| Summary: | 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.
