Rome, March 17 (beraking latest news Salute) – Tomorrow is the day of judgment for the AstraZeneca vaccine, suspended as a precaution in Italy and in some EU countries, the EMA should in fact rule after the investigation launched to clarify the cases of thrombosis in people immunized. The momentary stop had the effect of re-emerging the latent doubts about vaccines and amplifying the fear in those who took the first dose. However, the path of this vaccine has been troubled since its development, with methodological errors in the first part of the experimentation that delayed its arrival, to arrive at the present with the batches seized. Problems that have allowed those who poison the wells of information, with fake news and hoaxes on anti-Covid vaccines, to ride their fears. To clarify the safety of the vaccine for beraking latest news Health is the immunologist Mauro Minelli, responsible for the South of the Italian Foundation for personalized medicine.
“A cause-and-effect relationship between Covid-19 disease and diffuse vascular inflammation (vasculitis) with related thrombo-embolic events is taken for granted, but not between anti-coronavirus vaccines and thrombotic episodes – warns Minelli – also because among the many people that after the AstraZeneca vaccine they underwent precautionary blood tests aimed at evaluating the coagulation structure, there are no noteworthy alterations even among subjects with genetic susceptibility to thrombophilia “.
The most clicked hoaxes are those that temporally link vaccination with some deaths. “We cannot rely exclusively on time data to assert with mathematical certainty that there is a link between the vaccine carried out and any adverse reaction that may have occurred, without having demonstrated a clear causality between the two – explains the immunologist – And to demonstrate convincingly certainty causality it takes some time that the regulatory body rightly took before authorizing its use again after the reported deaths. On the other hand, if, unlike what happened in other countries, Italy had not decided for a precautionary suspension of vaccination, accusations of non-compliance with the adoption of the most correct surveillance measures would have rained down “.
“Another fairly widespread fake news is that, since frequent post-AstraZeneca symptoms would be high fever, headache, widespread pain and then also blood clots capable of producing thrombosis, the vaccine can generate consequences similar to those produced by Sars-Cov- 2 in post-Covid patients because it contains a minimum of virus that is administered with the vaccine “, remarks Minelli.
The AstraZeneca vaccine and all other viral vector vaccines are made from a virus other than the coronavirus. In particular, it is a chimpanzee adenovirus, that is, a virus responsible for colds in monkeys, but rendered unable to reproduce and, therefore, , completely harmless for the recipient – recalls the immunologist – That modified adenovirus, however, is capable of imparting to the immune system of the person undergoing the vaccine the right ‘instructions’ to produce the famous ‘spike’ protein, that which allows Sars-Cov-2 to enter human cells and generate damage. Thus, it happens that the immune system of the vaccinated subject identifies as foreign (not self) the protein produced thanks to the information provided by the transporter adenovirus and, therefore, respond by producing antibodies that will then neutralize the true coronavirus responsible for Covid-19, in the event that this should infect that organism “.
“It is important to underline that the adenovirus of which this vaccine is composed cannot replicate and, therefore, does not cause disease or transport it, simply for the fact that it is an adenovirus and inactivated, consequently it is not able to cause not even a sneeze “, concludes Minelli.
