New Delhi, December 6
A meta-analysis of 23 studies, including 854 patients aged 12 to 20 years with mRNA vaccine-associated myopericarditis (rare acute heart inflammation), has found that the incidence of myopericarditis was higher in males after the second dose, adding that however, the overall cases are very low.
The findings, published in JAMA Pediatrics, a journal of JAMA Network, suggest largely low incidence rates and favourable outcomes of Covid vaccine-associated myopericarditis in adolescents and young adults.
This systematic review and meta-analysis found low incidence rate and largely favourable early outcomes of Covid-19 mRNA vaccine-associated myopericarditis in adolescents and young adults from a wide range of populations. These findings are reassuring but continued follow-up is warranted,” the researchers noted.
Last month, a study in the Journal of the American College of Cardiology found that the incidence of myocarditis, pericarditis or myopericarditis is two- to threefold higher after a second dose of the Moderna Spikevax Covid-19 vaccine when compared to the Pfizer BioNTech Covid-19 vaccine.
