Final answer:
Zostavax must be used within 60 minutes of being reconstituted with a diluent.
Step-by-step explanation:
Zostavax is a vaccine used to prevent shingles in adults. Once the vaccine is reconstituted with a diluent, it must be used within 60 minutes to maintain its effectiveness. After 60 minutes, the vaccine may not provide the intended protection.
This information is important because it ensures that the vaccine is properly administered and that individuals receive the full benefits and protection against shingles.
