      And a marginal reduction after 2 doses. Lab studies of pseudovirus and live virus neutralisation data (not presented) from multiple laboratories now strongly support this.

      And we’re back... Ok starting with one of my favourites - sequencing coverage Over 60% of cases being sequenced (we had to extend the y-axis this week 😁) I’ll say it again - the UK 🇬🇧 is a world leader in genomic sequencing. No other country can compare with the work we dopic.twitter.com/g56rJQ3pED

      58% of all sequenced this week are B.1.617.2 You can see below how B.1.617.2 (purple) is replacing B.1.1.7 (light pink) Another interesting feature is that it’s also outcompeting most of our other VOC/VUI which are fewer & fewer new cases....pic.twitter.com/gwHXeLdMNe

      In a surprise to exactly nobody who has been paying attention, B.1.617.2 is now increasing and slowly replacing B.1.1.7 in regions... Though a lot of regional variation still Yorkshire & Humber is an outlier with their new variant AV.1 making a large % of variant cases therepic.twitter.com/xGHwGADrXU

      Secondary attack rates (the % of all close contacts of a case that go on to be infected) Transmissibility increase now growing - focussing on non-travel related (community cases) 13.5% for B.1.617.2 vs 8.1 for B.1.1.7 67% increased transmissibility, up from 50% last week 😬pic.twitter.com/mPei7Jv6nN

          As always full credit to the amazing @meera_chand and a whole slew of PHE staff and academic partners who put this together and constantly add more analyses on a weekly basis to build this picture & inform the pandemic response 👍 Ps Hope all ok with the timing this week 😉pic.twitter.com/b7FvfTrKcy

          Complete rookie here but would we not expect the secondary attack rate to be higher now restrictions have been eased a fair bit? Would that not make comparing overall attack rates of B.1.617.2 since April vs B.1.1.7 since December a bit unfair?

          The actual Rt numbers in the Indian variant hotspots don’t suggest transmissibility anywhere near that number...

          Is there anyway to split contacts into vaccinated and unvaccinated, and if so does the 67% still hold?
