More than half of Australia's adult population are now fully vaccincated against COVID-19, in a milestone towards the easing of restrictions.

The European Medicines Agency hopes to decide in early October whether to endorse a third booster dose of the Pfizer/BioNTech COVID-19 vaccine.

Viet Nam has pushed backed the reopening of the resort island of Phu Quoc to foreign visitors until November. It comes as insufficient vaccine supplies mean they failed to hit targets to vaccinating locals.

South Korea has recorded its highest ever number of confirmed daily COVID-19 cases - 2,434.

Singapore has also reported its highest daily COVID-19 case rise since the start of the pandemic - 1,504.

Novavax and its partner, the Serum Institute of India, have applied to the World Health Organization for emergency use listing of Novavax's COVID-19 vaccine.

Yemen has received its third batch of COVID-19 vaccines through the COVAX global vaccine-sharing scheme.

A World Health Organization panel has recommended the use of Regeneron and Roche's COVID-19 antibody cocktail for patients at high risk of hospitalization and those severely ill with no natural antibodies.

The treatment has already been granted US emergency use authorization. It's currently under review in Europe, while Britain approved it last month.

While acknowledging costs associated with the treatment, the WHO panel said that given the recorded benefits of the therapy, "the recommendations should provide a stimulus to engage all possible mechanisms to improve global access to the intervention and associated testing".

In a separate statement, the WHO called on Regeneron to lower prices and distribute the treatment equitably worldwide, especially in low- and middle-income countries. The agency also urged the firms to transfer tech to help make biosimilars.

Sweden is considering giving a third booster dose of COVID-19 vaccines to more of its population over concerns about waning protection from two shots.

Sweden has vaccinated 83% of the population aged over 16 with one dose and 76% with two doses. The country's public health agency recently identified some 40,000 people in need of a third dose, but said on Thursday more could soon be eligible.

"There are signals from abroad that indicate the protection from the vaccination is fading after some time, especially in those who are older," Public Health Agency official Sara Byfors told a news conference. "It is important to meet that with a third dose."
