Travellers should be up to date with routinely recommended vaccinations according to the routine UK immunisation programme.
Vaccination could be considered for travellers whose activities put them at increased risk, including those visiting friends and relatives, and frequent or long-stay travellers to areas where sanitation and food hygiene are likely to be poor.
Vaccination recommended for travellers whose activities put them at increased risk, including those who are staying with or visiting the local population, frequent and/or long-stay travellers to areas where sanitation and food hygiene are likely to be poor, adventure travellers visiting rural areas and staying in basic accommodation, those with existing medical conditions such as liver disease or haemophilia, men who have sex with men, injecting drug users, and those going to areas of hepatitis A outbreaks who have limited access to safe water and medical care.
Vaccination recommended for travellers whose activities or medical history put them at increased risk, including those who may have unprotected sex, those who may be exposed to contaminated needles (eg, through injecting drug use or receiving medical or dental care), those who may be exposed to blood or body fluids through their work (eg, health workers), long-stay travellers, those who are participating in contact sports and families adopting children from this country.
Vaccination recommended for travellers whose activities put them at increased risk, including those at risk due to their work (eg, health workers or those working with animals), those travelling to areas where access to post-exposure treatment and medical care is limited, those planning higher risk activities such as running or cycling, and long-stay travellers.
Vaccination is recommended for travellers aged 9 months and older travelling to Corrientes and Misiones Provinces including the Iguaçu Falls.
Vaccination is generally not recommended for travel to areas with low potential for exposure to yellow fever (Formosa Province and designated areas of Chaco, Jujuy and Salta Provinces) but could be considered for a small subset of travellers who are at increased risk because of:
- Prolonged travel
- Heavy exposure to mosquitoes
- Inability to avoid mosquito bites
Travellers should have completed a primary vaccination course according to the UK schedule. If travelling to a country where medical facilities may be limited, a booster dose of a tetanus-containing vaccine is recommended if the last dose was more than ten years ago even if five doses of vaccine have been given previously.
