In a research conducted in Japan, women were shown to be considerably more likely than males to experience rash-like adverse effects after receiving the Covid-19 vaccination from Moderna Inc.
Between May and November last year, a study of 5,893 participants found that 22.4 percent of women had delayed skin responses following the first injection, compared to 5.1 percent of males.
According to a June 1 publication in the Journal of the American Medical Association, the symptoms were moderate and not regarded a contraindication to the mRNA-based vaccination.
According to the authors from Tokyo’s Self-Defense Forces Central Hospital, delayed skin responses that occur on or after six days following the injection have been documented as an uncommon adverse event in the United States and Europe.
However, they added that the rates appear to be higher in Japan, maybe due to a greater awareness of such symptoms in the nation. They believe the higher risk in women is attributable to weight disparities, as well as hormonal and environmental variables.
