Facial palsy not associated with the Pfizer vaccine

A case-control study from Israel where the majority of the population has been vaccinated with the Pfizer vaccine found the following: Over the two month study period, 37 patients were admitted for facial nerve palsy, 22 (59.5%) of whom were male, mean age of 50.9  years. Among 74 matched controls (2:1 ratio) with identical age, sex, and admittance date, a similar proportion was vaccinated recently (44 [59.5%]). The adjusted odds ratio for exposure was 0.84 (95% CI, 0.37-1.90; P = .67), which means there was a non-significant lower risk of facial palsy in those who had been vaccinated with the Pfizer vaccine.

Furthermore, analysis of the number of admissions for facial nerve palsy during the same period in preceding years (2015-2020) revealed a relatively stable trend (mean [SD], 26.8 [5.8]; median, 27.5 [range, 17-35]).
