Police and antivax protesters clash outside offices of UK's medicines regulator in London

So-called 'medical freedom' protesters clashed with police outside the offices of the UK's medicine's regulator in the Canary Wharf area of London on Friday 3 September.

The Medicines and Healthcare products Regulatory Agency (MHRA) is the UK's regulator of medicines, responsible for ensuring their safety and effectiveness.

The protesters have a variety of so-called 'antivax' and 'covid-sceptic' causes, including opposition to lockdowns, 'vaccine passports', vaccination of children, and vaccines in general.
