      NEW: lots of news recently on waning immunity against infection, but a study has now landed from Public Health England on how vaccines are faring against *severe disease & death* This chart summarises key findings, but the paper is a real goldmine, so let’s dig into more detail:pic.twitter.com/9wAiax8poJ

      First up, fresh data on protection against symptomatic infection. Key results: • We knew protection started out lower among older groups. Now we know they also see the most waning • Waning much more muted (if happening at all) among under-65s • Moderna > Pfizer > AstraZenecapic.twitter.com/N9JM2wlsKc

      Sticking with symptomatic infection, they also looked at a hot topic: the impact of the interval between first and second dose Very short intervals (3 weeks, e.g in US) produce lower protection than longer intervals (e.g UK & Canada), though note overlapping confidence intervalspic.twitter.com/YwT6XI0adf

      Quelle surprise. Three weeks was an unprecedented, extremely short interval, chosen to speed up trials, but then got stuck because people who knew that it would threaten robustness were not loud enough while others yelled "Follow the Science!" See thread.https://twitter.com/zeynep/status/1356416693954871298 …

      (Also is three weeks too short for a robust response? It increasingly seems that non-standard interval was chosen mostly to speed up trials. Randomizing three weeks and, say, five or six weeks and comparing outcomes might be useful and seems pretty low risk?).

          So the charts he posted were based off UK data. What does the waning look like in the US where we used 3/4 weeks between doses rather than 8? Do his conclusions apply here?
