EU regulator authorises AstraZeneca vaccine for all adults

Regulators have authorised AstraZeneca’s coronavirus vaccine for use in adults throughout the European Union.

The European Medicines Agency (EMA) licensed the vaccine to be used in people 18 and over, though concerns had been raised this week that not enough data exist to prove it works in older people.

The shot is the third Covid-19 vaccine given the green light by the European Medicines Agency, after ones made by Pfizer and Moderna. Both were authorised for all adults.

The EMA’s decision requires final approval from the European Commission, a process that occurred swiftly with the other vaccines.

With trials showing about 60% efficacy, the vaccine appears to offer less protection than ones already authorised, but experts have said any vaccine with an efficacy rate of over 50% could help stop outbreaks.

The agency recommended the vaccine’s use in older people, despite limited data regarding its efficacy in people over 55, citing the immune responses seen and experience with other vaccines.

“At least some protection is expected,” Bruno Sepodes, of the EMA’s expert committee, said on Friday at a news briefing. He acknowledged that “the exact level of protection cannot be estimated for the time being”.

Many countries on the continent have been struggling to vaccinate people as quickly as Britain, Israel, the US and elsewhere, and it was long hoped that the AstraZeneca shot would help speed things up at a time when countries face surging cases in a pandemic that has taken the lives of more than 400,000 people in the 27-nation bloc.

The EU bet heavily on the shot, which is cheaper and easier to handle than some other vaccines, with orders for 300 million doses to be delivered after authorisation and options for another 100 million doses.

“None of them is a magic wand on its own, but together they provide tools and options to prevent different aspects of the disease,” said Emer Cooke, the head of the EMA.

The AstraZeneca vaccine has been authorised for use in all adults in other countries, even though only 12% of the participants in its research were over 55 and they were enrolled later, so there has not been enough time to get results.

EMA’s decision authorises AstraZeneca’s vaccine to be used across the bloc, but individual countries can still decide how and to whom they will give the doses they receive.

Germany has indicated it could follow a similar path.

The country’s independent vaccine advisory committee recommended on Friday that the shot only be given to people under 65.

The committee, known by its German acronym STIKO, said that “there currently isn’t sufficient data to assess the vaccine effectiveness from the age of 65”.

The final decision rests with the government, but they are likely to follow this advice.

Thomas Mertens, the head of the German advisory committee, said the general approval by EMA was “confusing” in light of the data but that he and his colleagues would gladly update their recommendation if further data comes in. “It’s not set in stone,” he said.

The EMA’s executive director declined to say whether the regulator saw a problem with such an approach.

The agency assessed four trials in the UK, Brazil and South Africa and said the research showed the vaccine proved to be about 60% effective by reducing the number of people who got sick.

The trials have not yet shown whether the vaccine can stop disease transmission.

A separate study testing the AstraZeneca vaccine in the US is still under way.

Professor Andrew Pollard, director of the Oxford Vaccine Group that developed the shot together with AstraZeneca, welcomed the decision.

“The recommendation by the European Medicines Agency is an important milestone in extending access to the Oxford/ AstraZeneca vaccine in our region and providing further endorsement that, after the rigorous scrutiny of regulators, the vaccine can be used to help protect populations from the coronavirus pandemic,” he said in a statement.

Exacerbating concerns about supplies to the bloc, which is home to some 450 million people, Moderna told countries including Italy and Denmark the company would be delivering fewer vaccines than originally expected.

Jens Spahn, the German health minister, said on Friday he understood many were waiting impatiently for the vaccine, but cautioned that “several hard weeks of vaccine shortage still lie before us”.

Two more vaccine makers also recently announced results, with Novavax saying this week that its shot appears 89% effective based on early findings and Johnson & Johnson saying its long-awaited single-shot vaccine was 66% effective at preventing moderate to severe illness.

Also on Friday, the European Commission introduced measures to tighten rules on the exports of shots produced in the 27 EU countries.

The “vaccine export transparency mechanism″ will be used until the end of March to control vaccine shipments to non-EU countries and to ensure that any exporting company based in the EU first submits its plans to national authorities.

The EU insisted the measure is not an export ban.

Officials said the mechanism would not affect humanitarian deliveries and shipments to countries covered by the COVAX initiative co-led by the World Health Organisation.

The European Union and AstraZeneca also agreed on Friday to make public a heavily redacted version of their coronavirus vaccine agreement.
