Coronavirus: Spanish study casts doubt on herd immunity feasibility
YEREVAN, JULY 7, ARMENPRESS. A Spanish study has cast doubt on the feasibility of herd immunity as a way of tackling the coronavirus pandemic, reports BBC.
The study of more than 60,000 people estimates that around just 5% of the Spanish population has developed antibodies, the medical journal the Lancet reported.
Herd immunity is achieved when enough people become infected with a virus to stop its spread.
Around 70% to 90% of a population needs to be immune to protect the uninfected.
