It is important to go to your doctor several months prior to your trip as some vaccinations take a few months for the series to be completed or several weeks before immunity is developed. It is important to know that a typical doctor's office will not have some travel vaccinations in stock, your doctor may need to order them or he may send you to a county health department where you can receive them. To find out what vaccinations are required as well as those that are recommended, it is best to refer to either the
World Health Organisation (WHO) or the
Centres for Disease Control and Prevention (CDC). It is a good idea to make a copy of the vaccination recommendations from the WHO and/or CDC and bring it along with you to your doctor's visit, or you may even wish to let them know what vaccination(s) you will require prior to your appointment so that they may order it and have it available for you at the time of your visit.
If you will be visiting an area where malaria is present you should discuss this with your doctor as well as any other health concerns that you or your doctor may have. It is important to know that most anti malaria medication needs to be commenced a few weeks prior to entering a malaria area for full protection, your doctor will let you know the requirements of the drug you should take, as the various antimalarial drugs work differently.
