Covid-19 recovered people showing faster antibody response to Covishield vaccine: Study

Pfizer’s COVID-19 Vaccine May Be Less Effective in Obese People, Study Says. Researchers in Italy have discovered that the Pfizer/BioNTech vaccine may be less effective in obese individuals. . Their study, which has not been peer reviewed, followed the antibody response caused by two doses of the Pfizer/BioNTech vaccine. In 248 healthcare workers, 99.5 percent were found to have developed an antibody response. . In people who were overweight and obese, that response was found to be blunted. In a separate study of healthcare workers in Brazil, COVID-19 reinfection was more common among people with a higher BMI. Excess body fat can cause metabolic changes such as inflammation and insulin resistance. This constant state of low-grade inflammation can weaken immune responses, which means it’s harder for the body to fight off infection. . Previous research has found that obesity, aka a BMI over 30, increases the risk of dying from COVID-19 by almost 50 percent. . It also increases the risk of being hospitalized with COVID-19 by 113 percent
