Can COVID-19 vaccines relieve severe tension-type headache and migraine?

ABSTRACT

Chronic headache is a frequent disorder that can cause a significant deterioration in the quality of life of the affected person. The COVID-19 pandemic is compelling all countries to develop a complete vaccination protocol for the entire population. In this article, we present 8 clinical cases of patients suffering chronic headache which resolved completely or partially after vaccination. Five patients had migraine, 2 had a post-viral headache typical of COVID-19, and one had a headache induced by sexual activity. Resolution was complete in 3 cases, almost complete in 2 others, and a great improvement was observed in the other 3. We hypothesize that the administration of vaccines for COVID-19 can produce an improvement or the disappearance of symptoms in our patients by inhibiting synthesis of pro-inflammatory cytokines.
