According to a recent study, the world needs improved vaccines and immunization campaigns since, in 2021, before the Omicron wave, 50 to 70% of children under the age of 19 were susceptible to SARS-Cov-2. Findings show that by the end of 2021 and before the Omicron wave, between 50 and 70 percent of children worldwide were still susceptible to SARS-CoV-2 infection, underscoring the need for more potent vaccines and greater vaccination coverage among children and adolescents, particularly in developing countries and among minority ethnic groups.
Additionally, it found that estimates of the global seroprevalence ranged from 7.3% in the first wave to 37.6% in the fifth wave to 56.3% in the sixth wave. When dividing the total number of children tested by the total number of children who tested positive for particular anti-SARS-CoV-2 antibodies, the result is known as seroprevalence.
Affluent nations with adequate vaccination supplies have seen an increase in the number of children who require more critical care
The Western Pacific region had the lowest seroprevalence, between 0.01 and 1.01 percent, and South East Asia had the highest, ranging from 17.9 to 81.8%. According to the report, experts investigated international and pre-printed scientific databases between December 2019 and July 10 of 2022 as part of a systematic review and meta-analysis. The study comprised 247 publications containing almost 302 datasets totaling 757,075 kids from 70 countries and six regions specified by the WHO.
The analysis found that 144 records came from Europe and 14 from the Western Pacific. Poor vaccine campaigns were the product of the pre-Omicron period paired with concerns about the safety of youngsters receiving vaccines. The study found that affluent nations with adequate vaccination supplies, such as the US, England, and Germany, have seen an increase in the number of children who require more critical care since the development of Omicron.

Scientists said, “We aimed to provide estimates for the proportion of children with detectable antibodies and to identify sources of heterogeneity in SARS-CoV-2 seroprevalence in children for various regions of the world”.
