Neurological adverse events are very rare after COVID-19 vaccination and less frequent than after SARS-CoV-2 infection
Incidental illnesses, including neurological conditions, occur regardless of vaccination. Individual case reports and data from vaccine surveillance systems are generally insufficient on their own to establish a causal link between these events and the vaccine, so further investigations are needed to determine whether a vaccine caused these events. Epidemiological studies show that neurological adverse events after COVID-19 vaccination are very rare, much rarer than after SARS-CoV-2 infection, suggesting that the benefits of COVID-19 vaccines outweigh this potential risk.
