Discussion post: Life Span Nursing Consideration

Describe what life span considerations you might use in applying the nursing process to infants, school-age children, younger adults, and older adults in relation to immunizations and wellness.

P.S, please follow the instructions as it asks and answer the question.

I only need half-page and two references from  Potter, P, A., Perry book and Scholar article that are less than five years of publication.
Thank you
