A three-dose course of AstraZeneca's COVID-19 vaccine is effective against the rapidly-spreading Omicron coronavirus variant, the pharmaceutical company said on Thursday, citing data from an Oxford University lab.

Findings from the study, yet to be published in a peer-reviewed medical journal, match those from rivals Pfizer-BioNTech and Moderna which have also found a third dose of their shots works against Omicron, Reuters reported.

The study on AstraZeneca's vaccine, Vaxzevria, showed that after a three-dose course of the vaccine, neutralizing levels against Omicron were broadly similar to those against the virus's Delta variant after two doses.

The London-listed company said researchers at Oxford University who carried out the study were independent from those who worked on the vaccine with AstraZeneca.

"As we better understand Omicron, we believe we will find that T-cell response provides durable protection against severe disease and hospitalizations," Mene Pangalos, the head of AstraZeneca's biopharmaceuticals R&D said, referring to a critical component of the immune system that respond to fight infection.

Antibody levels against Omicron after the booster shot were higher than antibodies in people who had been infected with and recovered naturally from COVID-19, the Anglo-Swedish drugmaker added.

Although the early data is positive for the company, AstraZeneca said on Tuesday it was working with its partner Oxford University to produce a vaccine tailored for Omicron, joining similar efforts from other vaccine-makers.

The Oxford study analyzed blood samples from those infected with COVID-19, those vaccinated with two doses and a booster, and those previously infected with other variants of concern. It included samples from 41 people given three doses of Vaxzevria.

Scientists and governments are scrambling to bolster defenses against Omicron with shots and therapies, as the variant threatens to become dominant globally and has prompted renewed curbs ahead of the holidays to contain infections.

Britain earlier this month backed the use of boosters after it found that a third dose significantly restored protection against mild disease caused by Omicron, in part reversing an otherwise steep drop in vaccine effectiveness.

Belgium's King Philippe described abuses in Gaza as a "disgrace to humanity" in a speech on the eve of Monday's national day, unusually direct remarks on international affairs from a monarch who traditionally avoids public politics.

"I add my voice to all those who denounce the serious humanitarian abuses in Gaza, where innocent people are dying of hunger and being killed by bombs while trapped in their enclaves," he said speaking at his palace in Brussels, Reuters reported.

"The current situation has gone on for far too long. It is a disgrace to all of humanity. We support the call by the United Nations Secretary-General to immediately end this unbearable crisis."

It was the first time Philippe has spoken out so strongly and unambiguously about a conflict in public. Belgium's federal government has been more reserved in its criticism of the conflict in Gaza.

The king's role in Belgium is limited to giving advice, support, and warnings to the government without making any political decisions.

Israel launched its assault on Gaza following an October 2023 attack on Israeli towns by Hamas-led fighters. Since then, Israeli forces have killed more than 59,000 people in Gaza, according to health officials there. Much of the territory has been laid to waste and Israel has restricted food and other supplies.

Israel denies that its forces commit abuses in Gaza and says restrictions on supplies are needed to prevent aid from being diverted by militants.
