If the uk had vaccinated under 12s sooner the recent death rate would have been lower I think. A significant number of people have died over recent months largely due to the virus ciruclating heavily and unnecessarily amongst this age group. Not to mention the number of people admitted (and thus the strain on services), the numbers of people with long covid (which remains ambiguous and unquantified but seems not to be small), the huge number of school and work days lost recently due to quarantine and illness (and the stress caused) and the immense amount of testing the population undergoes regularly. Living freely in the UK in covid doesn't seem all that free to be honest
But in saying that at the cost of all the above and due to the UKs (absolutly necessary and reactive) response of speeding up the booster campaign, the UK should hopfully avoid further disaster that may be seen elsewhere in Europe this winter. Also the uk vaccinate young and old with flu vaccines whereas only vulnerable and elderly people are vaccinated in many European countries, so flu may less of an issue in the UK.
But then Europe is not all the same. Take Spain insted if Austria in comparison for example. They had a significant relaxation of the rules (mask mandate remained though) and saw a big rise of infections of in the early summer months (esp in younger kids i think). But by September when school started they moved quickly and most over 12s were vaccinated. Combined with mask mandates and ventilated classrooms (easier because of the weather), life in spain has been close to normal (aside from indoor masks for over 6's and bubbles at school). Schools have been open in person all year, extracurriculars as normal. In our school of 2000 kids, 1 class of 25 kids had to quarantine every few weeks (since sept) due to a covid case and they are virtual schooled by their teachers in this time. Also I think as such we have all had to do about 1 or max 2 covid tests (lft or pcr) each since the pandemic began.
But then again Spain's numbers are rising (not like eastern europe) and the potential of winter being difficult remains a threat. I think spain's most recent rate is 120 cases per 100000 vs englands 450 (please correct me if that's wrong ). The booster campaign hasnt been as urgent as in the UK so its going a lot slower (very slow) and that could definitely be a problem in a few weeks or months, especially immunity wains.
It's all been going in waves... a country does well, it relaxes.. takes foot off the breaks.... wave rises again.. I do believe there is going to be a point (and it will come before there is any need to mandate vaccines) though where as the german minister said most people will be vaccinated, recovered or unfortunately dead - and the question is how to minimise the dead number whilst (maintaining quality of life)- by natural infection or vaccination. The natural infection route that the UK has taken since september has most definitely not been without costs and how spain handles its future with vaccines while gently controlling infections (through masks and passports) could really inform whether the UK made some misteps or whether the death rate, admissions it faced are just inevitable (and better gotten over before winter).
