evidence: Coronavirus Disease 2019 Vaccines Coronavirus disease 2019 (COVID-19) vaccines can be administered concomitantly with any other vaccines. See COVID-19 vaccine and immunization information, including interim clinical considerations. [...] Vaccine components can cause allergic reactions in some recipients. Reactions can be local or systemic and can include anaphylaxis or anaphylactic-like responses. A previous severe allergic reaction to any vaccine, regardless of the component suspected of being responsible for the reaction, is a contraindication to future receipt of the vaccine. Vaccine components responsible for reactions can include adjuvants, animal proteins, antibiotics, the vaccine antigen, preservatives (e.g., thimerosal), stabilizers (e.g., gelatin), or yeast.
