a study by Oxford University, published in Lancet Diabetes and Endocrinology The vaccine’s efficacy may be slightly lower in people who are underweight compared to those with a high body mass index (BMI) and at a healthy weight. This study evaluated the risk of serious disease in vaccinated people compared to non-vaccinated people with an interval of at least 14 days after the second dose.
The study suggests that one of the reasons for the low efficacy of the Kovid-19 vaccines in people who are underweight may be body weakness or other conditions associated with low body weight. Researchers associated with the study also found that people who were underweight were also the least likely to be vaccinated, although people who were underweight who were vaccinated were 50% more likely to end up in the hospital or succumb to COVID-19. was reduced to For unrelated people of the same BMI.
The study also found that those with a healthy or high BMI and who were vaccinated were 70% less likely to be hospitalized than those without the same BMI. Those — those with a healthy or high BMI — were two-thirds less likely to die than their unconstrained counterparts even two weeks after the second dose. However, those with a very high BMI negated any benefit, with a higher likelihood of hospitalization than those with a healthy or moderately high BMI.
The study, which analyzed BMI data of 9,171,524 patients over the age of 18 who had not previously been tested positive for COVID-19 between December 8, 2020 and November 17, 2021, found that 17 A person with a BMI of A had a 50% increased risk of hospitalization compared to a person with a BMI of 23 – considered healthy – a person with a BMI of 44 was three times more likely to be hospitalized against a person with a healthy BMI There is risk.
According to study lead author Dr. Carmen Piernas from the Nuffield Department of Primary Care Health Sciences at Oxford, the research findings “highlight the need for targeted efforts to increase the vaccine among people with low BMI, where the uptake is currently low. High People with BMI.”
Experts are deeply concerned that the world is still not using one of its most effective weapons against COVID – properly ventilating public places – more than two years into the pandemic.
One big concern: “We need to reduce the level of contamination, which the vaccine alone cannot do,” Antoine Flehault, director of the Institute of Global Health at the University of Geneva, told AFP. “We need a new phase – improving indoor air quality.”
Why: Although it is generally accepted that COVID can be transmitted through both droplets and aerosols within two metres, there is no consensus on the importance of long-distance air transmission indoors.
study: A team of researchers from the UK Health Protection Agency and the University of Bristol reviewed 18 studies in several countries on airborne transmission.
Test Result: In research published this week, they found that people can infect each other when they are more than two meters apart.
Flahault called for massive funding to ventilate many public spaces, starting with schools, hospitals, public transportation, offices, bars and restaurants. more information Here
