Does SARS-CoV-2 vaccination affect the immediate effect of botulinum toxin? First impressions

Abstract

Background: The SARS-CoV-2 infection has spread worldwide rapidly since its identification at the end of 2019. Globally, until April 2021, there have been more than 150 million confirmed cases of Covid-19, including over 3 million deaths. Therefore, a race was promptly started to produce an effective vaccine against the new virus. Botulinum toxin injection remains the leading non-surgical cosmetic procedure worldwide, with a high rate of efficacy and patient satisfaction. Aims: This study aims to analyze the association between the SARS-CoV-2 vaccine and the immediate botulinum toxin response. Materials and Methods: This was an observational, retrospective, and multicenter study. Data were collected between April and June 2021, and a medical record review of 71 patients from 27 to 76 years old treated with botulinum toxin injection. Results and Conclusion: There were no meaningful changes in the immediate outcome of patients vaccinated for Covid-19 and botulinum toxin. However, it is vital to underline that follow-up and further studies are needed to define whether the Covid-19 vaccine can alter the duration of effect and efficiency of the botulinum toxin.
