- COVID-19 symptoms may be mild or make some people need a machine to breathe
- The risk of developing dangerous symptoms may be increased in male and obese people
- Therefore, body mass index and gender should be used as an indicator for vaccine effectiveness
What Makes Obese People so Vulnerable to COVID-19?
There are always going to be little differences in the way our body’s function and those changes can ultimately affect the ways we respond to everything. So, incorporating those differences such as metabolic diseases and pre-existing conditions can tell about how vaccines and therapeutics might be more or less effective in these people.![twitter](https://images.medindia.net/icons/news/social/twitter.png)

But these disparities were more pronounced in the female mice than in the males. In addition, female mice in the obesity group experienced high viral burdens and the most inflammation in their lungs.
Who Is at More Risk of Severe COVID-19 Infection?
Clinically, a lot of data shows that men are more predisposed to severe COVID-19 than women. While they can’t translate our findings from female mice directly to female humans, they do indicate an area for future study. They’re also relevant to the development of new vaccines and treatments for COVID-19, as well as other respiratory diseases.These mice are a new preclinical model we developed to be used as another tool to measure the protection of vaccines and other therapeutics the Vaccine Development Center has in development.
What we see with SARS-CoV-2 in a host with metabolic disease here is potentially relevant to respiratory pathogens and diseases. Pre-existing conditions and comorbidities are going to be really important to consider moving forward.
