Your flights and accommodation are booked, your passport is in date and your flip-flops are ready to be packed for your holiday abroad, but have you covered all the travel requirements? If you're panning on jetting off to a tropical destination, then chances are you may need to be vaccinated before you go to prevent contracting any diseases.

Holidays abroad offer a fantastic chance to experience a new culture in a fascinating new country. But immersing yourself in a new way of life can leave you susceptible to illnesses you wouldn't normally encounter at home.

Don't be put off by this though; once you're vaccinated you can make the most of a holiday abroad without worrying about returning feeling unwell rather than relaxed and refreshed.

British childhood vaccinations are designed to protect against diseases found within the UK, so they not cover diseases that are common further afield. After choosing to go on holiday in tropical destinations such as Africa, Asia and South America, you need to make sure you're correctly protected.

African resorts such as Kenya, Gambia and Tanzania all recommend visitors to have had boosters for tetanus, hepatitis A, typhoid and diphtheria, but the range of vaccinations required varies for each individual. If you choose to go to Africa, you'll also have to complete a course of anti-malaria drugs.

Similarly, if you choose to travel to an Asian resort like Thailand or a South American country, such as Brazil, then boosters for diphtheria, tetanus and hepatitis A are usually advised. Always check the rules for the specific country and resort you are visiting as they can differ from year to year. Your local health services can also offer advice on the appropriate health precautions for your travels.

Some vaccinations can cause side effects for a few days after being administered, so take this into consideration when planning your vaccination appointments. Also bear in mind that vaccines take time to go into effect, so make sure you're properly covered in time for your trip. In some cases you may need to have been vaccinated for a few months before you leave for your tropical getaway, so don't run the risk of leaving it too late.

Before you jet off on any holidays abroad, consider other health and safety precautions in addition to vaccines, such as mosquito nets and sunscreen. You may also want to bring a travel first aid kit with you, particularly if you're planning to explore more remote destinations.

Finally, many countries will not allow you to enter unless you have proof that you are vaccinated against certain diseases. When you go for your vaccinations you'll be issued a certificate to prove you a successfully protected for your holiday; don't forget to bring this with you on your journey.
