There is much we do not know in view of recent developments regarding Covid-19.
Will those who have had the first strain discovered be immune to the new variants????
Will the vaccines be effective against the new strains?????
Will the infection rate be so great with the new strains that a full March style lockdown will be required in January???
The schools are an important part of the above and the defences required to combat the infection, However, they are only part of what is becoming an evermore complicated and serious scene.
My view would be that announcements will be made over the weekend following New Year and what will happen in the protection of the schools, the food industry, the utility and transport industries will be made then. I do not expect that to be good, but all should wait and see.
