The start of the mass rollout of coronavirus vaccines promised a clear path out of the health and economic crisis that has gripped the world for the past 12 months. The emergence of mutated strains, particularly the South African variant and concerns over the effectiveness of the Oxford/AstraZeneca vaccine against it, has shifted the debate about how straight that path might be. The question now is not how quickly we go back to normality but what kind of normality that will be. The ever-changing threat that the virus presents means that some aspects of pandemic life may be here for the medium or even the long term. Any remaining hopes for the speedy eradication of Covid-19 look fanciful.
