Hepatitis A. (Gamma Globulin). Passive immunization for hepatitis or liver disease — only necessary in high risk tropical areas. Repeat injections are necessary every four months in highly infectious areas.

Hepatitis B. Immunization against this usually sexually transmitted or blood transmitted infection is necessary for those exposed to it by the nature of their work, for example, medical personnel; laboratory staff.

Typhoid and cholera are diseases caused by germs invading the bowel. Both are serious. They occur mainly in countries where hygiene and sanitation are poor. Travellers to these countries should have immunization before visiting. Protection by having injections to boost the antibodies against these diseases is not altogether complete. Should the germs enter the bowel in overwhelming force the disease may develop, but would be mild and unlikely to be severe or fatal. Immunization against typhoid gives protection for about three years; that of cholera only six months.

Rabies. Immunization and regular boosters are needed when visiting or living in areas where animals are infected with this disease. It is transmissible usually by the bite of an infected animal.

Yellow Fever. A disease transmitted by mosquitoes in certain tropical areas. Immunization is given at special government health centres and usually boosters are required every ten years to maintain immunity.

Smallpox. The world-wide eradication of this disease has made vaccination against it both unavailable and unnecessary.

Advice may be obtained from travel agents, embassies, or your medical practitioner regarding special injections or malarial tables necessary in various parts of the world. Boosters of Tetanus and Polio may also be required. It is important to start the injections several weeks in advance of the date of departure.

The body has a marvellous defense organization and its efficiency can be increased, not only by general healthful living, but by taking advantage of modern medical science.

1. Be prepared

A. To undertake an active immunization Program so that antibodies are built up ready for the invading germs, rather than waiting several weeks for a slow natural response.

B. Use prescribed antibiotics and other antibacterial medicines which may be life saving in severe infections.

2. Be kind to your body cells and their life supporting tissue fluid.
