FOI Reference: FOI/2021/3408
You asked
I request your current definition as of today, 21 December 2021, of what the precise definition of the word "unvaccinated" is for your various coronavirus reports.
I have read your response to FOI Ref: FOI/2021/3099 but that does not include any mention of the 14-day period after the booster vaccination.
We said
Thank you for your request.
The definition of unvaccinated is someone who has not received any vaccination dose.
Our currently published data (up to 31 October 2021) for our publication Deaths involving COVID-19 by vaccination status, England do not include booster vaccinations therefore if someone has received a booster vaccination they are currently included in a second dose vaccination category.
Further updates will include a booster vaccine category for people who have received a booster vaccine. This may be split by time since the booster dose if the number of deaths allows the calculation of accurate mortality rates.
