1 / 5Vaccines against Covid-19 are effective in preventing children and adolescents from becoming seriously ill from this epidemic.2 / 5The study, published in the journal BMJ Pediatrics Open, showed that most children are already infected with SARS-CoV-2 and are naturally developing immunity, so the additional benefit of vaccination in healthy children is minimal. 3 / 5A team led by researchers from the Murdoch Children's Research Institute in Australia has investigated the challenges of Covid-19 vaccination, particularly the spread of large-scale infections in communities in low- and middle-income countries, and the importance of immunity from infection.4 / 5The review suggests that the anti-Covid-19 vaccination campaign should be carried out alongside routine vaccines for diseases such as measles, pneumonia and diarrhea in children in low- and middle-income countries.5 / 5The study shows that although most children were infected with Covid-19 and became seriously ill, deaths due to it were rare. The researchers said that the impact of the anti-Covid-19 vaccine was limited when the infection was examined in children.
