U.K. Study Shows Maskless Kids *Less Likely* to Test Positive for Covid

The U.K.’s Office of National Statistics this week released a report that contained some blockbuster findings, particularly on Covid testing and the masking of schoolchildren.

Right off the bat, the ONS notes that people who have been vaccinated are more likely to test positive for Covid than those with prior infections.

“Our latest data for the fortnight ending 31 December 2021 show similar conclusions to our last publication, namely”:

those who reported receiving one of any coronavirus (COVID-19) vaccines 15 to 90 days ago, a second Pfizer vaccine 15 to 180 days ago, or any three vaccinations (including booster vaccinations) were all less likely to test positive than those who are not vaccinated; however, these effects are smaller than what we have seen previously

those who had previously been infected with COVID-19 continued to be less likely to test positive than those who had not, however this effect was smaller than we have seen in the past

those who were previously infected during the period when Delta was dominant were even less likely to test positive again than those infected in the Alpha dominant or pre-Alpha period¹
