In the UK, people with significant allergic reactions will not receive the Covid vaccine. The decision was made directly by the national drug control authority, Mhra, after two people, vaccinated on the first day, experienced allergic reactions following the administration of the Pfizer / Biontech vaccine. After the communication, doubts have grown in those who have had to deal with some type of allergy in the past.
As reported by Il Messaggero, in addition to this problem, there was also the theft of some documents related to the vaccine that is being used. the cyber attack it was made against the EMA, the European drug agency. The pharmaceutical company was interested in pointing out that “Neither the BioNtech nor Pfizer systems were hacked in connection with this incident and we are not aware of the personal data that would have been breached.”.
Reactions to the vaccine
As to allergic reactions what can occur after the administration of the vaccine, the discussion is broader. In fact, 10-15% of Europeans suffer from allergies, be it asthma, rhinitis, atopic dermatitis or even food allergies. Regardless of age. However, our country still has to wait for authorization from the EMA before starting the vaccination plan. However, according to scientists, the vaccine to combat the coronavirus can also be administered to people with allergies, as long as their health status is communicated to the health worker who will have to do the prophylaxis.
Paola Migliorini, director of the specialization school in Allergology and Clinical Immunology at the University of Pisa, explained that “As for all vaccines, the risk is represented by immediate reactions, that is, a few minutes or an hour after administration; to have variable severity from local reactions to systemic reactions such as anaphylaxis. Late reactions are also possible, after 24 to 48 hours, mostly not serious. “. Immediate allergic reactions can cause hypotension and severe breathing difficulties, up to loss of consciousness. More people who have had allergic reactions to vaccines, foods, or medications in the past are at higher risk. As well as those who have a prescription for self-injecting adrenaline, the first-line treatment of severe anaphylaxis, so to speak, anaphylactic shock.
It must be said that allergic reactions to vaccines are quite rare, especially serious, and that they usually occur in less than 1 in 100,000 people. Francesca Larese Filon, an allergist at the University of Trieste, specified that “All vaccines can cause allergic reactions, it depends on the excipients, the substances that make them up, how they were produced. So it is not surprising that two people in Britain have had allergic reactions. It is about understanding how frequent these reactions are and towards what type of product these reactions are formed. These are generally rare events. In any case, vaccinations should be carried out in a medical setting, where patients wait 15 to 20 minutes, and thus the possible appearance of allergic reactions can be assessed. “. The two 40-year-olds who have had allergic reactions in Great Britain are in no case in serious condition and are already in the process of recovery.
These are not common allergies.
Enrico Maggi, former president of the Italian Society of Allergy, Asthma and Clinical Immunology and honorary professor of internal medicine at the University of Florence, explained that we are not talking about common allergies, such as those from mites or environmental substances, but in more ways rare. such as those caused by food, drugs. “In this case it is a question of a minimal sensitization towards minor allergens. It is good to remember that any vaccine can cause these types of problems that can still be solved “.
However, the important thing is not to underestimate the clinical picture of each subject and it will be the treating physician or the allergist who decides what to do. “The difficulty could be in making an accurate history of the sensitization that the patient may have. So in that case it is better to do a premedication. Any doctor, in fact, can implement countermeasures that are used to solve the problem of allergic reactions. “ Maggi concluded.
