A new study has claimed that a single dose of Russia's Sputnik V vaccine is enough to generate a stronger antibody against coronavirus. The study found that 94% participant who had received first dose of Sputnik vaccine dose, developed virus-specific immunoglobulin G (IgG) antibodies within 3 weeks. Three weeks after the second dose, all volunteers with no prior infection generated IgG antibodies. A second dose did not increase the production of neutralising antibodies in previously infected volunteers. The high antibody levels after a single dose in naive participants suggest a benefit of delaying second dose administration to increase the number of people vaccinated, researchers said.
