Read more about the single vaccinations below.
Diphtheria
Diphtheria is a serious throat infection, which infects from person-to-person through the air. The vaccination should be less than 10 years old otherwise a booster is needed.
Tuberculosis
The vaccine against tuberculosis, BCG, is recommended to people stationed in high-risk areas for more than 6 months, who have not been vaccinated previously. The vaccine contains live bacteria which produces a small wound, as well as scar after healing. The whole process takes 4 to 8 weeks.
Hepatitis A (infectious hepatitis)
Infectious hepatitis infects through food and water. Vaccination consists of two injections about 12 months apart, which protects for up to 20 years. The first vaccination protects for 12 months. Gamma globulin consists of purified antibodies from people who have had hepatitis A, and protects for up to 5 months. The vaccination is preferred. The hepatitis A vaccine can be combined with the vaccine against hepatitis B.
Hepatitis B
Hepatitis B infects through blood, sexual ac-tivities and, in small children, through saliva. The vaccination consists of 2 vaccinations about 4 weeks apart and a third 6 months later. The protection is for at least 10 years. The hepatitis B vaccine can be combined with the vaccine against hepatitis A.
Tetanus
Tetanus is a complication to wounds contaminated by soil. If there has been a vaccination within the past 10 years it is not necessary to give a booster in case of wounds and accidents. Tetanus is usually given in combination with diphtheria. If you are previously vaccinated, the vaccine can be given right up to departure.
Typhoid
Typhoid is the most serious of the Salmonella infections. There are two types of vaccine: 1. Vaccine for injection. 1 vaccination protect up to 3 years. 2. A live vaccine in capsules, which is swallowed. Three capsules are taken 2 days apart and provide protection for a year.
Malaria
Risk of malaria in this area is small, and pre-vention by malaria tablets is not recommended. Protection against mosquito bites for instance by using an impregnated bed net at night will reduce the risk further.
Yellow fever - transit
Certain countries require a valid yellow fever vaccination certificate if you arrives (even in transit) from a country where yellow fever is present. If you arrive from a country without yellow fever, there is no requirement for a yellow fever vaccination.
Japanese encephalitis
Japanese encephalitis is caused by a virus spread by mosquitoes. Vaccination consists of 3 injections with 2 weeks apart and protects for up to 2 years. Vaccination should start 4 weeks before departure.
