Healthcare workers with obesity found to produce only about half the antibodies healthy people do
The Pfizer/BioNTech vaccine may be less effective in people with obesity, data suggests.
Italian researchers have discovered that healthcare workers with obesity produced only about half the amount of antibodies in response to a second dose of the jab compared with healthy people. Although it is too soon to know what this means for the efficacy of the vaccine, it might imply that people with obesity need an additional booster dose to ensure they are adequately protected against coronavirus.
