In Odisha, about 20 percent of the people who have taken both the doses of the vaccine being applied to protect against the corona virus have not been able to make antibodies. These people may need a booster dose. The Bhubaneswar-based Institute of Life Sciences (ILS) has reported that 20 percent of people have not made antibodies against SARS-CoV2.
‘Vaccine effectiveness only 70 to 80 percent’
Dr. Ajay Parida said that the effectiveness of Covishield and Covaccine vaccines is only 70 to 80 percent. Not being able to make antibodies despite taking two doses of the anti-Covid-19 vaccine may be due to individual differences in the genetic sequence. “This fact was revealed through antibody genome sequencing study,” he said. Dr. Parida said that apart from children and adolescents in the age group of 0 to 18 years, these 20 percent of adults who have received both doses of the vaccine are also vulnerable to the infection of Kovid-19. They need to be extra careful during a possible third wave of the pandemic. ILS, Bhubaneswar, is part of the Indian SARS-CoV2 Genome Consortium, a network of 28 laboratories spread across the country.
