Where do you get that anywhere in India is highly vaccinated - it really is not the case at all and especially when delta hit india.
You do seem to think you know a lot about the uk? We have 80% first doses and 58% second doses - our over 60 rates are very very low, so our vaccines are working, our hospitalisations are low, we are finding that those going into hospital are less poorly, and are often in for a day or two and then leaving - we have 10,000 cases a day rather than 2,000 a day 6 weeks ago yet hospital rates are not going up anywhere near the expected rate and long May it continue.
yes we have kept restrictions on personal and social life - yet 20,000 Scotland fans went to london and partied, we have full houses at formula one and golf coming up, full capacity at Wimbledon, 45,000 at the football - so our restrictions seem to be just penalising the individual rather than corporate abd sporting events - so hey people can gather for events that are good for our profile and for middle class sporting events - but hey we can’t have more than 30 at weddings until Monday and they can’t dance and they can’t sing even when more can attend - we can’t have more than 6 people in our homes, we aren’t allowed to leave our country basically without hoop jumping and we are testing a million people a day, schoolchildren twice a week, surge testing everywhere etc
I know where I would rather be! Your country have a greater urge for normality than we will ever have, you will to overcome this is greater (imo), so many people in the uk are still very very afraid - yoy will be in a much better position than we are
