The reason the UK got the response to the rare clots that likely are caused or exacerbated by $AZN #covid vaccine “right” was exactly the same as why they got the decision to increase spacing between 1st and 2nd doses spot on: recognising the cost of doing nothing

#DrugBaron set out the logical framework for acting in the face of limited information here: https://drugbaron.com/one-dose-or-two-what-the-debate-about-covid-vaccination-teaches-us-about-science-and-its-limitations/

And exactly the same framework applies to the decision to continue giving (and receiving) an $AZN vaccine with a known but miniscule risk

The pervasive mentality of “its better to be conservative when we dont have enough data” kills people in a pandemic - because the landscape has shifted from our “normal”

Many very smart people have been slow to recognise that (and scientists may be the worst at it)

Its a bit like people who wont wear masks because its so hard to generate robust, unequivocal proof they work

The absence of evidence is never evidence of absence
