The choice of delivery method depends on several factors:
- Type of Vaccine: Some vaccines are more effective when delivered via specific routes. For instance, live attenuated vaccines often work best when administered orally or nasally as they mimic natural infection routes. - Target Population: Age, health status, and pre-existing conditions of the target population can influence the delivery method. For example, oral vaccines are often preferred for young children. - Logistical Considerations: Storage, transportation, and ease of administration also play a role. Oral vaccines, which do not require needles, can simplify mass vaccination efforts.
