Should we worry about recent post vaccination deaths in Norway? Almost certainly not.
Should we worry about recent post vaccination deaths in Norway? Almost certainly not. When elderly people are vaccinated, sadly some of them die quite soon afterwards, probably coincidentally.

Climate change and Risk Management – what should actuaries do?
How should actuaries advise their companies on climate change?

I’ve just published my annual round-up of my non fiction reading for last year here.

Vaccine trial results – how good are they? Really good.
Two vaccines – Pfizer and Moderna – have now announced the preliminary results of their Phase III trials. And it’s very good news – the results are very strong, and supported by enough data that they are almost certainly more than 90% effective (VE – vaccine efficacy), with their bestContinue Reading
How has Victoria’s crushing of its second Covid19 wave compared with others around the world? Extraordinarily well
This week everyone in Australia is celebrating Victoria’s success in smashing its second wave of Covid19. So how does Victoria’s experience compare with the rest of the world’s? Extraordinarily well. I’ve looked at every country in Our World in Data. And there are plenty that have managed to reduce a second wave of Covid19 to half or a third its original size.
