Most people doesn't have any allergic reaction to it except for redness and swelling at the injection site as early mentioned and this is considered irrelevant when compared to effect of vaccine when contaminated by germ which could cause serious illness or death.
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:

Aerial stems are thin stems that can not stand erect.
