If it is spreading in schools, perhaps it is time to start vaccinating teenagers, or at the very least approve one of more of the vaccines for teenagers and aim to vaccinate them at the start of the next school year. The Pfizer vaccine has been approved for 12 to 18 year olds in the United States and EU.
If it is spreading in schools, I think it might be prudent to start the summer holidays a few weeks early.
From what I remember of my school days (>40 years ago !!) the last few weeks of the summer term were spent in doing things like day trips and school sports days rather than teaching the curriculum. If this is still the case, it wouldn't cause too much disruption to education to have an early start to the holidays, although I recognise it would cause some inconvenience to working parents.
As to the Indian variant having a greater risk of hospitalisation than the Kent one, it has been emphasised that the figure of 2.6 times is only provisional, and more data is needed before a more accurate figure can be determined.
The other thing to point out is that it is the absolute probability that matters. For example, the probability of winning 5 balls on the National Lottery is six times greater than winning 6 balls, but both probabilities are vanishingly small. As we know that vaccines are effective against the Indian variant, albeit less so that the Kent variant, the number of people who are exposed to this higher probability of hospitalisation is falling all the time. It is the number of people exposed to the probability of hospitalisation, multiplied by the probability of hospitalisation, that determines the number of hospitalisation.
Also, I have seen some reports that people who are hospitalised with the Indian variant are not a seriously ill as those with other variants, and are less likely to need mechanical ventilation, for example. So even though more people may be hospitalised, they are likely to spend less time in hospital overall, which keeps the total number of patients down, and ultimately this is what matters. I hope the government takes this into account when making decision.
So I still think that there will be some easing of restrictions on 21st June, but that some measures will remain in place for a while longer, perhaps until two weeks after all adults have been offered a first dose of the vaccine.
I also think that school staff and university students should be prioritsed for a second dose of the vaccine if they have not already had one. This is because we did see an increase in cases last year after schools and universities went back, and it would be wise to do what we reasonably can to mitigate against the risk of the same thing happening this year.
