Vaccination Strategies
The primary objective of vaccination strategies is to reduce disease incidence by achieving high immunity levels within targeted populations through sufficient vaccination coverage and vaccine effectiveness. The goal is to enhance individuals' immune systems to impede disease transmission.
Various vaccination strategies include:
- Pulse Vaccination Strategy: This approach aims to halt epidemic spread by repetitively vaccinating at-risk individuals within a defined age range until microbial transmission ceases. Employed during polio and measles outbreaks, it swiftly terminates dissemination and confines outbreaks.
- Ring Vaccination: In this method, all infected individuals in a specific outbreak area are vaccinated. It controls outbreaks by encircling each infected person with vaccinated individuals, curbing transmission.
- Cocooning (Immunization): Also known as the Cocoon Strategy, this approach safeguards vulnerable individuals by immunizing close contacts. Shielding newborns and susceptible individuals, it forms a protective "cocoon" when those most likely to transmit infections are immune.
