It’s a familiar refrain of the past 6 months: “When will we get back to normal?” Its premise is that once a vaccine arrives or enough people have had Covid-19 we will be immune from its terrible effects. But new evidence on how our bodies combat the virus is casting doubt on the prospects for long-term immunity.
The Guardian’s science editor, Ian Sample, tells Anushka Asthana that one study at King’s College London showed that antibodies needed to combat the virus fade quickly in patients who have previously tested positive for Covid-19. It is results like this that could have huge implications for the development of a coronavirus vaccine as well as work being done on therapeutic treatments.
If recovery from Covid-19 or a vaccine do not provide long-term immunity, what does this mean for the prospects of ever getting back to pre-crisis normality?
