ABSTRACT
The SARS-CoV-2 virus pandemic was presented as a disease with great morbidity and mortality. Since then, the race for the production of a vaccine that would prevent serious disease and reduce transmission began. Numerous laboratories joined the effort and multiple platforms were developed: mRNA, viral vector, viral protein subunits, DNA, live attenuated viruses, etcetera. Only the first two have been applied in vaccination campaigns. However, none is exempt from causing side effects, which can be immediate and/or late. These effects are explained by the direct release of histamine and vasoactive peptides mediated by IgE or activation of the alternative complement pathway. Late lesions are related to the deposition of immune complexes, vascular damage and infiltration by inflammatory cells in the skin, at the site of the vaccine application or remotely, causing subacute dermatitis or purpuric plaques. So far, over 50 years of age have been vaccinated in Mexico, a population that is under multiple treatments and in whom toxic intermediate metabolites, the viral effect or the mechanism of action of the drugs themselves can act together to develop complex clinical picturesREFERENCES
