Vaccinations for Tonga
Tetanus is contracted through contaminated cuts, bites and breaks in the skin. The vaccination provides cover for approximately 10 years in the majority of patients. It is frequently combined with cover against other diseases such as Poliomyelitis, Diphtheria and/or Pertussis.
Hepatitis A is a common disease in many of the hotter regions of the world and usually contracted through contaminated food and water. Cover against Hepatitis A can be given alone or combined with protection against Typhoid or Hepatitis B. Once completed, the Hepatitis A vaccination (given on two occasions 6 to 12 months apart) provides cover for approximately 25 years in the majority of patients.
Typhoid is a bacterial disease contracted through contaminated food and water. This vaccine can be combined with cover against Hepatitis A. Once completed, the Typhoid vaccination given on one occasion provides cover for between 2 to 3 years in the majority of patients
Hepatitis B is a viral disease which is usually transmitted in a very similar fashion to HIV/AIDS through contact with infected body fluids (eg blood exposure and sexually). This vaccine can be combined with cover against Hepatitis A. The standard schedule for Hepatitis B is to administer the vaccine on days 0, 28 and 180. A more rapid schedule can be used in cases where cover is needed more urgently and this is administered on days 0, 7, 21 to 28 and also 365. Following either course (and not before completion) a blood test can be taken to confirm sufficient antibody protection. Where the correct level of antibodies are showing (>100iu) the vaccination is recognised to provide cover for life.
