After reports of rare heart inflammation cases among adolescents following the Pfizer vaccine shot, some countries have tweaked their vaccination programmes for teens. The countries have either halted administering mRNA-based vaccines to teens or giving only one dose of the Covid shots to prevent the possible rare cardiovascular side effects.
UK’s Joint Committee on Vaccination and Immunisation (JCVI) recently stopped short of advising against administering the Pfizer vaccine in healthy adolescents. The committee had said that the margin of benefit against risk is “too small” to advise on a universal programme of vaccination for healthy 12 to 15-year-old children.
While the United States has continued to administer the Pfizer vaccine to adolescents, it had issued a warning to watch for the symptoms of myocarditis, the rare inflammatory heart condition.
In July, European Medicines Agency said that it had found a possible link between myocarditis and mRNA-based Covid-19 vaccines. Pfizer-BioNTech and Moderna have developed mRNA-based vaccines which are being used in the United States on a massive scale to vaccinate the population.
