Astrazeneca Covid-19 Vaccine

British pharmaceuticals giant AstraZeneca said Thursday that its Covid vaccine generated $1.2 billion (1.0 billion euros) in sales in the first half of the year.

Total antibody levels start to wane six weeks after complete immunisation with Pfizer and AstraZeneca vaccines, and can reduce by more than 50 per cent over 10 weeks, according to study published in The Lancet journal.

Drugmaker AstraZeneca said Saturday it was scouring its supply chain to find more doses of its Covid-19 vaccine for Southeast Asia, which is facing its most serious outbreak yet of the virus.

Taiwan's government on Monday said it had granted emergency-use approval to a coronavirus vaccine made locally by Medigen, with experts saying early data suggested it was similarly effective to AstraZeneca's jabs.

AstraZeneca has asked Thailand to extend the timeline for the delivery of 61 million doses of its COVID-19 vaccine by five months, a deputy minister said on Thursday, a move likely to disrupt further the country's sluggish vaccine rollout.

Thailand's immunisation strategy against the coronavirus will see a shot of AstraZeneca's viral vector vaccine administered after one dose of Sinovac's vaccine, its health minister said on Monday.

Growing concern that Covid-19 vaccines being deployed across much of the developing world aren't capable of thwarting the delta variant is prompting some countries to look at offering third doses to bolster immunity.

The GAVI vaccine alliance hopes the Serum Institute of India (SII) will resume exports of the AstraZeneca COVID-19 vaccine from this quarter, it told Reuters, which would be earlier than an "end of this year" forecast by the Indian company.

British Prime Minister Boris Johnson on Friday said he saw no reason why people who received Indian-made AstraZeneca COVID-19 vaccines should be left out of vaccine passport schemes after the European Union did not initially recognise it.

The European Medicine Agency has not received a request for the approval of Covishield in the COVID-19 'vaccination passport' with the European Union, EU said today.

Mixing doses of Covid-19 vaccines from Pfizer Inc. and AstraZeneca Plc creates a strong immune response, according to results from a University of Oxford study, a finding that could enable greater flexibility in the use of scarce supplies.

Delayed second and third doses of the AstraZeneca vaccine boost immunity against COVID-19, a study by Oxford University, which developed the jab with the British-Swedish firm, said on Monday.

AstraZeneca and the University of Oxford on Sunday began new trials to test a modified vaccine against the Beta variant, which first emerged in South Africa.

COVID-19 vaccines made by AstraZeneca and the Pfizer-BioNTech alliance remain broadly effective against Delta and Kappa variants of the COVID-19 causing virus, which were first identified in India, according to a scientific study.

AstraZeneca Plc's COVID-19 vaccine is effective against Delta and Kappa variants, which were first identified in India, the company said on Tuesday, citing a study.
