The yellow card is a certificate of vaccination to show that travellers have been immunised against yellow fever. Yellow fever is a mosquito-borne viral disease present in Africa and South America. The infection can range from mild to severe. Vaccination is the best protection against this virus.
The yellow fever vaccine provides protection against the virus for travellers and those living in areas where the disease is present. The vaccine is only available as an injection.
International travellers, including those transiting through high-risk countries, are required to compulsorily obtain the e-Yellow Card before travel, with vaccination usually recommended at least 10 days prior to departure.
