Yellow fever vaccinations are required for visitors over the age of one year travelling from affected areas (as notified by the WHO).
While there are no other specific vaccinations required for visitors travelling to Barbados, it is advisable for you to be up to date on routine immunisations, such as for polio, tetanus-diphtheria, measles, mumps, rubella, and the seasonal influenza vaccine.
Your personal physician may recommend preventative measures against mosquito-bourne diseases and commonly recommended vaccinations for Hepatitis A (for all travellers), and Hepatitis B (for long-stay visitors).
The evolving situation with respect to the COVID-19 pandemic may require special health requirements for entry into Barbados at the time that UNCTAD 15 is held. While these cannot be anticipated with any certainty at this time, the host country will notify member states well in advance of the dates of the rescheduled Conference on any measures which may be put in place to safeguard the health and safety of both visiting delegates and the local population of Barbados.
