Yellow fever vaccine is a vaccine that protects against yellow fever. Yellow fever is a viral infection that occurs in Africa and South America. About 99% of people develop immunity within one month of vaccination and this appears to be lifelong. The vaccine can be used to control outbreaks of disease. It is given either by injection into a muscle or just under the skin.

Passengers travelling to and from YF endemic countries (countries where Yellow Fever disease is persisting) are required to be in possession of a “VALID YELLOW FEVER VACCINATION CERTIFICATE” issued by authorized and designated vaccination centers in India.

Passengers planning to travel to or passing through any of the Yellow Fever endemic country even while seated within the aircraft, are required to have the vaccination and in possession of VALID YELLOW FEVER CERTIFICATE in Original at all times, complete in all respects as per standards laid down by the WHO in its Regulations.

Since the Vaccine is developed and prepared in Chick Embryo, anyone having Allergy to Egg protein must not take the vaccination, as it is likely to lead to severe anaphylactic reaction, which could be fatal. Besides this other absolute contradictions are deficient immunity in individuals under medication for Thymus disease, Cancer, HIV/AIDS, on Corticosteroids for any reasons, suffering from any severe allergies.
