Early Assessment of COVID-19 epidemiology and Vaccine/anti-viral Effectiveness (EAVE II)

Lead Research Organisation: University of Edinburgh
Department Name: UNLISTED

Abstract

Scotland is an ideal place to carry out this research as there is a unique reference number for every individual. This makes it easy to link together different health datasets and construct an electronic cohort based upon data from 250 general practices and 1.2m individuals (22% of the population). Such a large cohort, gives wide regional coverage and permits investigation of subgroups such as children aged under 5 or adults over 65.
These data are already being collected for routine care - information on GP consultations, prescriptions, out of hours’ consultations, use of accident and emergency and hospital admissions. It also includes laboratory tests to diagnose a person with coronavirus and specifically COVID-19. Individuals will be having routine blood tests and a sample of unused blood will be stored and eventually tested for the presence of COVID-19 antibodies to work out the proportion of the population exposed during the epidemic. We will also sequence virus genomes from a sample of patients. The analysis of these data is carried out in a safe haven using anonymised data so that individuals cannot be identified.
This cohort will be followed up to monitor the progress of the COVID-19 epidemic and to evaluate which interventions are effective for treating and preventing the virus.

Technical Summary

This COVID-19 Rapid Response award is jointly funded (50:50) between the Medical Research Council and the National Institute for Health Research. The figure displayed is the total award amount of the two funders combined, with each partner contributing equally towards the project. Some additional funds were added in January 2022 to be paid by NIHR only.

EAVE (Early Estimation of vaccine and Anti-Viral Effectiveness) was a NIHR-funded project on pandemic influenza, which created a Scotland-wide cohort of 227,000 individuals recruited from 40 general practices together with stored serology samples from 1,000 individuals. EAVE established a national electronic cohort though linking health data sets from general practice, prescribing, hospitalisations and virology testing using the unique Community Health Identification (CHI) number for residents of Scotland. We plan to repurpose and expand this cohort to collect electronic data from 1.2m individuals living in Scotland to study COVID-19. We will augment the cohort by collecting and storing residual sera samples and by sequencing virus from patient specimens. Both of these, are being taken as part of routine care from a sample of these individuals.
We will track the progress of the COVID-19 epidemic in near real-time using the EAVE II cohort. We will be able to model the full course of the epidemic from genome sequence data. Once a serological test becomes available we will be able to refine this model and provide precise estimates of the attack rates in different sub-populations, and accompanying hospitalisation and fatality rates. EAVE II will help to identify the clinical features of the epidemic and, in due course, provide estimates of the effectiveness of any vaccines and anti-viral therapies deployed.
Ethical and Privacy Committee approval has previously been given for the EAVE study and we anticipate the same approvals will readily be obtained for this follow-on study.

Guideline Title Deferral of fertility treatment for patients who are not vaccinated against COVID-19 - Review
Description COPS impact on policy
Geographic Reach National 
Policy Influence Type Citation in clinical guidelines
Impact In Jan (without any input from us) the CMO in Scotland wrote to Health Boards recommending that fertility treatment for women who had not received COVID-19 vaccination should be paused/deferred until the impact of Omicron in pregnancy was clearer. The decision was based on the high levels of infection at that time, and the known higher risks of adverse pregnancy outcomes in unvaccinated women infected with previous SARS-CoV-2 variants. Following this, the Scottish Government COPS to contribute to a paper outlining the latest evidence on this to inform a planned review of the recommendation. The latest COPS figures were provided in March 2022. Evidence on the impact of Omicron in pregnancy was very limited due to the short follow up time, but the COPS figures for Dec 2021 and January 2022 suggested that critical care admission rates for pregnant women with Omicron were lower than those seen for women infected with previous variants. Considering all the available evidence, the CMO wrote to Boards again in March 2022 recommending that, whilst all women preparing for fertility treatment remain strongly encouraged to get their COVID vaccination, the pause in treatment for unvaccinated women was no longer required.

Impact Early national data suggested that Omicron is associated with a two-thirds reduction in the risk of COVID-19 hospitalisation when compared to Delta and early decisions in the UK and devolved Governments about how to respond to the Omicron wave were based on these early signals in the data. Guidance was updated for working from home, masks in schools and in public places, masks on public transport and a renewed vaccination campaign. These results also contributed to public awareness with significant media coverage: https://www.theguardian.com/world/2021/dec/23/good-news-is-omicron-may-be-less-severe-bad-news-its-surging-faster https://www.thenational.scot/news/19804609.covid-scotland-nicola-sturgeon-responds-latest-encouraging-omicron-data/

Impact The Chief Scientist Office has continued to lead high level discussions with Scottish Government and NHS colleagues about the major benefits of using near real-time healthcare data in research beyond the acute phase of the COVID-19 pandemic. These discussions have continued and are being prioritised despite a change in the Chief Scientist for Health during this period. The Chief Scientist Office agrees that there is a key need for ongoing health surveillance permissions and infrastructure in Scotland, to support policymaking around areas such as other infectious diseases, other health hazards, antimicrobial resistance and non-communicable diseases of major health burden, as well as to provide ongoing whole system intelligence on the Scottish health and care system.

Title Sharing code on github 
Description We regularly update code (https://github.com/EAVE-II). Health data for our research is stored securely but separately in Trusted Research Environments in England, Scotland, Wales and Northern Ireland. By pooling the number of cases across different parts of the UK, we can create a big enough dataset to analyse rare events. Shared code facilitates common data analysis protocols across different Trusted Research Environments which means that we can perform analyses using much larger samples but without sharing actual data between research teams. 
Type Of Material Improvements to research infrastructure

Impact Our recent paper PLOS Medicine paper (doi.org/10.1371/journal.pmed.1003927) "First dose ChAdOx1 and BNT162b2 COVID-19 vaccinations and cerebral venous sinus thrombosis" is an example of impact from this method. There were not enough people in Scotland who had experienced CVST after a first dose of vaccine for us to analyse the data in a reliable way for this condition. By pooling the data across Scotland, England and Wales to form a sample of £11.6m people, we could create a big enough dataset to analyse possible links with vaccination, without sharing individual data between countries. We were able to show that there is a very small increased risk of CVST for people who had a first dose of the Oxford-AstraZeneca vaccine. We did not find any link between CVST and the Pfizer-BioNTech vaccine.

PI Contribution We led this partnership to access routine healthcare data and use common protocols to understand how safe COVID-19 vaccines are and how well they work across the UK
Collaborator Contribution Our partners looked for patterns in health records for the populations of England, Northern Ireland and Wales relating to COVID-19 vaccines, and we worked together to develop common data analysis protocols.
Impact We were the first group in the world to show using national routinely collected health data that having a first vaccine dose gives very good protection against COVID-19 hospital admission. Between 8 December 2020 and 15 February 2021, we studied over 1.3 million vaccinated people in Scotland. In a follow-on analysis, we found that between 8 December 2020 and 14 April 2021, less than one in 2000 vaccinated people in Scotland had severe COVID-19. This is despite high background levels of infection. Using common analysis protocols, we were able to coordinate a UK-wide analysis with our partners to understand how long vaccine protection lasts. At the request of one of the UK's Chief Scientific Advisers, we used data to look at side effects in the blood from the first dose of a COVID-19 vaccines. We did not find any link between the Pfizer-BioNTech vaccine and bleeding or blood-clotting side effects. We did find in some people given the Oxford-AstraZeneca vaccine a slightly increased risk of a condition known as 'idiopathic thrombocytopenic purpura' (ITP) which increases the risk of bleeding disorders. In our Scottish analysis, we were not able to find a link between the COVID-19 vaccines and a very rare side effect in the brain called 'cerebral venous sinus thrombosis' (CVST). This may have been because the number we studied in Scotland was too small to find such a rare event. To address this, we repeated the analysis in England and Wales and brought results together with the Scottish data into a single analysis of 11.6 million people. We found a slightly increased risk of CVST (0.25 extra cases of clots per million people) in the 28 days after a first dose of the Oxford-AstraZeneca vaccine. This is very, very low compared with the risk of COVID-19 hospitalisation and death in people who have not been vaccinated. We did not find any link between CVST and the Pfizer-BioNTech vaccine. In Northern Ireland, our partners looked at vaccine uptake in people having treatment for mental health disorders. When looking at their healthcare records, it seemed that adults taking medication to aid sleep, anxiety or psychosis were less likely to be vaccinated than the general adult population. We also looked at whether healthcare staff in Wales had been vaccinated. We found that overall, a high number of staff did have their vaccines but the numbers vaccinated depended on their age and what jobs they did. We have shown that vaccines prevent or shorten COVID-19 outbreaks in care home residents in Northern Ireland. We are looking at how well and for how long vaccines protect healthcare professionals in Wales, and are currently coordinating a UK-wide analysis to understand how long vaccine protection lasts.

PI Contribution Project 'Use of national linked healthcare, serology and viral genomic data to identify and characterise post-second and -booster dose vaccine breakthroughs at a population level' was funded from the NCSi grant and led by the University of Edinburgh. The project aimed to undertake a national prospective population-based cohort using routinely collected data across Scotland, with independent replication across the UK Nations' national surveillance datasets. Descriptive analysis was carried out to build a picture of which people have post-vaccine breakthroughs. These results were evaluated in terms of people's immune response after vaccination, using data from serology where available and analysis of how long this protection lasts. Following this, the risk of experiencing vaccine breakthrough for particular groups was calculated. Also, vaccine breakthroughs in terms of viral variant, vaccine type, and number of doses were evaluated. Dialogue with colleagues in NI and QUB led to greater understanding of the challenges of using GP data for research purposes, and led to further specific work in this area.
Collaborator Contribution QUB's resources accessed and analysed Norther Ireland data for the 'Use of national linked healthcare, serology and viral genomic data to identify and characterise post-second and -booster dose vaccine breakthroughs at a population level' project.

Collaborator Contribution The University of Birmingham (UoB) has been awarded up to £6,674,199 on behalf of UKRI, funded as part of the COVID-19 National Core Studies (NCS), for "Phase 1 COVID-19 Immunity - National Core Study (Phase 1 IMM-NCS)" to coordinate research programmes and infrastructure to ensure key questions on immunity are being answered from basic understanding of the immune response, through duration and nature of natural infection and vaccine induced immunity in clinically at risk and general populations. By working collaboratively we draw fresh insights and increase our collective understanding of how to accelerate control of the COVID-19 pandemic.
Impact This work is at an early stage, having only began in December 2021. Our objectives are to: 1) Estimate the frequency of post-vaccine breakthroughs from linked electronic health records and viral genomic data in Scotland in near real-time. 2) Characterise the demographic, ethnic, socio-economic, immunological and clinical features of post-vaccine breakthroughs. 3) Investigate how these risks vary by vaccine dose, vaccine type, and viral variants. 4) Develop and internally validate a prediction model to assess predictors for post-vaccine breakthroughs. 5) Analyse viral variants, mutations and lineages in post-vaccine breakthroughs, and compare these to viruses in the general population over the same time interval. 6) Replicate the above findings using research-ready national linked surveillance datasets across the other UK nations.

Results and Impact Road to recovery: the impact of the pandemic on Scotland's labour market.
The COVID-19 Recovery Committee launched this inquiry to consider what impact COVID-19 has had on long-term illness and early retirement as drivers of economic inactivity.
Professor Sir Aziz Sheikh gave evidence that the pandemic has shown that Scotland has the potential to be a world-leader in using health data to inform public policymaking, including policies aimed at tackling economic inactivity and its underlying causes. The Committee heard in evidence that the biggest barriers to realising this ambition appear to be a lack of "instruction, resources and permissions". The Committee seeks clarification from the Scottish Government on its response to this evidence, including what amount, it is investing in the advances made in health data analysis during the pandemic in wider policy areas, particularly initiatives to support the preventative health agenda and open access public health data.
