The people who have got vaccinated were not included in the research.
According to the research report, it has been proved that the number of asymptomatic Covid carriers is higher and they are roaming around freely.
The research team said, “The people among whom natural antibodies were found somehow came in contact with the virus or got infected with it. But 60 per cent-70 per cent antibodies are needed in a human body for developing the much-desired herd immunity. So, there’s no alternative to vaccination.”
He also urged all to take vaccine soon to save their lives from the highly contagious virus.
Chairman of the JUST’s Microbiology Department and assistant director of the Genome Centre prof Mohammad Iqbal Kabir led the research team.
