Las covid vaccines They have been a key tool in the fight against the pandemic, and are essential to significantly reduce the risks associated with infection by the virus. However, like all medicines they can cause some side effects on rare occasions, which in this case are of minimal severity.
Thus, the 19th pharmacovigilance report of the Spanish Agency for Medicines and Health Products (AEMPS) found that these serums can in some cases cause two side effects that had not been documented up to now: dizziness and cutaneous vasculitis.
minimal risk
Specifically, cutaneous vasculitis is considered a possible side effect of vaccination with Astrazeneca (Vaxzevria). It consists of a inflammation of the blood vessels in the skinwhich in turn causes the appearance of a skin rash and small red or purplish spots or bruises.
In principle, cutaneous vasculitis does not carry any risk of major complication, and tends to be self-limiting (disappear by itself). Vasculitis is only a significant problem when it affects larger and deeper blood vessels (in which case it is not categorized as cutaneous).
Thus, the dizziness and this effect add up to a long list of side effects that, with different frequency, have been registered in the case of the different sera (presenting slight variations between them). The most common are fever, malaise, headache, myalgia (generalized pain) and arthralgia (joint pain).
Be that as it may, it is important to highlight something that the health authorities at various levels have not stopped repeating since the beginning of the vaccination campaigns: the vaccines are approved based on strict procedures and protocols that ensure that they are supported by scientific evidence. In all cases where vaccination is indicated, the benefits of receiving the serum outweigh the potential risks.
