# Scientific Advisory Group for Emergencies

The Scientific Advisory Group for Emergencies (SAGE) is a UK Government body that advises central government in emergencies. It is usually chaired by the United Kingdom's Chief Scientific Adviser. Specialists from academia and industry, along with experts from within government, make up the participation, which will vary depending on the emergency. SAGE gained public prominence for its role in the 2020 COVID-19 pandemic in the United Kingdom.

## History

In the aftermath of the United Kingdom BSE outbreak, "the then Government Chief Scientific Adviser (Lord May) published Guidelines on the Use of Scientific Advice in Policy-Making; these have subsequently been revised, most recently in June 2010... The Government [later] developed the Principles of Scientific Advice to Government, which 'set out the rules of engagement between Government and those who provide independent scientific and engineering advice.' The Principles apply to 'Ministers and Government departments, all members of Scientific Advisory Committees and Councils [...] and other independent scientific and engineering advice to Government.' They detail principles related to roles and responsibilities, independence and transparency and openness." The May advice was updated in May 2011 in a document entitled Code of Practice for Scientific Advisory Committees (CoPSAC 2011).
"In an emergency where scientific or technical advice is required to aid the emergency response, the Government may decide that a" SAGE "is required; this decision can either be made by the Lead Government Department (LGD) or the Cabinet Office in consultation with the Government Office for Science. SAGE is usually chaired by the Government Chief Scientific Adviser... Each SAGE is emergency-specific. The swine flu pandemic was the first emergency where the SAGE mechanism was used; volcanic ash was the second."
SAGE has advised the government on a number of events, including:
* the 2009 flu pandemic
* the 2010 eruptions of Eyjafjallajökull
* the 2011 Fukushima nuclear accident
* the 2013–14 United Kingdom winter floods (3 meetings)
* the 2014 Ebola outbreak (3 meetings)
* the 2015 Nepal earthquake (1 meeting)
* the 2015–16 Zika virus epidemic (5 meetings)
* the 2018-9 Ebola outbreak (3 meetings)
* the potential catastrophic breach of Toddbrook Reservoir in 2019 (1 meeting)
* the COVID-19 pandemic (at least 105 meetings)

## Structure and function

SAGE was reported in July 2020 to consist of around 20 participants at any one given time. Participants are drawn from both academia and practice, and the participants of a particular meeting are decided upon by the British Government Chief Scientific Adviser and the Chief Medical Officer for England, depending on the expertise required. They are not generally employed by government. They do not operate under government instruction. In addition to these participants, SAGE is also attended by officials from relevant parts of government and arm's-length bodies who may contribute to discussions with relevant expertise, for instance, the UK Health Security Agency and the Chief Scientific Advisers to government departments.
The government does not have to act upon the conclusions of SAGE, and other bodies, including other sources of scientific advice, feed in to government's decisions. Only the Chief Scientific Adviser and Chief Medical Officer may speak on behalf of SAGE.
In 2020, the UK Government carried out a review of SAGE's structure in the context of the COVID-19 pandemic.
Sub-committees can be delegated by SAGE to study particular issues. During the COVID-19 pandemic, these were:
* Scientific Pandemic Insights Group on Behaviours (SPI-B)
* Scientific Pandemic Influenza Group on Modelling (SPI-M) and its the Operational sub-group (SPI-M-O); the sub-group was awarded the Weldon Memorial Prize in 2022 for its work in the COVID-19 pandemic
* PHE Serology Working Group
* COVID-19 Clinical Information Network (CO-CIN)
* Environmental Modelling Group (EMG)
* Children’s Task and Finish Working Group (TFC)
* Hospital Onset COVID-19 Working Group (HOCI)
* Ethnicity Subgroup
* Social Care Working Group (SCWG)

## COVID-19

The 2020 COVID-19 pandemic has seen an expanded role for and greater attention paid to SAGE.
Although not prohibited, until the 2020 COVID-19 pandemic, it is believed that political advisors had never attended SAGE meetings in any capacity nor is there evidence for 10 Downing Street officials attending these meetings too. It was reported that Dominic Cummings and Ben Warner had attended COVID-19 meetings. Their attendance and participation was widely criticised, in particular by other attendees "shocked, concerned and worried for the impartiality of advice".
Early in the pandemic, in April 2020, SAGE was criticised for a lack of transparency. For their security and safety, and on advice from the Centre for the Protection of National Infrastructure, the list of current members was not disclosed, although members could, and many did, reveal their own membership. Chris Whitty, speaking to the Health and Social Care Select Committee regarding the COVID-19 meetings of SAGE and the anonymity of its members, said that SAGE was "given quite clear advice from the Centre for the Protection of National Infrastructure, basically based on the fact that SAGE is a sub-committee of COBRA". Patrick Vallance argued in a letter to Parliament that scientists were protected by the anonymity from "lobbying and other forms of unwanted influence".
Membership of SAGE and its subcommittees was published on 4 May 2020. A register of participants' interests was first published in December 2020.

## Participants
### April 2020

A report in The Guardian stated that attendees at an April 2020 meeting of the group included:
Senior advisers:
* Sir Patrick Vallance, Chief Scientific Adviser (chair)
* Professor Chris Whitty, Chief Medical Adviser
Medical and scientific experts:
* Professor John Aston, statistician, Chief Scientific Adviser to the Home Office
* Dr Meera Chand, microbiologist
* Sir Ian Diamond, National Statistician
* Professor John Edmunds, epidemiologist
* Sir Jeremy Farrar, medical researcher
* Professor Neil Ferguson, epidemiologist
* Professor Peter Horby, epidemiologist
* Professor Angela McLean, mathematical biologist
* Professor Graham Medley, epidemiologist
* Dr Edward Mullins, clinical adviser
* Professor Sharon Peacock, microbiologist
* Professor Stephen Powis, national medical director for England
* Professor Andrew Rambaut, molecular biologist
* Emma Reed, emergency planner
* Professor Brooke Rogers, social psychologist
* Dr James Rubin, psychologist
* Professor Jonathan Van-Tam, influenza specialist, Deputy Chief Medical Officer for England
* Professor Charlotte Watts, epidemiologist, Chief Scientific Advisor to the Department for International Development

Political advisers:
* Dominic Cummings
* Dr Ben Warner, data scientist
Vallance has written that SAGE includes scientists and experts from more than twenty separate institutions. SAGE also contains four expert groups which may each have as low as five and as many as over forty members.
Dominic Cummings was confirmed by 10 Downing Street to have attended a 23 March meeting, but the government said Cummings was not a member of SAGE. The attendance and participation by Prime Ministerial advisors caused much criticism. It was reported that one participant considered that Cummings' interventions had sometimes inappropriately influenced what is supposed to be an impartial scientific process; another expressed shock when Cummings first began participating in SAGE discussions, in February, viewing this as unwanted political influence on what should be "unadulterated scientific data".

### May 2020

In May 2020, Professor Neil Ferguson resigned from SAGE after The Telegraph revealed he had violated lockdown rules to meet with a partner. The same day of his resignation, a list of SAGE participants was published by the UK Government, 4 May 2020. However, it notes that: "Permission to publish names was requested from all participants. Those who did not give permission have not been named." In addition: "These meetings are also regularly attended by officials from Her Majesty’s Government. These attendees have not been named."

## Criticism and developments

An April 2020 article in The Guardian written by Richard Coker cited SAGE as a potential example of "scientific groupthink" in which disagreement and/or conflicting views are minimised to reach a consensus. Although disagreement is not preferable, this may ultimately lead to potentially irrational decision-making as counter views are not encouraged.
On 24 October 2020, The Spectator, while noting that SAGE minutes are published, called for a publication of the data used by SAGE, including NHS occupancy data, that were employed by it to justify the decisions it made. The editors remarked how in France hospital occupancy data were indeed published daily, while they were told by the NHS to submit a Freedom of Information request, which can take up to 28 days.

## Independent SAGE

The questions raised about the transparency of SAGE and possible political interference during the COVID-19 pandemic raised concerns about trust in public health messaging by opposition parties and others. As an alternative, a group of scientists created Independent SAGE, chaired by Sir David Anthony King, a former Government Chief Scientific Advisor, in early May 2020 to "provide a clear structure on which an effective policy should be based given the inevitability that the virus will continue to cross borders". Later that month, Independent SAGE warned against ending lock-down prematurely in places like schools.
