Government advisers on the Scientific Advisory Group for Emergencies (SAGE) have predicted that the re-opening will lead to a third wave of Covid-19.
Scientists say even if we stop mixing indoors and gather in groups of up to six people or two households outside it's a case of "when" not "if" it will happen again.
SAGE papers released yesterday suggest the roadmap could unleash a deadly third wave which could potentially be size of the second wave in January for hospital admissions.
What's more, it is almost unavoidable - despite the success of the vaccine rollout so far.
SPI-M-O said: “It is highly likely that there will be a further resurgence in hospitalisations and deaths after the later steps of the Roadmap.”
The reason for this the combination of three things together. Some people - mostly children - are ineligible for vaccination, others choose not to get a jab, and people who’ve had the vaccine don’t get 100% protection.

Imperial estimated only 44.6% of the population will be protected against severe disease by June 21, “plateauing” at 61% later in summer.
In “most” scenarios, the peak of a third wave is smaller than that of either the second wave in January 2021, or the first in April 2020.
However, there are some “plausible” scenarios given to SAGE - if there is poorer vaccine efficacy and few measures at Step 4 - where the number of hospital cases could match the 35,000-odd peak we saw in January.
Warwick has a central assumption with an admissions peak of around 10,000.
But Warwick and LSHTM’s lower efficacy scenarios both predict a late summer surge could see admissions back up to around 30,000.
