AstraZeneca Covid-19 vaccine booster shot effective against Omicron: Oxford lab study
A three-dose course of AstraZeneca's Covid-19 vaccine is effective against the Omicron coronavirus variant, the pharmaceutical company said on Thursday, citing data from an Oxford University lab study.
The study, yet to be published in a peer-reviewed medical journal, showed 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.
After a three-dose course of the vaccine, neutralising levels against Omicron were similar to those against the virus's Delta variant after two doses, the company added.
The Anglo-Swedish drugmaker said researchers at Oxford University who carried out the study were independent from those who worked on the vaccine, Vaxzevria, with AstraZeneca.
To reinforce its Indo-Pacific strategy, and in what is being seen as a response to China's aggressive outreach to Pacific Island states, the United States (US) - along with Australia, New Zealand, United Kingdom and Japan - announced a new Partners in Blue Pacific initiative on Friday.

Russia's army has “fully occupied” the key Ukrainian city of Severodonetsk after weeks of fighting, its mayor said on Saturday, an important strategic win for Moscow as it seeks to gain full control over the east of the country.

President Joe Biden criticised the US Supreme Court for making “terrible decisions”, a day after it struck down the constitutional right to abortion. Biden commented during a signing ceremony on Saturday for gun safety bill he supports, though he continued to sidestep questions about reforms to the court sought by some Democrats.

Ukraine's Severodonetsk was "fully occupied" by the Russian army, its mayor said on Saturday, after weeks of fighting over the key eastern city. The Ukrainian army on Friday said it would withdraw its forces from the city of some 100,000 inhabitants before the war to better defend the neighbouring city of Lysychansk. Mayor Oleksandr Striuk said civilians had started to evacuate the Azot chemical plant, where several hundred people had been hiding from Russian shelling.
Ukraine said it came under "massive bombardment" Saturday from neighbouring Belarus, a Russian ally not officially involved in the conflict, the day after announcing a retreat from the strategic city of Severodonetsk. Belarus has provided logistic support to Moscow since the February 24 invasion, particularly in the first few weeks, and like Russia has been targeted by Western sanctions -- but is officially not involved in the conflict.
