That's after flu shots, in the year where flu shots were a misfire (they guessed the wrong strains) there were 2000 additional deaths (according to another source I'm not confident in that claims to have ONS figures but which I've not been able to confirm); for comparison the reported deaths (ie hospital only) for UK [which includes Scotland] has passed 15000 for Covid19 according to https://www.worldometers.info/coronavirus/#countries [fwiw I wrote 10,000 as that was the figure last time I looked ... but then checked the current number ...].
Happy for you to show it if this is wrong.
