Yellow Fever

Yellow Fever Vaccine provides protection against Yellow Fever. This is a viral infection that spreads primarily through bites of female mosquitoes ( Aedes aegypti ) infected with the Yellow Fever virus (Flavivirus). The vaccine works by exposing your body to a small amount of the weakened form of the virus to which the body develops immunity.

Yellow Fever vaccine recommendations

Yellow fever vaccines are strongly recommended to people of the age group 9 months to 59 years of age if they are :
• Living in areas at high risk of Yellow Fever Virus (South America & Africa).
• Travelling to places with higher chances of Yellow Fever Infection.
• Going to countries with Yellow Fever Vaccine requirements.

One shot of the Yellow Fever Vaccine is enough for long-lasting protection against the Yellow Fever Virus. However, a booster dose is recommended every 10 years, for people at high risk.

Who should not get the Yellow Fever vaccine?

Yellow Fever Vaccine is not recommended to:

• Infants below 6 months of age.
• People who are allergic to vaccines or vaccine components.

Note: Infants between 6 to 8 months of age should only be vaccinated in case of a yellow fever epidemic or if travelling to a yellow fever–endemic zone, where there is a lesser possibility of protection against mosquito bites. A consultation with your doctor or healthcare provider is a must before vaccination.

Other groups that require proper doctor consultation before receiving the yellow fever vaccine, due to higher risks of adverse reactions include:

• Pregnant and breastfeeding women
• Adults over 60 years of age
• People with a weakened immune system due to long-term steroid therapy, HIV, organ transplant, and cancer patients.

If possible, travelling to a yellow fever zone should be avoided for these groups of people.
