The Government has released further details about which fully-vaccinated workers may be exempt from Covid isolation.
On Thursday, Downing Street published it's list of 16 sectors which could continue working after completing daily tests rather than quarantining after coming into contact with a positive case.
These included energy, civil nuclear, digital infrastructure, food production and supply, waste, water, veterinary medicines, essential chemicals, essential transport, medicines, medical devices, clinical consumable supplies, emergency services, border control, essential defence outputs, and local government.
The Department for Environment, Food and Rural Affairs (DEFRA) has now expanded on this further, outlining the positions the exemptions would apply to.
It said the exemptions would be "subject to all other mitigation options being exhausted".

The roles include:
Agri-food chain:
• Manufacturing maintenance engineers, quality assurance technicians, and highly skilled supervisors
• Specialist reach truck drivers - only where the use of this type of truck is essential in the movement of critical goods
• Official vets, meat hygiene inspectors, poultry health inspectors, environmental health officers and certifying support officers necessary for preventing immediate risk to food safety or animal welfare in processing plants
Waste:
• Staff essential to the removal and processing of healthcare, hazardous, or municipal waste
• Staff essential to the running of incineration plants
• Landfill operators

Water and wastewater:
• Water engineers, staff/contractors working on repair of mains/supply interruption, chemical and technical specialists, emergency response practitioners, and control room staff whose immediate attendance at work is essential to maintaining critical services
Veterinary medicines:
• Batch testing laboratory staff and qualified persons essential to the batch release of medicines
• Laboratory staff essential to the production of veterinary medicines
Incident response and prevention:
• Government vets and official veterinarians responding to animal disease outbreaks or cases of serious animal health/welfare concern
• Environment agency staff operating the Thames Barrier and other critical flood defence assets, and environment agency staff on response teams in regional areas across the country to ensure effective protection of life and property in the event of a flood or other major incident
• Navigation authority staff whose roles/tasks include essential maintenance on assets with high consequence of failure and/or essential health and safety activity which mitigates risk of loss of life
Those who work in the roles must remain at home when not working and return to quarantine if they receive a positive result - as long as they have been doubled jabbed and it's 14 days after the second dose.
The exemptions will run until August 16.
