“…When a non-anaphylactic allergic reaction (urticaria and/or angioedema and/or generalized itching and/or mild respiratory symptoms) occurs after the first dose of a vaccine, the allergic consultation provides for skin allergometry. If the skin tests are positive for PEG, it is also recommended to perform tests with polysorbate 20 and 80 to evaluate the described cross-reactivity, and the possibility of using future COVID-19 vaccines and another vaccine must be considered [ 17 , 18 ]. The polysorbates are also widely used as excipients of liquid and solid formulations of drugs and are capable of inducing both immunologically and non-immunologically mediated anaphylactic reactions [ 19 ].…”

“…Las reacciones alérgicas graves a las vacunas se presentan con más frecuencia con la plataforma de ARN (Pfizer y Moderna). [2][3][4] Según los estudios de fármaco vigilancia efectuados por el CDC (Center for Diseases Control) y la FDA en noviembre de 2020, después de haberse administrado las primeras dosis a 1'893,360 personas se reportaron 175 casos con severas reacciones alérgicas incluyendo anafilaxia. Estas reacciones ocurrieron en minutos a horas después de la vacunación con un promedio de 13 minutos (rango de dos a 150 minutos).…”

“…Ocurrieron 11.1 eventos por millón de dosis, 21 de esos casos correspondieron a anafilaxia. 2,4 El polietilenglicol (PEG) parece ser el blanco de las reacciones, ya que se encuentra como una nanopartícula lipídica que forma la concha del liposoma. Es una molécula que sirve como estabilizador del sistema de la vacuna, sus propiedades higroscópicas tienen capacidad inmunogénica.…”

“…Numerous approved vaccines, specifically those involving the use of PEGylated liposomes within formulation, may result in hypersensitivity reactions (CDC COVID-19 Response Team and Food and Drug Administration, 2021). It is likely that these are the result of complement activation-related pseudoallergy (CARPA) [131] . CARPA is thought to occur through the activation of immune reaction conductors, such as basophils or mast cells, through IgE independent reactions, but is defined by complement activation which can also be observed in COVID-19 patients [132] , [133] .…”
