Spain's large-scale study on the coronavirus indicates just 5% of its population has developed antibodies, strengthening evidence that so-called herd immunity to Covid-19 is 'unachievable,' the medical journal the Lancet reported
Madrid Spain's large-scale study on the coronavirus indicates just 5% of its population has developed antibodies, strengthening evidence that a so-called herd immunity to Covid-19 is"unachievable," the medical journal the Lancet reported on Monday.
The findings show that 95% of Spain's population remains susceptible to the virus. Herd immunity is achieved when enough of a population has become infected with a virus or bacteria -- or vaccinated against it -- to stop its circulation.

At present, herd immunity is difficult to achieve without accepting the collateral damage of many deaths in the susceptible population and overburdening of health systems," the report reads.
