We propose that a ‘Super Cohort’ - comprising of multiple existing UK Longitudinal Population Studies (LPS), including ALSPAC/Children of the 90s – is formed. The data from ALSPAC participants will be linked to whole population NHS and subsequently administrative records and rapidly used for COVID-19 (COVID) research. This work is part of UK government strategy for COVID pandemic research developed by the NHS, government officials and academic health and social science research community. The Super Cohort envisages centralised (by UK nation) sets of key NHS records which are minimised to the purpose, joined together and regularly refreshed during the COVID pandemic. All records will be stored, processed and used for research in a 'Trusted Research Environment'. This is a high security research server which is de-identified and allows researchers to access individuals (including ALSPAC participants) records without revealing individual identities. No data is allowed to exit the server, only anonymous statistical research findings can be exported. These findings will contribute to government policy development and the international understanding of COVID as a disease and the impacts of social distancing and other protective measures.
