It's a rubbish assumption though. According to the UK data (which is age stratified), unvaccinated children get infected much more often. You could say that children have strong immune systems therefore they don't get sick but only infected. Maybe vaccination for children further improves their immunity that they don't get infected either (will see if it works for omicron though). As for other people, even vaccinated easily get infected but the severity of illness is reduced.
