Mexico Vaccinations


General Advice

It is vital that every participant visits their doctor or travel clinic at least 2 months prior to departure in order to get the latest advice on vaccinations and medications for the region. Some people are not able to have certain injections, so we cannot give blanket advice over which vaccinations you need. It is also worth checking the Travel Health Pro website or the Centres for Disease Control for up to date advice. This advice is based primarily on UK government guidance, and if local advice is preferred this should be sought separately.


Everybody must see a doctor or travel nurse to get official advice on which vaccinations are necessary.

Rabies: Your health professional may ask you whether you will be at an increased risk of rabies. It is not compulsory to get the rabies vaccinations as you will not be handling mammals and we have protocols in place to ensure that in the very unlikely event that you were bitten by a potential rabies vector, appropriate treatment could be given within a suitable timeframe. The only exception to this are those doing a dissertation on bats, who we require to be vaccinated.

Yellow Fever: The yellow fever vaccination is not currently advised for travel to the area that we are working in. However, if you are travelling through or from a yellow fever zone, then you must make sure that you have had the yellow fever vaccination and that you carry your proof of vaccination. Click here for the World Health Organisation’s advice on yellow fever vaccination requirements for international travellers to any country.

Covid 19: We recommend our participants are fully vaccinated against COVID, particularly because we work in remote locations where the local communities may not have been offered the vaccine and medical facilities may be more limited, but this is no longer mandatory to join our expeditions. Proof of vaccination may be required for entry to certain countries or for transiting during travel so please do check in advance.

Other Considerations

Malaria and Dengue

Malaria and Dengue are both present but the risk in the areas we work in extremely low and so it is unlikely that your health professional will recommend you take malaria prophylactics. There are no prophylactics available to protect against Dengue. The best form of protection against both diseases is to prevent mosquito bites as much as possible. You can do this by wearing long sleeved clothing, particularly in the mornings and evenings, and by having a good insect repellent (see kit list for repellent advice).

If you are diving as part of your expedition and are given Larium as a prophylaxis please ask for an alternative. You cannot dive on Larium and anyone taking it will not be allowed to dive on site.


Zika is also present. As with dengue there is no prophylaxis available and so the best way of reducing risk is to cover up to protect yourself against mosquito bite. Zika can be carried asymptomatically and passed on through sexual contact, and there is a small risk that it can cause serious problems during pregnancy. As such the current advice is to avoid unprotected sex for a period of 6 months following travel.

Sexual Health

HIV/Aids and Hepatitis B are present in some form in each country that Operation Wallacea operates in, but there is no reason why this should present a problem 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, diarrhoea and whilst taking antibiotics so please bring alternative methods of contraception, even if you are travelling with your partner.
