Nutrition status and COVID19 Vaccination - Can our height, weight, body mass index and nutritional status determine how many doses of corona vaccine we should take?

A recent study with 9171524 participants  published in The Lancet Diabetes & Endocrinology (DOI:https://doi.org/10.1016/S2213-8587(22)00158-9) uncovered that compared with unvaccinated subjects, the risk of hospitalization for COVID-19  was similarly decreased BMI ranges (underweight: OR 0·51 [95% CI 0·41–0·63]; healthy weight: 0·34 [0·32–0·36]; overweight: 0·32 [0·30–0·34]; and obesity: 0·32 [0·30–0·34]), with more protection among overweight and obese patients. Similarly, two doses of vaccine led to a greater reduction in the risk of mortality among obese and overweight patients (underweight: 0·60 [0·36–0·98]; healthy weight: 0·39 [0·33–0·47]; overweight: 0·30 [0·25–0·35]; and obesity: 0·26 [0·22–0·30]). The study also showed significant linear associations between BMI and COVID-19 hospitalization and death after the first dose, and J-shaped associations after the second dose of the COVID-19 vaccine. However, patients with normal BMI still had the lowest risk of mortality and hospitalization. Furthermore, the protection caused by the booster doses of the COVID-19 vaccine similarly increased across all ranges of BMI.
