AstraZeneca Vaccine Only Recommended For People Under 65, German Health Officials Say


Germany’s vaccine commission has recommended that the coronavirus vaccine developed by AstraZeneca and the University of Oxford should not be given to people older than 65 years, the German Interior Ministry said Thursday.

The Standing Committee on Vaccination (STIKO) at Germany’s Robert Koch Institute (RKI), the country’s main public health authority, has found there is insufficient data on the effectiveness of the vaccine for this age group, according to a statement from the ministry.

“Due to the small number of study participants in the age group ≥65 years, no conclusion can be made regarding efficacy and safety in the elderly. This vaccine is therefore currently recommended by STIKO only for persons aged 18-64 years,” the panel said in its recommendation.

The United Kingdom, whose regulator approved the Oxford/AstraZeneca vaccine nearly a month ago, has been administering doses to people older than 65.

In its report, the regulator, the MHRA, said there was “limited information available on efficacy in participants aged 65 or over, although there is nothing to suggest lack of protection.”

The EU has ordered 300 million doses of the AstraZeneca vaccine — which could be approved for use by the European Medicines Agency (EMA) as soon as Friday — with an option to purchase an additional 100 million doses.

An AstraZeneca spokesperson said it awaited a regulatory decision by the EMA soon. “Reports that the AstraZeneca/Oxford vaccine efficacy is low in adults over 65 years is not an accurate reflection of the totality of the data,” the spokesperson said.

“The latest analyses support efficacy in this age group, which we expect to be published by the EMA in the coming days. The most recent Lancet publication has demonstrated that older adults showed strong immune responses to the vaccine, with 100% of older adults generating spike-specific antibodies after the second dose.”

AstraZeneca’s chief executive, Pascal Soriot, said in an interview with Italy’s la Repubblica newspaper Tuesday that “the issue with the elderly data is not so much whether it works or not. It’s that we have today a limited amount of data in the older population.”

Soriot said this was because the Oxford scientists running the vaccine trials did not want to recruit older people until they had “accumulated a lot of safety data” for those aged 18 to 55.

“Essentially, because Oxford started vaccinating older people later, we don’t have a huge number of older people who have been vaccinated. So that’s what the debate is,” he said. “But we have strong data showing very strong antibody production against the virus in the elderly, similar to what we see in younger people. It’s possible that some countries, out of caution, will use our vaccine for the younger group.”

Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene and Tropical Medicine, stressed that the German decision was “not a regulatory decision, but draft advice on usage” in comments to the UK’s Science Media Centre.

It was “well known that the clinical data for this vaccine were limited for those aged 70 and over,” he said, because AstraZeneca recruited older age groups later than younger age groups, allowing less time for cases to accrue.

“There is no reason at all for anyone in the UK or elsewhere to think that this Oxford/AstraZeneca vaccine is ineffective at any age,” Evans said. “Its ability to be delivered to people in GP surgeries and care homes makes it a vital component in the attempts to reduce hospitalization and deaths, especially in the elderly.”

Jim Naismith, director of the Rosalind Franklin Institute and professor of structural biology at the University of Oxford, also sought to allay concerns, noting that German scientists had concluded that the vaccine was safe and effective for under-65s.

“Their assessment is that effectiveness is not yet demonstrated for over 65s. They have not said the vaccine is ineffective for over 65s,” he told the Science Media Centre.

“Good faith discussions about what evidence is needed for vaccine effectiveness are really important. Experimental evidence and reasoned debate, not over heated rhetoric, will resolve this issue.”
