NOTICE OF CHANGE
From 16 February 2022, Public Health Scotland (PHS) will no longer report COVID-19 cases, hospitalisations, and deaths by vaccination status on a weekly basis. PHS will continue to provide updates from the latest scientific analyses and reports on the effectiveness of COVID-19 vaccines. An explanation behind this decision can be found
below.

Since July 2021, Public Health Scotland (PHS) have reported COVID-19 cases, hospitalisations, and deaths by vaccination status in the weekly COVID-19 statistical report. These data were first published to help monitor the impact of the vaccination programme on the pandemic, impact on the NHS, and to help understand where to prioritise vaccination delivery. While PHS has stated that the data in the report should not be used as a measure of vaccine effectiveness, PHS is aware of inappropriate use and misinterpretation of the data when taken in isolation without fully understanding the limitations described below.

There is a large risk of misinterpretation of the data presented in this section due to the complexities of vaccination data. A blog post by the UK Health Security Agency (UKHSA), formerly Public Health England (PHE), provides a comprehensive explanation of the biases and potential areas for misinterpretation of such data. They state that a simple comparison of COVID-19 case rates in those who are vaccinated and unvaccinated should not be used to assess how effective a vaccine is in preventing serious health outcomes, because there are a number of differences between the groups, other than the vaccine itself, and these biases mean that you cannot use the rates to determine how well the vaccines work
