Many vaccine-preventable illnesses, including hepatitis A, carry a greater risk of complications in older people. Recommendations are the same as for adult travellers generally. However, response to
vaccinations may take longer in older individuals and the efficacy of some vaccines may be compromised due to the diminished immune response in older people (Gautret et al 2012). In addition older travellers should be made aware of the importance of additional avoidance measures, such as precautions about food, water and personal hygiene.
