Allergic reactions and COVID-19 vaccines

Allergic reactions and COVID-19 vaccines 1270 768 Federico de la Roca Pinzón

We are currently immersed in a COVID-19 vaccination campaign (SRAS -CoV-2) and there are many doubts about this regard.

“From ClinicAL we want to convey that vaccination, with the different vaccines approved by the European Medicines Agency (EMA) and the Spanish Medicines and Health Products Agency (AEMPS), is safe.”

Currently, 4 vaccines have been approved for use in Spain, that of the Pfizer, Moderna, AstraZeneca, and Janssen laboratories. Although there is some fear in the population due to the adverse effects reported in recent days, especially with the AstraZeneca vaccine, it is our duty as physicians to remember that the benefit of being vaccinated is greater than the risk of not being vaccinated.

Side effects, although undesirable, are present in every one of the drugs available today. No medication is exempt from producing any adverse symptoms. It is very likely that at some point someone vaccinated will experience symptoms after administration of any of the approved vaccines. But to prevent these effects from being frequent and severe, all laboratories have had to carry out clinical trials with thousands and thousands of patients.

“It is important to remember that no medication in Europe is marketed without proper approval from the EMA. Due to the great responsibility that this entails, this agency is an independent institution and its resolutions are followed by all the member countries of the European Union. Under no circumstances is the latter the ones who issue orders on the EMA.”

In the case of allergic patients, scientific societies have made several recommendations for the administration of the various vaccines against COVID-19 (SARS -CoV-2). In general, all allergic patients can be vaccinated with the 4 vaccines we currently have. The only ones that would be exempt are those with an allergy to some component of the vaccine. The main recommendations are based on the observation period following administration of the vaccine. For those patients with rhinitis, asthma, food or drugs allergies (other than vaccine components) the post-vaccination monitoring time should be 30 minutes. For patients with a history of severe allergic reactions (anaphylaxis) the time under observation should be 45 minutes.

As always, from ClinicAl we remember that our consultations are available to those patients who have doubts about their allergic disease and especially for those who need more information about the vaccination campaign against COVID -19 (SARS -CoV-2) and its likely adverse effects.
