I'm no expert but if the Indian variant is much more transmissible, it would infect a lot more people at once, and therefore run out of people to infect much quicker. Would this not mean the spikes in cases will be rather short lived and we would reach herd immunity quicker?
Moray is starting to see a fall in cases so this is what could have happened there.
This is a really nice point. Yes, i've seen some people suggest that moderate wave now actually could be beneficial in avoiding anything in the Autumn, insofar as it has exactly this effect of pushing immunity up. It's all a question of presumptions about infection rates and acquired immunity so it's not a guaranteed outcome, but it's a plausible route for the disease, yes.
On balance, I'd be 'watchful but not worried' about this varient. So far there's no evidence that it escapes the vaccine [added in edit - more than any other variant], at least for hospitalizations/deaths. Equally, there's not yet been sufficient infections to say conclusively that it won't be more vaccine resistant. That it is more transmissible I think is beyond doubt. In 2-3 weeks time we should know for sure whether or not it is likely to cause severe infection among vaccinated people. There's nothing to suggest it will, but I'm afraid it's a case of waiting - I think we need to be patient. The move to complete over 50 vaccination and faciliate surge vaccination seems a reasonable 'just-in-case' measure right now.
Hopefully it won't delay June 21st. If it does, I'd be surprised if it did by more than a month. What we really should be asking is why England, Scotland & Northern Ireland have not vaccinated at the rate Wales has. If we had, we might not even be seeing the moderate problems we're getting now. If Wales can do it, rUK could have done.
