In the UK Scottish schools go back on the 16th, 2 weeks ahead of schools in England. Lots of attention will be focused on how the infection rate will change. No children under age 16 will have been vaccinated.
Latest test of antibodies from either vaccines or infection are at over 90% of adult population

In England, it is estimated that over 9 in 10 adults, or 93.6% of the adult population (95% credible interval: 92.5% to 94.5%) would have tested positive for antibodies against SARS-CoV-2, the specific virus that causes coronavirus (COVID-19), on a blood test in the week beginning 12 July 2021, suggesting they had the infection in the past or have been vaccinated.
In Wales, it is estimated that over 9 in 10 adults, or 93.2% of the adult population (95% credible interval: 91.7% to 94.4%) would have tested positive for antibodies against SARS-CoV-2 on a blood test in the week beginning 12 July 2021, suggesting they had the infection in the past or have been vaccinated.
In Northern Ireland, it is estimated that around 9 in 10 adults, or 90.7% of the adult population (95% credible interval: 87.4% to 93.3%) would have tested positive for antibodies against SARS-CoV-2 on a blood test in the week beginning 12 July 2021, suggesting they had the infection in the past or have been vaccinated.
In Scotland, it is estimated that over 9 in 10 adults, or 92.5% of the adult population (95% credible interval: 91.0% to 93.7%) would have tested positive for antibodies against SARS-CoV-2 on a blood test in the week beginning 12 July 2021, suggesting they had the infection in the past or have been vaccinated.
Across all four countries of the UK, there is a clear pattern between vaccination and testing positive for COVID-19 antibodies but the detection of antibodies alone is not a precise measure of the immunity protection given by vaccination.
