About
100 percent of those in the country who have been vaccinated with two doses of
coronavirus vaccine have developed antibodies. The study found that 63 percent
of those who received the first dose of vaccine and 50 percent of those who did
not receive a single dose of the vaccine produced naturally occurring
antibodies.
This
information has come up in a survey conducted on 746 people in Chattogram for 5
months. The study was conducted by One Health Institute of Chattogram Veterinary
and Animal Sciences University (CVASU). Ten researchers took part in the study
led by CVASU’s Vice-Chancellor Professor Gautam Buddha Das.
Studies
have shown that the amount of antibodies (OMA) produced naturally in the body
of those who have not been vaccinated (average 53.71 DU / ml). On the other
hand, about three times more antibodies (159.08 DU / ml) on average were
produced by those who took a single dose of the vaccine.
CVASU’s
Vice-Chancellor Prof. Gautam Buddha Das said the study was conducted over the total
of 746 people including doctors, nurses, relatives of patients, outdoor and
indoor patients (coronavirus uninfected), cleaners and garment workers at
various public and private hospitals in Chattogram, who received the first dose,
second doses of vaccine or not being vaccinated yet, were studied.
This
study analyzes various issues related to seropositivity (presence of SARS-Cov-2
antibodies in the blood). The survey was conducted from March 2021 to September
2021. The presence and amount of antibodies in the study were determined by
enzyme-linked immunosorbent acid (ELISA).
The
study found that out of a total of 746 spontaneous participants, about 30
percent (223 people) took the first dose of the corona vaccine and about 31
percent (231 people) took both doses. And 39.14 percent (292 people) did not
get vaccinated.
The
researchers also found that the average amount of antibody titer (175.1 DU /
ml) present in the body in the first month after the first dose is reduced by
about 25 percent in the second month. But after the second dose of vaccine, the
amount (average) of antibodies varies with time.
Studies
have shown that those who took the second dose of the vaccine lost an average
of 21 percent of the antibody titer (324.42 DU / ml) within two months of
completing the second dose in the fourth month, but But in the sixth month, it
dropped to only 3.4 percent in the fourth month.
Gautam
Buddha Das, head of the research team, said that even six months after taking
the second dose of the vaccine, there are enough antibodies present in the body
to protect the coronavirus. The results of this study shed light on the need
and success of the ongoing vaccination program in the country to combat the Covid-19
pandemic.
A
significant goal of the ongoing study is to determine the percentage of
antibodies (OMA) produced against the SARS Cov-2 virus among study
participants, the researchers said.
The
research team consists of Professor Dr Sharmin Chowdhury (Head Researcher) of
One Health Institute, Dr MA Hasan Chowdhury (Head Researcher), Head Professor
of Medicine, Chattogram Medical College, Dr Jahan Ara (Assistant Researcher),
Dr Sirajul
Islam (Assistant Researcher), Dr Tareq Ul Quader (Assistant Researcher). Dr Anan
Das (Assistant Researcher), Dr Mohammad Saiful Islam (Assistant Researcher), Dr
Yasir Hasib (Assistant Researcher), Dr Tazrina Rahman (Assistant Researcher)
and Intern Dr Simanta Das (Assistant Researcher).
