In very rare cases, vaccines can cause nervous system disorders or exacerbations of neurological diseases. However, the authors of the review in the journal stressed that the benefits of vaccines significantly outweigh the possible risks Nature Reviews Neurology.
Scientists have analyzed studies of neurological complications of various vaccines. Doctors’ reports show that live vaccines based on weakened pathogens can cause nervous system disorders. For example, polio virus from an oral vaccine can mutate into a more contagious form and cause paralytic polio. The measles vaccine very rarely causes brain inflammation.
COVID-19 vaccines can cause Guillain-Barré syndrome, which is accompanied by immune and neurological disorders. However, coronavirus infection itself can also cause this condition and the risk is much higher.
Narcolepsy, which involves sudden sleep onset, was associated with the 2009 swine flu vaccine.
It has also been suggested that the vaccine may also affect people with chronic nervous system diseases. No association was found between vaccination and relapse in patients with multiple sclerosis and epilepsy. Even COVID-19 vaccines have been beneficial in cases of severe disability due to multiple sclerosis. A slightly increased risk of hospitalization was seen in patients with myasthenia gravis after ChAdOx1 nCoV-19 coronavirus vaccination. The cause of this is unknown.
The review highlights the importance of vaccines in preventing serious infections and associated neurological diseases. The authors acknowledge that rare neurological side effects are possible, particularly with live vaccines. Most people do not need to worry about vaccination, except for those who have experienced a rare side effect.
The scientists concluded that improving data collection on side effects will be important to increase vaccine safety and confidence in the future.
