Malaria is considered high risk in Nigeria, and antimalarial tablets are usually recommended. The right option depends on your age, medical history, pregnancy status, other medicines and how long you will be away. Mosquito avoidance still matters, especially between dusk and dawn, because tablets lower risk but do not make you untouchable. Yellow fever is another major Nigeria-specific issue. TravelHealthPro guidance states that yellow fever vaccination is recommended for travellers aged nine months and over, unless there is a medical reason not to have it. Certificate requirements can also apply when entering or leaving Nigeria, so your paperwork needs checking before departure. The vaccine is not suitable for everyone, particularly some older travellers or people with immune system problems, so proper assessment matters. Hepatitis A is commonly recommended because it spreads through contaminated food and water. Typhoid is also usually relevant, especially for longer stays, visits to friends and relatives, children and travel where food hygiene may be variable. Tetanus, polio and MMR should be up to date. Some travellers should discuss hepatitis B, rabies, meningococcal ACWY, cholera, TB risk and polio documentation. Nigeria sits within the extended meningitis belt, rabies is reported in domestic animals, and polio certificate rules may matter for stays of four weeks or more. Dengue, chikungunya and Zika are mosquito-borne risks too, with daytime biting mosquitoes involved. Avoid swimming or wading in untreated freshwater because schistosomiasis is present.
