I’ve mentioned previously that the roll out of a dose of vaccine has been associated with an increase in excess deaths (eg, here), and we seem to have seen the same effect in March.
At around the 21st March (week 12) England started to roll out the spring booster doses for those aged over 75 (and other vulnerable individuals). By the 7th April (week 14) the NHS had congratulated itself with the announcement that over 1 million doses had been given.
Here’s the data (from Euromomo) for excess deaths in England for those aged 75-85 since the start of the year:
I’ve highlighted the period where the million booster doses were delivered.
I note that we managed to get through the Omicron wave in the UK with normal levels of excess deaths in those aged 75-85, but as soon as the booster doses were rolled out we rapidly hit the threshold for a ‘substantial increase’.
Of course, it might be a coincidence — we have had rather a lot of coincidences over the last 15 months.
