Joint Biosecurity Centre

The Joint Biosecurity Centre (JBC) is a scientific body which seeks to advise United Kingdom government policy as part of the response to outbreaks of COVID-19, such as on testing deployment, international travel, and the UK 'COVID-19 alert level'. Its existence was announced by Prime Minister Boris Johnson in May 2020. The body has been part of the UK Health Security Agency since the establishment of that agency on 1 April 2021. 
Leadership.
Tom Hurd held the chief position from May 2020 to June 2020, when he was replaced by Dr Clare Gardiner.
On 17 October 2020, it came to light that Dr Thomas Waite was in charge of the Health Protection bureau at JBC.
History.
In October 2020, it came to light that one of the responsibilities of the JBC was "the local lockdowns enforced on millions of people across the country".
The JBC made the news in October 2020 when it was the subject of discussion over the secrecy to which it was entitled. Certain MPs and scientists then demanded that the minutes and the membership of the JBC be published.
On 17 October 2020, it came to light that the JBC was responsible for decisions to impose movement restrictions in London, York and other areas. Certain MPs were upset that the JBC failed to publish neither its analysis nor its argument. Even its premises were shielded from view by its Health Protection bureau chief.
