Why COVID-19 Vaccine May Not Work In Nearly Half Of Americans
Obesity has been a national epidemic in the United States for decades. But the coronavirus may have exacerbated its health risks. Some experts speculate that any COVID-19 vaccine that emerges may not work in obese people. Writes about it Money Talks News.
Raza Sheikh, an assistant professor of nutrition at the University of North Carolina at Chapel Hill, made a blunt statement about the potential vaccine: “Will it work for obesity? Our forecast is no.”
Experts have known for a long time that vaccines used to protect against influenza, hepatitis B, tetanus, and rabies are not as effective for obese people as they are for those with normal weight.
Obesity contributes to the development of cardiovascular disease and even cancer. Now, research in a new science known as immunometabolism shows that obesity interferes with the body's immune response.
“A healthy immune system turns inflammation on and off as needed, calling up white blood cells and sending out proteins to fight infection. Vaccines exploit this inflammatory response. But blood tests show that obese people and people with associated metabolic risk factors, such as high blood pressure and elevated blood sugar, live in a chronic state of mild inflammation, experts say.

If the coronavirus vaccine proves ineffective for obese people, millions of Americans will be at risk. According to the Centers for Disease Control and Prevention (CDC), obesity rates among American adults rose to 42,4% in 2018. In 2000 this figure was 30,5%.
The CDC defines "obesity" as well as "severe obesity" based on body mass index. BMI is the correlation between a person's body weight and height.
The CDC classifies adults as obese if their BMI is 30 or more, and severely obese if their BMI is 40 or more.
