Large scale Covid-19 study in Spain suggests herd immunity not feasible

It appears as though herd immunity may not be a feasible option, according to an antibody study conducted in Spain.

A Spanish study has cast doubt on the feasibility of herd immunity as a way of tackling the Covid-19 pandemic.


The study of more than 60,000 people estimates that around just 5 per cent of the Spanish population has developed antibodies, the medical journal the Lancet reported.

It is believed that around 70 per cent to 90 per cent of a nation's population needs to be immune to protect the uninfected.

The study's authors spoke about their findings, saying that social distancing remains pivotal to any attempt to deal with Covid-19.

"Despite the high impact of Covid-19 in Spain, prevalence estimates remain low and are clearly insufficient to provide herd immunity.

"This cannot be achieved without accepting the collateral damage of many deaths in the susceptible population and overburdening of health systems.

"In this situation, social distance measures and efforts to identify and isolate new cases and their contacts are imperative for future epidemic control."

Spain was one of the countries hardest hit by the coronavirus pandemic with an estimated 28,385 fatalities.
