A senior European Medicines Agency official said it might be worth abandoning AstraZeneca’s coronavirus vaccine for all age groups where alternatives are available, in an interview published Sunday.
Marco Cavaleri, head of vaccine strategy at the EMA, also told the Italian newspaper La Stampa that the Johnson & Johnson jab should be used preferentially for those over 60 years of age.
Both vaccines called viral vector are authorized for all over 18 years of age, but have been reported in rare blood clots. The EU has also authorized two mRNA vaccines, Pfizer / BioNTech and Moderna.
On Saturday, Italy restricted vaccines against AstraZeneca to people aged 60 and over after concerns about increased health risks younger people.
Asked whether it would not be better to ban AstraZeneca even for those over 60, Cavaleri said: “Yes, and it is an option that many countries, such as France and Germany, are considering in view of the increase in the availability of mRNA vaccines.
“However, the incidents were very rare and after the first dose. It is true that there is less data on the second dose, but in the UK (the vaccination program) is going well.”
He added: “Enter young people the risks of disease are diminishing and the message for them could be to use mRNA vaccines instead, but the decision is in the hands of individual states. “
He noted that the single-shot Johnson & Johnson vaccine has “fewer problems than AstraZeneca,” noting that less had been used.
“With a dose it is useful for some hard-to-reach categories, but it is still an adenovirus (vaccine) and it is preferable to reserve it for those over 60,” he said.
In a brief statement on Twitter later, the EMA said: “Misinformation is going around today.
“This is the situation: AstraZeneca benefit / risk balance # COVID19 vaccine it is positive and continues to be authorized for all populations “.
Messaging RNA genetic technology trains the body to reproduce cutting-edge proteins, similar to those found in coronavirus. When exposed to the actual virus later, the body recognizes the proteins in the ear and is able to fight them.
Viral vector vaccines such as AstraZeneca and Johnson & Johnson use the genetic version of a common cold that causes adenovirus as a “vector” to transmit genetic instructions to human cells.
