Hi
Thanks for choosing HCM for your query.
I appreciate your concern for your friend's health.

Typhoid is a bacterial infection caused by drinking contaminated water or food.
Provision of safe drinking water in most of the developing countries is a big challenge.
Ask your friend to drink safe drinking water preferably after boiling it and avoid eating improperly cooked vegetables and poultry.

There is a vaccine available which is useful in prevention of typhoid in highly endemic areas.
The injectable Vi capsular polysaccharide vaccine (ViCPS vaccine) is given intramuscularly in a single dose.
Protection is induced about 7 days after the injection.
The protective efficacy 1.5 years after vaccination is about 72%;
after 3 years it is about 50%.
To maintain protection, re vaccination is recommended every 3 years.

Hope your query is being answered.
A feedback is highly appreciated.

Greetings! Brother, I was bitten by dog on 14th January 2014 in the morning around 6. a.m. Around 6.45 a.m I went to clinic and they wiped it. Then around 10 a.m on the day I was given a tetanus injection and started taking antibiotic for a week. Evening around 5 p.m I was given a anti rabies vaccination. I was given anti rabies vaccination for 14 days consequatively around nipple and then after 10 days 1 injection then 10 days after 1 injection and after 10 days last injection. So total 17 injections around the nipple. That means, January - 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ Feb 6, 16, 26 dates I was given a anti rabies vaccination. On 16th Feb. I had a food poison due to the juice (awakadu) which I was taken outside. Again I was given anti biotic. I completed it. After food poison I feel in my mouth I am getting saliva. Doctor checked my blood they told I have a 108 sugar and 225 is a colostratral. Yet dog is alive and owner of the dog says it is in a good condition. Can you please tell me if possible the reasons of saleva I am getting it. I am also not feeling hungry. If time permits kindly reply brother. With respects, moses

I am going to Cambodia on November 3rd on a mission trip. On Sept 20, I began my series of required vaccinations. I received the Hep A and B vaccines that day. About 4 hours after getting the vaccines, I began having pain in my right shoulder, collarbone and down my right arm. I still have pain in these areas, sometimes mild and sometimes moderate to severe. In the last week I have developed pain in my right jaw, temple, ear and the right side of my neck. Is this the result of the vaccines. I m starting to get concerned.
