Whitty says risk of “escaped mutant” virus increases with pressure from more widespread vaccination programme (i.e. not giving second dose 3 weeks after first, but 12 weeks - to double numbers getting first dose of vaccine)
Says the risk of the escaped mutant is sufficiently small when weighed against the benefit of vaccinating twice as many people asap. Vallance says all vaccination programmes put pressure on virus, and mutations increase as numbers vaccinated increases
