Scientists have warned that the emerging coronavirus vaccine made by Pfizer may be less effective in obese people.
Researchers in Italy said that people who suffer from obesity might need a larger dose, or another additional dose, to protect themselves from the virus, according to what was published by the British newspaper “Daily Mirror.”
The researchers explain that compared to healthy people who suffer from severe overweight; Healthcare workers only generated half of the antibodies to ward off Covid-19 after receiving two doses of the Pfizer vaccine.
It is worth noting that antibodies are proteins that fight viruses that can stop the infection of the emerging virus, and they are a major part of the immune system, but there are other parts.
This is a double whammy for people who are very overweight because they are already considered to be at greater risk of serious illness or death if they contract the virus.
Scientists say this may be because obese people are more likely to have health conditions such as diabetes and high blood pressure, making them more vulnerable.
Obesity is defined as having a body mass index higher than 30, and experts said it is also known to hinder vaccines’ effectiveness. Previous research indicated that the flu vaccine could be half as effective in people who are severely overweight.
According to experts, carrying excess weight can lead to persistent inflammation of the immune system, impairs its functions. In healthy people, it causes inflammation only when the body is fighting an infection.
