BMJ (Child mask mandates harms)
“Real-world effectiveness of child mask mandates against SARS-CoV-2 transmission or infection has not been demonstrated with high-quality evidence. The current body of scientific data does not support masking children for protection against COVID-19.”
“Of the six studies reporting a significant negative correlation between masking and COVID-19 cases, five had critical and one had serious ROB [risk of bias]. Of the 16 studies failing to find a significant correlation, one (6.3%) had critical, 10 (62.5%) had serious, five (31.3%) had moderate and none had low ROB. [emphasis added here and below]”
