COVID-19 vaccine protects people of all body weights from hospitalization and death, shows study of 9 million adults thelancet
. Previous work has shown that people with obesity are less likely to take seasonal flu vaccines and have modestly reduced benefits from flu vaccinations, although the reasons for this are not well understood.
People were grouped based on their BMI according to four World Health Organization definitions of 18.5-24.9kg/mfor healthy weight; below 18.5 for underweight; 25-29.9 for overweight; and 30 and over as obesity with levels adjusted for Asian people to reflect the higher health risks at lower BMI levels in this group. Characteristics such as age, sex, smoking status, and social deprivation were also accounted for in the analyses.
In comparison, people in the healthy and high BMI groups who were vaccinated were around 70% less likely to be hospitalized than unvaccinated people. People with a healthy or a higher BMI were also around two-thirds less likely to die than their unvaccinated counterparts two weeks after a second dose.
