Dear Editor,


We would like to comment on the article “Risk and characteristics of Bell’s palsy in adults as an adverse event following COVID-19 vaccination: a retrospective study [1].” Kim et al. looked at the likelihood and clinical features of BP following COVID-19 vaccination [1]. Patients with vaccine-related BP had a higher chance of good and quicker recovery of facial nerve function than those with vaccine-unrelated BP, according to Kim et al. research’s [1]. According to Kim et al., COVID-19 vaccinations, particularly mRNA-based vaccines, may be linked to cases of BP that have different clinical characteristics, are more common in young people, commonly accompanied by taste alterations, and have a quick and complete recovery [1].

The actual relationship may or may not differ from that presented in the current report. The adverse reaction to COVID-19 immunization is a fascinating clinical issue. Case-specific data can be included in articles, but it is impossible to show conclusively how confounding variables affect results. It might be difficult to find the correct answer. The current study appears to be a study of the effects of vaccine aversion and appears to be highly subjective. The precise cause of a vaccination reaction may be difficult to determine due to a lack of clinical data describing the physiological and immunological status of COVID-19 vaccine recipients prior to vaccine injection.

Even when they do exist, comorbidities are rarely mentioned in clinical records. Finding the specific patho-immuno-pharmacological relationship might occasionally be challenging due to a lack of expertise. Understanding the impact of concurrent medical conditions on clinical outcomes can be challenging [2]. The least important factors are genetic ones [3]. It is challenging to give more details when none of the conclusions in the existing study are backed by fresh data. Finally, it may be said that the suggested “no association” can be verified. Another prospective study that controls for variables would be intriguing, though.
