Teenage recipients of COVID-19 vaccines faced an elevated risk of serious adverse events, including appendicitis, after a second dose, researchers said in a new study.

Norwegian scientists observed about 496,432 adolescents aged 12 to 19 for the study, published in Scientific Reports on March 27, utilizing nationwide safety data. Many of the adolescents received a messenger ribonucleic acid (mRNA) COVID-19 vaccine from Pfizer-BioNTech or Moderna.
