Study says 50-70% of those below 19 still susceptible to SARS-CoV-2

Fifty to 70% "children" below 19 years globally were susceptible to the SARS-CoV-2 infection by the end of 2021 and before the Omicron wave, showing a need for more effective vaccines and better vaccination coverage, according to a study. It also found that worldwide seroprevalence estimates varied from 7.3 per cent in the first wave of the COVID-19 pandemic to 37.6 per cent in the fifth wave and 56.6 per cent in the sixth wave.
