No threat of contracting Covid-19 because of vaccination: DGHS
The Directorate Standard of Health Offerings in a statement Monday said there is no threat of testing Covid-19 positive consequently of taking the Covid-19 vaccine shot.
It employs some public statistics revealed they tested great despite taking their initially dose of the vaccine.
Disaster Management and Relief Secretary Md Mohsin tested positive for Covid-19 twelve days after getting his primary dose of the Oxford-AstraZeneca vaccine that's being rolled out in Bangladesh.
Bangladesh countrywide hockey team coach Mahbub Harun tested positive with 65% infection on lungs within weekly of taking his 1st dose of the vaccine.
Well known film director Kazi Hayat and his wife also analyzed positive in a matter of six days of obtaining their 1st dose of the vaccine.
These prominent cases combined with current upswing in infections along with deaths to fuel issues more than the efficacy of the vaccine - to the idea that some commenced to link testing confident to having taken the vaccine.
Why you might still test positive
While some vaccines stop persons from getting infected, rendering what's called sterilising immunity, others are aimed at protecting against symptomatic disease - you might still get infected, but the immune response triggered by the vaccine will battle off extreme disease. The Covid-19 vaccines fall in the latter category.
The DGHS statement rested on the fact that no-one in Bangladesh has yet received the recommended two doses of the vaccine in the first place.
“One has to wait a minimum of two weeks after taking the second shot to find the optimum immunity from the Covishield vaccine used in the Covid-19 vaccination drive," it said.
The Oxford-AstraZeneca vaccine has been branded as Covishield by its accredited Indian manufacturer the Serum Institute of India (SII).
"The risk to be infected with Covid-19 remains the same if the health guidelines aren't maintained properly in this waiting period (between your first of all and second doses)."
Difference between immune response and whole protection
"It is true that the immune response begins after acquiring the jab but protection comes only one time a good person completes the recommended dosage," Dr Be-Nazir Ahmed, ex - director (disease control) of the DGHS, told UNB found on Monday evening.
He as well said, "Vaccination means you have to complete acquiring all the doses of a vaccine to achieve the complete protection."
"Due to the AstraZenecca Covid-19 vaccine is a good two-shot vaccine, a single cannot claim to get infected by Covid-19 despite vaccination before acquiring both shots," he added.
To measure the efficacy of a vaccine, completing all of the dosages is a precondition, Dr Be-Nazir said.
"The virus may enter one's body before taking the photos and become in incubation period, without showing the symptoms. During this period if one will take the vaccine and then tests positive, that would actually be because of a prior exposure. As the virus had been within the body and the immune response triggered by the shot hadn’t started yet, the person would wrap up with Covid-19,” said the previous director of DGHS.
It can be mentioned that Covid-19 may be the brand given to the disease caused by infection with the novel coronavirus.
Dr Be-Nazir remarked that it is being advised across the world to preserve maintaining the non-pharmaceutical well being guidelines together with vaccination drives nowadays underway in a number of countries.
"The AstraZeneca Covid-19 vaccine was claimed with an efficacy of 60%-70%, meaning caution has to be maintained possibly after taking both shots,” he reminded.
"However, vaccination is important and logical since it lowers the chance of severe disease or loss of life from COVID-19. To protect your life you need to take the vaccine," he concluded.
