Covid 19 vaccine jab is less effective on fat people; who are at a higher risk of hospitalization or death from Covid-19 complications.
According to a study published by The Lancet Diabetes and Endocrinology journal, Covid 19 vaccine jab is less effective, on people with a higher Body Mass Index or overweight.
The study Lancet study was published on June 30, 2022.
The research says that low vaccine effectiveness to obese people is due to biomechanical and systemic factors that increase the risk of adverse outcomes.
It argues that those with obesity are more likely to experience more serious clinical consequences as a result of Covid-19 infection.
Diabetes, hypertension, and other respiratory issues are known risk factors for severe Covid-19, and obesity is also linked to these conditions.
A higher body mass index is a known risk factor for non-communicable diseases, and when the conditions set in, they place one at a greater risk of dying, according to Dr. Willis Akhwale, the chair of the Vaccine Task Force.
“The fact that Covid-19 vaccines are found to be less effective on obese people, it doesn’t mean they are not effective at all. These are people who are at high risk so they need to take the vaccine, even as we look at other interventions and improvement on more effective vaccines and also treatment,” Dr. Akhwale said.
Dr. Andrew Mulwa, the Director of Medical Services, Preventive and Promotive Health at the Ministry of Health said that obesity exposes one to cardiovascular, metabolic syndrome, cancer, and many other diseases.
“A person with obesity has a higher risk of severe Covid-19 illness even when vaccinated. A normal person will get protection from severe Covid-19 more than an obese person,” said Mulwa.
The Lancet Diabetes and Endocrinology journal used a large representative population-based cohort of 9,171,524 individuals from England to investigate severe Covid-19 outcomes after vaccination and its associations with BMI
In the vaccinated cohort, there were increased risks of severe Covid-19 outcomes for underweight people or obese compared with the vaccinated population with a healthy weight.
