- In general, the flu vaccine works best among healthy adults and children older than 2 years of age. Reduced benefits of flu vaccine are often found in studies of young children (e.g., those younger than 2 years of age) and older adults (e.g., adults 65 years of age and older). Other studies have shown that vaccination can reduce the risk of flu-related hospitalizations in older adults. 2  A study that looked at flu vaccine effectiveness over the course of three flu seasons estimated that flu vaccination lowered the risk of hospitalizations by 61% in people 50 years of age and older.
