I'm really concerned about my dad. He's 63 and he's been dealing with asthma for a long time. He's currently using a Formoterol Fumarate and Budesonide Inhaler at 400 mg and taking Bilagra M tablets. I'm worried about whether it's safe for him to get the Covishield vaccine with these meds. Can you advise on whether it's okay for him to proceed with the vaccination?
