'COVID-19 vaccine may not work as well on obese people'

Obesity increases risk of death from COVID-19 by almost 50%, study finds

A new study has shown that coronavirus vaccines may not work as effectively for obese people, who are also 48% more likely to die from COVID-19, local media reported on Wednesday.

The World Bank commissioned the US’ University of North Carolina (UNC) at Chapel Hill to analyze global data from countries including the US, UK, China, France, and Italy.

The study showed that obese people were 113% more likely to be hospitalized due to COVID-19, 74% more likely to enter intensive care, and 48% more likely to die.

“It is a 50% increase essentially. That’s a pretty high scary number. All of it is actually – much higher than I ever expected,” UNC’s Professor Barry Popkin, who led the study, told British newspaper The Guardian.

“We know a COVID vaccine will have a positive effect on obese people, but we suspect from all our knowledge from tests on the SARS vaccine and the flu vaccine, it will have a diminished benefit compared to the others.”

Obesity increases the likelihood of heart disease, Type 2 diabetes, insulin resistance, and inflammation, all of which increase the risks from coronavirus.

Co-author Professor Melinda Beck was quoted by The Guardian as saying: “All of these factors can influence immune cell metabolism, which determines how bodies respond to pathogens, like the Sars-CoV-2 coronavirus.

“Individuals with obesity are also more likely to experience physical ailments that make fighting this disease harder, such as sleep apnea, which increases pulmonary hypertension, or a body mass index that increases difficulties in a hospital setting with intubation.”

Over 40% of Americans and 27% of adults in England are obese, according to government data.

In the UK, Prime Minister Boris Johnson launched a national anti-obesity drive earlier this year.
