It's based on statistics. Just because you got through with no problems doesn't mean everyone who is obese will do.I’m classed as clinically obese and had covid at the start of January. I’m 30 and I don’t have any underlying health conditions and had no issues with breathing during the time I was unwell, it was just like a bad flu with loss of taste and smell.
I think there’s too much scaremongering going on but I hope I get the vaccine soon so I can feel more comfortable when I go out.
Age is the highest risk factor followed by obesity. It's people with a BMI of over 40 who are classed as vulnerable for vaccination.
