Most people tolerate the vaccine well, with only mild side effects such as soreness at the injection site, headache, muscle aches, or a mild fever.
Rarely, more serious reactions can occur. These include severe allergic reactions, problems affecting the nervous system, or multiple organ failure. Such reactions are very uncommon (estimated at 1 in 50,000 to 1 in 250,000 doses), but the risk is slgihty higher in people over 60 or those with weakened immune systems.
Whilst this can sound worrying, in most cases the protection against yellow fever far outweighs the very small risk of a serious reaction, particularly when travelling to areas where the disease is common.
Our travel nurse will assess your individual risk before vaccination and discuss any concerns with you.
