> The point is that it does seem like this Delta variant breaks through regularly and it does seem (again, purely anecdotal) like it's v infectious. Of course the thing to emphasise is that, whilst it might break through, the vaccine still stops serious illness to a high degree.
If numbers from IHU Méditerranée are to be believed, the Indian variant is about 6 times less dangerous than the English one. Way more infectious and less dangerous, the latter part helped mutating it to the former. And that's the numbers without taking vaccination into account.
I wish medias would relay the information fully instead of spreading fear by only telling about the more infectious part. If indeed less dangerous this is a very good news that this strain is spreading more.
