Coronavirus infections in childhood and vaccine studies.

Abstract

In late December 2019, a new coronavirus (CoV) called the severe acute respiratory syndrome CoV 2 (SARS-CoV-2), which had not been detected in humans before, caused a worldwide pandemic. Owing to the highly infectious nature of this virus, it spread rapidly from person to person despite the warnings of the World Health Organization and all the measures taken by the governments. Although it has been reported that SARS-CoV-2 is more likely to infect the elderly, all age groups are susceptible to this virus, including newborns. CoV disease 2019 (COVID-19) symptoms seem to be less severe in children than in adults, but similar to the 2003 severe acute respiratory syndrome epidemic, in the COVID-19 pandemic, the number of cases and the risk of serious diseases increase as age increases. The treatment of COVID-19 is still challenging, especially in children, and the virus continues to cause death worldwide. The safest and most controlled way to effectively and sustainably prevent COVID-19 in a society is to have an effective and safe vaccine and to successfully vaccinate the majority of the population. It is possible that vaccines with safety and efficacy that have been proven in phase III trials will be effective in handling COVID-19.
