Facial paralysis risk after mRNA vaccines no greater than other vaccines

People who receive mRNA vaccines are at no greater risk of facial paralysis than with any other viral vaccine, despite several cases being reported during early trials, according to French researchers. They examined World Health Organization adverse vaccine reaction data to compare cases of facial paralysis, spasms, and nerve disorders after mRNA shots with other viral and flu vaccines. Among adverse reactions reported for mRNA vaccines, 0.6 per cent were facial paralysis-related, compared with 0.5 per cent for other viral vaccines and 0.7 per cent for influenza vaccines.

What The Study Did: This analysis uses the World Health Organization pharmacovigilance database to explore the potential safety signal of facial paralysis after COVID-19 vaccination. When compared with other viral vaccines, mRNA COVID-19 vaccines did not display a signal of facial paralysis.
