The temporary suspension of the Astrazeneca vaccine also in Italy is confusing and worrying. The hypothetical serious adverse effects related to anticovidic inoculation are raising serious doubts, especially among those who have already received the first dose. Until new data is available, the question remains open. Antonio Cassone, former director of Infectious Diseases at the Istituto Superiore di Sanità reassures: «Whoever has received the Astrazeneca vaccine and is well, should not do anything, just wait for the second dose to be available. Remember that the common negative effects are similar to those of many other vaccines. Of course, it cannot be ruled out that when it comes to millions of people, some subjects may have particularly serious effects, such as thrombosis or thromboembolism ”.
Astrazeneca, the vaccine plan slows down: doses are suspended, tens of thousands of reservations are canceled
SIDE EFFECTS
At the moment, the correlation has not been verified. “The causal link and the alleged side effects have not been confirmed – observes Roberto Luzzati, Professor of Infectious Diseases at the University of Trieste – there is a temporal coincidence in some cases, in others less. The evidence to date leads us to say that those who have received the vaccine should not be subjected to further investigation. Also because “the incidence of thrombotic or thromboembolic events in general is much higher than what could have occurred after the vaccine.” The large number of people who have already received the first dose without particular symptoms should be reassuring.
“We must be calm and be aware that millions of people have been vaccinated and the reported cases of reactions, whose link with vaccination has not yet been proven, are a few dozen”, explains Massimo Andreoni, director of Infectious Diseases at the Tor Polyclinic Vergata. in Rome. and scientific director of Simit (Italian Society for Infectious and Tropical Diseases) – The alterations that occurred then seemed close to the dose. To be sure, it is good to be attentive if particular and relevant elements arise, such as great dyspnea, or chest pain. In that case it is better to call your GP.
In any case, recalls Roberto Giacomelli, director of clinical immunology and rheumatology at the Campus Bio-medico university hospital in Rome, “if side effects appear, we know how to treat them. Generally, they appear around a series that fluctuates between 1-2 percent, they are mild and therefore do not need to be alarmed. We remind them that unfortunately there is a cultural prejudice towards prophylaxis: in the last 20 years we have been vaccinated against smallpox or polio with a viral vector vaccine and nobody wondered about all these problems ”.
However, there are even those who believe that taking a pill before inoculation can help. “We must be serious: it is more dangerous to take an NSAID and contract hemorrhagic gastritis – warns Giacomelli – than to prevent a possible headache from a vaccine”.
RISK EXAGERATIONS
But there are those who go even further. “Someone suggests to the subjects who are going to be vaccinated that they even make heparin – warns Francesco Menichetti, professor of Infectious Diseases at the University of Pisa – but in doing so they will have large muscle bruises, because it is an anticoagulant. We do not have to do any prophylaxis before vaccination, we must have tachipyrine or an anti-inflammatory at our disposal in case the classic ailments arise after the dose, that is, fever or muscle aches. And then the allergic phenomena come close to the inoculation of the vaccine and are treated immediately. We take into account that the preventive suspension of the vaccine does not mean the recognition of a cause-effect relationship.
Maybe there is a way to try to understand if something goes wrong after the administration. “If someone scrupulously wants to check for coagulation problems – suggests Francesco Romeo, president of the College of Full Professors of Cardiology – they can check the value of the d-dimer. If disturbed, heparin can be used. This test can be performed, for example, by cardiac patients with deep vein thrombosis or thromboembolic problems. But let us remember that so far we do not have data to think that the anticovide vaccine can determine an activation of coagulation ».
