ROME – Italy’s medicines agency yesterday approved the AstraZeneca coronavirus vaccine for adults, but recommended that alternatives be given to people over 55.
Aifa’s decision comes a day after the European Union gave the green light to the jab, but Germany’s vaccine commission recommended against using it on older people amid questions over its effectiveness that have been rejected by the company.
“Aifa authorises the AstraZeneca vaccine for the prevention of Covid-19 in individuals over the age of 18, as per European Medicines Agency guidance.”
But, it noted “a level of uncertainty” about claims on the jab’s effectiveness in people over 55, because the age group was “poorly represented” in trials.
To help with the best use of the vaccine, it recommended “preferential use of the AstraZeneca vaccine, pending further data, in subjects between 18 and 55 years old, for whom more solid evidence is available”.
It urged the “preferential use of messenger RNA vaccines in older and/or more frail subjects”.
So-called mRNA vaccines include the Pfizer-BioNTech and Moderna jabs, and are based on a new technology previously untested in a real-world situation.
They use an inert snippet of genetic code from Covid-19 to trigger an immune response in the body that can repel the active virus.
Many other vaccines – including that produced by Oxford University and AstraZeneca – are variants of the method used for flu jabs, based on a virus that has been killed and rendered harmless.
AstraZeneca earlier rejected German media questioning the vaccine’s effectiveness in over-65s.
“Reports that the AstraZeneca-Oxford vaccine efficacy is as low as 8% in adults over 65 years are completely incorrect,” said the firm in a statement on Monday.
“In November, we published data in The Lancet demonstrating that older adults showed strong immune responses to the vaccine, with 100% of older adults generating spike-specific antibodies after the second dose.” – AFP, January 31, 2021
