I cannot say about Malaria but last year we took a cruise around South America and were assured by P & O that we needed Yellow Fever vaccinations. Our local medical centre assured us we did not.
In the end we had them as P & O wer so insistant and we did not want any problems but were never asked to produce the certificate at any time on the 28 day cruise. We embarked at Rio de Janeiro and flew home from Lima, Peru.
I am not a doctor nor someone who practices with vaccinations so do not take what I say as gospel but....having looked at the itinerary I would say that the majority of passengers on that cruise will not have taken Yellow fever or Malaria precautions. There is a small risk but whilst cruising that risk is just that. The worst area you will encounter is the area around the coast of South America and Trinidad. If you intend to do any adventuring into the steamy flora or go ashore after sunset then it is always advisable to wear a mosquito repellent and clothing to cover extremities. If you want to be absolutely sure then take advice from experts, not people like me. I am just saying what the majority of passengers will be doing about that situation. I feel certain that I will get a broadside from one or two I could mention. Regards..... Neil.
I work in general practice and precautions change from week to week on the Travel Vaccine website which general practices use. I would go with your general practice and have both these, the hassle of having Yellow Fever vaccine, it lasts 10 years, and taking malaria tablets is definitely worth putting up with compared to the unthinkable.
Hello all....just to let you all no. i have made alot of calls to the doctors surgery and after having the yellow fever jab at £55 i was rang and told i didnt need it...nor did i need the malaria tablets either...due to not being on any island for a lenght of time and by the time the mossies come out we are back on the boat and away....and yes we made are complaints and got our money back for the yellow fever jab that we didnt need .
