France Recommends Single Vaccine Dose For People Who Have Had Covid

Its public health authority said that people who had previously been infected with Covid-19 develop an immune response similar to that bestowed by a vaccine dose.

France on Friday recommended that people who have already recovered from Covid-19 infection receive a single vaccine dose, becoming the first country to issue such advice.

Its public health authority said that people who had previously been infected with Covid-19 develop an immune response similar to that bestowed by a vaccine dose, and that a single dose after infection would likely suffice.
