Covid-19 vaccines: alert new side effect in doses of Pfizer – Health

This week, the World Health Organization (WHO) admitted that there have been cases of myocarditis (inflammation of the heart muscle) in people who had just received mRNA vaccines (Pfizer, Moderna) against covid-19. The European Drug Surveillance Committee (PRAC) also explained that the Pfizer’s vaccine causes dizziness and AstraZeneca’s cutaneous vasculitis.

The WHO stressed that these are very rare situations and generally of a mild nature. Despite this, given the reappearance of reports and news about the relationship between vaccines and coronary problems, Kate O’Brien, director of the WHO Department of Immunization, assured that “there is no evidence of a relationship between vaccination and heart attacks.” She also warned that Covid-19 itself can cause heart problems in the body, including coronary attacks and strokes.

The PRAC has begun to consider dizziness as a side effect of the Pfizer vaccine that can appear within 24 hours of injection. The Spanish Agency for Medicines and Health Products (Aemps) also points out that it is an “infrequent” adverse reaction.

Alert! New side effects in doses of Pfizer have been reported, including myocarditis, dizziness, and cutaneous vasculitis. Although these side effects are rare and generally mild, the WHO warns that the benefits of vaccination against covid-19 outweigh the potential risks.
