Covid-19 infection and vaccination have negligible effects on the severity of migraines, finds a study. People who perceived that their migraines worsened, those who had been infected were 2.5-times more likely to be concerned about migraine worsening. Patients who had been vaccinated were 17.3-times more likely to have this concern.

The research, published in the ‘European Journal of Neurology’, was conducted among 550 adults who had received migraine-related care at a Spanish headache clinic. About 44.9 per cent (247) patients reported Covid at least once and 83.3 per cent (458) had been vaccinated; 24.7 per cent (61) reported their migraine worsening since contracting Covid and 11.4 per cent (52) since vaccination.
