Can everyone get allergy shots?

No. If you have severe asthma or heart problems, allergy shots may not be good for you. You shouldn't get allergy shots if you take a beta blocker for heart problems. Children younger than 5 years of age also shouldn't get allergy shots.

Allergy shots shouldn't be started when a woman is pregnant. But if a woman has been taking allergy shots for some time and becomes pregnant, she should talk to her doctor. She may be able to continue taking her allergy shots.
