COVID-19: What you need to know about the coronavirus pandemic on 15 October

Confirmed cases of COVID-19 have passed 239.6 million globally, according to Johns Hopkins University. The number of confirmed deaths stands at more than 4.88 million. More than 6.6 billion vaccination doses have been administered globally, according to Our World in Data.

Sydney will allow in fully vaccinated travellers from overseas from 1 November - without needing to quarantine. The rule change would initially only benefit citizens.

France has donated more than half a million doses of the AstraZeneca COVID-19 vaccine to Nigeria through the COVAX vaccine-sharing facility.

The EU's drug regulator has started a real-time review of AstraZeneca's antibody-based COVID-19 therapy.

Latvia has cancelled most planned hospital operations from Monday to free up beds and staff as COVID-19 cases increase.

UK Health Minister Sajid Javid said yesterday that the COVID-19 situation is 'quite stable at this point'. 42,776 new COVID-19 cases were reported on Wednesday - the highest figure since mid-July.

US President Joe Biden told the visiting Kenyan President Uhuru Kenyatta yesterday that the United States is set to make a one-time donation of more than 17 million doses of the Johnson & Johnson COVID-19 vaccine to the African Union.

Biden said the 17 million doses will be in addition to 50 million the United States has already donated to the African Union.

The African Union, which has 55 member states and a combined population of over 1.3 billion people, has accused vaccine manufacturers of not giving its members fair access. Of 5.7 billion doses of coronavirus vaccines administered around the world by mid-September, only 2% had been in Africa.

The 17 million doses of J&J are available immediately and will be delivered to the African Union in the coming weeks, the White House said.

The tiny Pacific Island nation of Palau has the world's highest vaccination rate, the Red Cross said yesterday.

99% of the country's population over 12 has had both shots of a vaccine against COVID-19, the International Federation of Red Cross (IFRC) said, citing government figures which also show that this amounts to 16,152 people.

That puts Palau, an archipelago of 500 islands in the western Pacific Ocean, in the "top spot", the IFRC said in a statement. Other nations in the region continue to lag behind though. Less than 10% of the Solomon Islands (population 650,000) and Kiribati (population 119,000) are vaccinated, the IFRC said.
