of the coronavirus pandemic.

"You can clearly see that the variant that was identified in India is getting a hold on the continent. We continue to analyse the situation and see whether there is correlation between the variant and the third wave," Nkengasong said.
