Weekly COVID19 vaccination in total populations (ourworldindata.org/covid-vaccinations) increases weekly total mortality (euromomo.eu) of children 0-14 years old in January-October 2021 (unvaccinated at that period) from 23 European countries. Above 14 years, results indicate vaccine protection after week 5, which ends after about 20 weeks after vaccination, followed by adverse vaccine effects as

In those below 15 years, which are unvaccinated, adverse effects start 3-4 weeks after adult vaccination and gradually increase until 18 weeks after adult vaccination. A second wave of positive associations between adult vaccination and child mortality occurs between weeks 27-35 after adult vaccination. At the level of the whole population of children below 15 in these 23 countries, a weekly 1% increase in vaccination of adults results in 29 additional deaths of children, an 15% increase in the average weekly children death rate. Comparing health of unvaccinated children with no, one and both parents vaccinated could test whether vaccine shedding accounts for indirect vaccine effects affecting unvaccinated children, without vaccinating children. Direct adverse vaccination effects are probably stronger than indirect effects, predicting strong or extreme direct postvaccination adverse reactions in the young. Direct vaccine effects probably mask indirect adverse vaccine effects in adult populations.
