Operation Wallacea are not able to give official advice on inoculations. Some people are not able to have certain jabs, so blanket generalisations cannot be made. You must consult your GP, travel clinic or doctor for personal advice.
It is also worth checking the NaTHNaC web site for up to date advice. The NaTHNaC page for Guyana can be found here. The NHS also offers advice on their fit for travel website (found here for Guyana) although this maintains the assumption that you are up to date with inoculations as recommended for life in Britain.

To allow sufficient time for all the necessary immunisations it is recommended that you consult your Doctor or travel clinic three months prior to departure.
We suggest that you are up-to-date with the following inoculations though:
Yellow Fever – There is yellow fever present in Guyana so your medical professional should recommend vaccination. You will also require a yellow fever vaccination certificate to enter the country if travelling from a country with a risk of of yellow fever transmission. The current NaTHNaC list can be found here. The US, UK and Canada are not classed as having a risk of yellow fever transmission.
Rabies – You may have the opportunity to handle bats during surveys, however, you will only be able to do this if you have had the rabies immunisation. The general advice for Guyana and most countries in South America is to have the rabies course of injections as a precaution anyway.
Malaria – Malaria is present in Guyana so it is recommended you take prophylactics. Current NHS and NaTHNaC guidelines state that as Chloroquine resistance is widespread, they recommended chemoprophylaxis is mefloquine, doxycycline or atovaquone/proguanil (Malarone). However, advice changes from time to time so again, always check with your doctor for current advice. Most malarial prophylactics require you start taking them before travel. No drug offers complete protection from contracting malaria. The only sure way of preventing diseases transmitted through insect bites (particularly mosquitoes and ticks) is to prevent being bitten. Use precautions including insect repellent; cover exposed skin, use of mosquito nets etc.
HIV/Aids and Hepatitis B are present in some form in each country that Operation Wallacea operates in, but there is absolutely no reason why this should present a problem for anybody on an Opwall expedition providing you always act responsibly and practice safe sex.
There is a Hepatitis B vaccine available, as with all other vaccines follow the advice given by your medical professional regarding receiving it.
The effectiveness of the contraceptive pill is compromised in the instance of sickness, diarrhea and whilst taking antibiotics so please bring alternative methods of contraception, even if you are travelling with your partner.
