“Today, a vaccine that was useful to us in times of emergency is retiring” Covid. This was underlined by Giacomo Gorini, the Italian researcher who at the University of Oxford, in the hardest days of the pandemic, worked on the anti-Covid vaccine then produced and distributed by AstraZeneca. The expert underlines this via social media, in a post on informed the company – there was no longer any demand for the Vaxzevria* vaccine and consequently it was no longer produced or distributed. Therefore, not foreseeing a future application”, it was decided to “withdraw the marketing authorization” Aic.
The withdrawal of the vaccine
The withdrawal of the AIC in the EU came into force on 7 May. And from the European Medicines Agency Ema Marco Cavaleri, who is responsible for health risks and vaccination strategies and chairs the Emergency Task Force (ETF), heard from Adnkronos Salute in recent days and had clarified that “this is in line with the expectations that vaccines no longer used and updated are withdrawn, as per our indications. We are working with all manufacturers to reduce the number of approved vaccines, so as to manage only those that are regularly updated as per our recommendations”.
Side effects
Gorini intervened in the debate that arose after the spotlight was turned back on the AstraZeneca vaccine which, as he himself recalled, “admitted for the first time in court that the vaccine can cause these rare and serious side effects”. But, the expert points out, it is a first time only for the courtroom. Because he actually “has been talking about it freely for years”. Now, Gorini continues via social media, “it is right that we continue with mRna, a very safe and effective technology”. But the AstraZeneca vaccine, we read in his posts, “according to some estimates it saved 6 million lives in the first year of use alone, more than any other vaccine in the same period. Like any other drug, it has side effects, some serious. Serious ones are very rare in frequency and comparable to those of any other drug. Otherwise it wouldn’t have been used.”
“Those famous thromboses associated with thrombocytopenia caused a sensation, given the historical period and the particular attention of the media.” Well, recalls Gorini, “these are similar, by nature, to those caused by another approved drug, heparin. I’m not surprised that it’s being talked about again, but this is non-news, given that the presence of these side effects, as with any other drug, has been known for years.and both the company and regulators have always spoken openly about it.”
Not only that, he adds: “The fact that these very rare side effects are known is actually a sign that the famous ‘system’ works: the regulatory bodies have noticed it in pharmacovigilance, the company and the scientific community have taken note of it without problems. Given that mRNA vaccines are truly exceptional in terms of safety (never having potentially lethal side effects), it made sense to increase the availability of doses and once viral circulation was reduced, to focus only on those.”
The AstraZeneca vaccine, the scientist points out, “represented a first aid tool during the initial phases of the pandemic, given its excellent safety profiles and its effectiveness particularly against serious disease. It saved many, many, many lives” . Gorini finally concludes with a reflection that reveals a bit of bitterness: “Those who hate my category – he writes – generally portray scientists as mass manipulators, cover-ups of side effects. The rare side effects of the AZ vaccine were reported precisely by scientists.”
