Describe two examples of when vaccination is used apart from the schedule?

Catch-up Vaccination: Individuals can fall behind vaccination due to various reasons like illness, lack of access to healthcare, or missed appointments. To address this, catch-up vaccination is recommended once they recover or gain access to care. It involves an accelerated schedule to help them obtain all the necessary doses as quickly and safely as possible.

Pre-travel Vaccination: International travel may expose individuals to infectious diseases not common in their home regions. Therefore, health organizations recommend pre-travel vaccinations to protect travelers from diseases like yellow fever, malaria, typhoid, and Japanese encephalitis. Vaccination requirements may vary based on specific travel destinations.
