It states patient on immunosuppressant treatment for cancer within last 3 months at greater risk. "Surprisingly, people with cancer who had not recently been treated were not at heightened risk of serious outcomes from COVID-19. "

So what LK and Eric is close to the mark? It depends on other factors!

Does having a stoma make one immunio compromised?

I'm not aware of any studies or stats which indicate that having a stoma makes someone immunocompromised. 

But as @squeakyandliza suggested, the reason we have our stoma might, especially with certain medications. 

If your questioning this because of the Covid19  booster shot then all the more reason to ask about it.  I'm not sure where you reside, but Canada has just opened the Booster up to everyone.  The Booster is given 6 months after your second shot. 

I hope this is helpful to you. 

Why is absorb changed to the second b being a p, when writing absorption?
