Lower Motor Neuron Facial Palsy Following COVID-19 Infection and COVID-19 AZD1222 Vaxzervria (AstraZeneca) Vaccine Administration: Two Case Reports.

Bell's palsy is a lower motor neuron lesion rarely associated with COVID-19 infection or vaccinations. We documented two cases of Bell's palsy in this report, one after contracting COVID-19 infection and the other after administration of AZD1222 Vaxzervria (AstraZeneca) Vaccine. After excluding all possible causes of Bell's palsy in both cases, we determined that COVID-19 infection and the AZD1222 Vaxzervria (AstraZeneca) vaccine were the causes. Thus, we believe COVID-19 and the AZD1222 Vaxzervria (AstraZeneca) vaccine should be considered as causes of Bell's palsy.
