Coronavirus: what’s the strategy for ending lockdowns if Covid immunity lasts for just months?

Immunity to coronavirus may only last for a few months after infection, according to new research findings that point to another obstacle to rolling out a vaccine.

The percentage of the UK population who have developed Covid antibodies had fallen by a more than a quarter since June to fewer than one in 20 people in the UK as of last month, the Imperial College London (ICL) study suggests.

The researchers say the “rapid” deterioration in immunity means that any successful vaccine may need to be administered twice a year unless the jab proves more powerful than natural immunity, The Telegraph reports.

The new research was commissioned by the Department of Health and was based on an analysis of home fingerprick test samples from 365,000 adults to establish “detectable antibody levels” over three months.
