Acute facial paresis as a possible complication of vaccination against SARS-CoV-2

Abstract

Although acute facial nerve palsy (Bell's palsy) is explicitly mentioned in the information sheets for vaccines as a possible complication of vaccination against SARS-CoV-2, from our point of view the benefits of the vaccination clearly outweigh the possible risks. At most, if at all, a slightly increased risk can be derived from the previous case reports. In general, the risk of acute facial palsy is described in association with many vaccinations. The risk, if any, does not appear to be a specific risk of SARS-CoV-2 vaccines. On the other hand, cases of acute facial palsy as symptom of a COVID-19 disease have also been described, so that the theoretical question arises as to the extent to which the vaccination may prevent rather than promote the occurrence of facial palsy. Ultimately, if acted quickly, acute facial paralysis can be treated well and its severity and sequelae cannot be compared with the severity of a COVID-19 disease and its possible long-COVID sequelae.
