Here's the latest on the pandemic from around the world.
Vietnam reported 102 new COVID-19 infections on Sunday as the Southeast Asian country battled a fast-spreading outbreak which Prime Minister Pham Minh Chinh said threatened political stability if not brought under control.
The new cases raised the total to 3332 since the pandemic began, with 35 deaths, the Ministry of Health said.
Vietnam has been praised for its record in containing its outbreaks quickly through targeted mass testing and a strict, centralised quarantine programme.
China will set up "a line of separation" at the summit of Mount Everest to prevent the mingling of climbers from COVID-hit Nepal and those ascending from the Tibetan side as a precautionary measure, Chinese state media reported on Sunday.
Everest base camp on the Nepalese side has been hit by coronavirus cases since late April. The Nepalese government, starved of tourism revenue, has yet to cancel the spring climbing season, usually from April to early June before the monsoon rains.
China carried out about 9.36 million vaccinations against COVID-19 on Saturday, bringing the total number administered to 317.59 million, according to data released by the National Health Commission.
Emirates airline said on Sunday it will fly medical supplies from Dubai to nine cities in India free of charge from this week to help battle a devastating upsurge in the coronavirus.
International aid has poured in for India, where record infection rates have overwhelmed hospitals, depleting medicines, oxygen tanks and other supplies.
The United States is closer to getting the coronavirus pandemic under control and health officials are focused on the next challenge: getting more Americans vaccinated, the White House COVID-19 response coordinator Jeff Zients said on Sunday.
A total of 1770 new cases of COVID-19 were recorded in the United Kingdom on Sunday, with the seven-day total of 14,659 cases down by 4.3 percent compared with the previous seven days.
The country recorded two new deaths within 28 days of a positive COVID-19 test. The seven-day death toll of 67 was down by 39.1 percent compared with the previous seven days.
The data showed that 35.37 million people, or 67.2 percent of the UK adult population, have now received a first dose of COVID-19 vaccine. Of those, 17.67 million, or 33.5 percent of adults, have received the recommended two doses.
The number of COVID-19 patients in French intensive care units fell below 5000 for the first time since late March on Sunday, health ministry data showed.
The number was down for a sixth day in a row at 4971, against 5005 the previous day, the ministry said.
The European Union has not yet made any new orders for AstraZeneca vaccines beyond June when their contract ends, European Internal Market Commissioner Thierry Breton said on Sunday.
Breton also said he expected that the costs of the EU's recent order for more doses of Pfizer-BioNTech vaccines would be higher than the earlier versions.
Africa and the Middle East
South Africa's health ministry said on Saturday it had detected the first four cases of a new coronavirus variant that emerged in India and was responsible for a surge of infections and deaths in the Asian country.
