Vaccines in UK are not mandatory. There is an exemption on evidence of medical reasons and the Supreme Court recognises at common law that denial of free and informed consent is a self certified medical reason. See Montgomery v Lanarkshire [2015] UKSC 11  https://www.supremecourt.uk/cases/docs/uksc-2013-0136-judgment.pdf …In R Wilkinson v Broadmoor : [2001] EWCA Civ 1545

In that case Lady Justice Hale, Supreme Court President, confirmed that forced medical procedure without informed consent "may be sued in the ordinary way for the (common law) tort of battery".  https://www.bailii.org/ew/cases/EWCA/Civ/2001/1545.html …In the judgement it was held that acting under statutory authority provides no defence, therefore the Employer will be guilty of coercion on the threat of battery with regards to unlawful dismissal if express evidence of denial of informed consent are unlawfully rejected.This will result in a breach of contract and also a Tort that can be sued.
