This five point-plan, set out in the COVID-19 Response: Summer 2021[footnote 3], will help us to manage the risks of living with the virus on our careful and cautious pathway back to normality.
Reinforce the country’s vaccine wall of defence through booster jabs and driving take up. Government will encourage vaccine take up among young adults and those yet to be vaccinated, ensure all adults have had the opportunity to receive two doses of the vaccine by mid September, and offer booster jabs to the most vulnerable subject to final advice from the JCVI.
Enable the public to make informed decisions through guidance, rather than laws. Government will reopen the remaining closed settings and remove regulations from 19 July, provide guidance for individuals, businesses, and those who are Clinically Extremely Vulnerable on the behaviours that can help to protect everyone. Government will look to operate public services in a way that supports everyone feeling safe to access them, and work with businesses to the same effect.
Retain proportionate test, trace and isolate plans. Government will keep our testing system in place; continue to offer free lateral flow tests to help people manage their personal risk; maintain current domestic isolation requirements until 16 August before introducing an exemption for fully vaccinated contacts and under 18s; and maintain support for self isolation, with practical and financial support available until the end of September.
Manage risks at the border and support a global response to reduce the risk of variants emerging globally and entering the UK. Government will continue to operate a traffic-light system for international travel, reassessing the red, amber and green lists this week, and every three weeks, through the summer; remove quarantine requirements for fully vaccinated UK travellers returning from amber countries from 19 July, while retaining PCR testing crucial for identifying new variants; and accelerate global vaccination by prioritising access to vaccines in developing countries.
Retain contingency measures to respond to unexpected events, while accepting that further cases, hospitalisations and deaths will occur as the country learns to live with COVID-19. Government will continue to monitor the data on a regular basis to ensure there is no danger of the NHS facing unsustainable pressure; work with local authorities and provide national support to local areas that need an enhanced response to COVID-19; and maintain contingency plans for reimposing economic and social restrictions at a local, regional or national level if evidence suggests they are necessary to suppress or manage a dangerous variant. Such measures would only be re-introduced as a last resort to prevent unsustainable pressure on the NHS.
