5.Is it true that children were largely protected from viruses during 2020 and 2021?
In Scotland, most children did not attend school between late March 2020 and the end of the summer holidays (August 2020) and from January until March 2021. However, other than advice to open windows more often, no mitigations against airborne transmission of Covid were ever implemented in Scottish primary schools, although secondary school pupils were advised to wear cloth or surgical face masks (less effective than FFP2 masks) in class between October 2020 and February 2022. Except when schools were closed, Covid infection rates were significantly higher in children than in adults during 2021 and early 2022 (after which free Covid tests were withdrawn). Anecdotally, parents reported many children getting colds as soon as they returned to school in summer 2020. As referred to above, RSV infections in children were rampant in 2021. Except for flu not having been widespread in 2020 and 2021, it is simply not true that children overall were not exposed to viruses for a year or longer.
