Single-dose vaccine may be effective for Covid-19 survivors: Study

Amid the ongoing COVID-19 vaccination drive across the globe, a study suggested that the second dose of coronavirus vaccine may not be needed for those who have recovered successfully from a prior COVID-19 infection. As per the report, the research involved more than 260 individuals. It showed that a single dose of the Pfizer-BioNTech coronavirus vaccine for those who previously contracted Covid-19 can generate a response similar to those receiving the two doses of vaccine.

"We compared the responses of individuals with confirmed prior infection to those of individuals without prior evidence of infection," it added. "Post-vaccine symptoms were more prominent for those with prior infection after the first dose, but symptomology was similar between groups after the second dose," it stated.
