Single Dose Of Sputnik V COVID-19 Vaccine Triggers Strong Antibody Response: Study

Sputnik V COVID-19 Vaccine: The new study, published on Tuesday in the journal Cell Reports Medicine, examined whether a single dose would achieve greater public health benefit than two doses by allowing protection of a larger population more quickly.

A single dose of the Sputnik V vaccine may be enough to elicit strong antibody response against SARS-CoV-2, the virus that causes COVID-19, in already infected people, according to a study. Previous studies have found that two doses of Sputnik V, a vector vaccine produced using a combination of two adenoviruses, results in 92 per cent efficacy against COVID-19 infection. Adenoviruses are common viruses that cause a range of illness with cold-like symptoms such as fever and sore throat. The new study, published on Tuesday in the journal Cell Reports Medicine, examined whether a single dose would achieve greater public health benefit than two doses by allowing protection of a larger population more quickly.
