The anaesthesiologist says im severely allergic to morphine. my dentist says im moderately allergic to prilocaine, benzocaine and forte ( with epinephrine). will having these allergies present a problem in taking astrazeneca vaccine?

None of these ingredients are in or related to the Covid vaccine. However, anyone who has had an allergic reaction to a medication is generally observed for a longer period of time after the vaccine to be sure.

Yes, you have had demonstrated allergic reactions to several medications, but this does not contra-indicate vaccination. Get the JAB, and stay under direct observation for about 45-60 minutes, just to be safe. Do not really foresee a problem, but cover the bases.

The good news is that there is no correlation between the Astra-Zeneca vaccine and the medications you mentioned. As you have had untoward reactions to other medications, make sure you remain under observation for an hour after the shot. considering the alternative, not being vaccinated and the risk of serious illness/death, please get vaccinated.
