 1 What is typhoid?
Typhoid (typhoid fever) is a serious disease. It is caused
by bacteria called Salmonella Typhi.
Typhoid causes a high fever, fatigue, weakness, stomach
pains, headache, loss of appetite, and sometimes a rash.
If it is not treated, it can kill up to 30% of people who
get it.
Some people who get typhoid become “carriers,” who
can spread the disease to others.
Generally, people get typhoid from contaminated food or
water. Typhoid is rare in the U.S., and most U.S. citizens
who get the disease get it while traveling. Typhoid
strikes about 21 million people a year around the world
and kills about 200,000.
 2 Typhoid vaccines
Typhoid vaccine can prevent typhoid.
There are two vaccines to prevent typhoid. One is an
inactivated (killed) vaccine gotten as a shot.
The other is a live, attenuated (weakened) vaccine which
is taken orally (by mouth).
 3 Who should get typhoid
vaccine and when?
Routine typhoid vaccination is not recommended in the
United States, but typhoid vaccine is recommended for:
• Travelers to parts of the world where typhoid is
common. (NOTE: typhoid vaccine is not 100%
effective and is not a substitute for being careful about
what you eat or drink).
• People in close contact with a typhoid carrier.
• Laboratory workers who work with Salmonella Typhi
bacteria.
Inactivated typhoid vaccine (shot)
• One dose provides protection. It should be given at
least 2 weeks before travel to allow the vaccine time to
work.
• A booster dose is needed every 2 years for people who
remain at risk.
Live typhoid vaccine (oral)
• Four doses: one capsule every other day for a week
(day 1, day 3, day 5, and day 7). The last dose should
be given at least 1 week before travel to allow the
vaccine time to work.
• Swallow each dose about an hour before a meal with a
cold or lukewarm drink. Do not chew the capsule.
• A booster dose is needed every 5 years for people who
remain at risk.
Either vaccine may safely be given at the same time as
other vaccines.
 4 Some people should not get
typhoid vaccine or should wait.
Inactivated typhoid vaccine (shot)
• Should not be given to children younger than 2 years
of age.
• Anyone who has had a severe reaction to a previous
dose of this vaccine should not get another dose.
• Anyone who has a severe allergy to any component of
this vaccine should not get it. Tell your doctor if you
have any severe allergies.
• Anyone who is moderately or severely ill at the time
the shot is scheduled should usually wait until they
recover before getting the vaccine.
Live typhoid vaccine (oral)
• Should not be given to children younger than 6 years
of age.
• Anyone who has had a severe reaction to a previous
dose of this vaccine should not get another dose.
• Anyone who has a severe allergy to any component of
this vaccine should not get it. Tell your doctor if you
have any severe allergies.
• Anyone who is moderately or severely ill at the time
the vaccine is scheduled should usually wait until they
recover before getting it. Tell your doctor if you have
an illness involving vomiting or diarrhea.• Anyone whose immune system is weakened should
not get this vaccine. They should get the typhoid shot
instead. This includes anyone who:
- has HIV/AIDS or another disease that affects the
immune system,
- is being treated with drugs that affect the immune
system, such as steroids for 2 weeks or longer,
- has any kind of cancer,
- is taking cancer treatment with radiation or drugs.
• Oral typhoid vaccine should not be given until at least
3 days after taking certain antibiotics.
Ask your doctor for more information.
 5 What are the risks from
typhoid vaccine?
Like any medicine, a vaccine could cause a serious
problem, such as a severe allergic reaction. The risk
of typhoid vaccine causing serious harm, or death, is
extremely small. Serious problems from either typhoid
vaccine are very rare.
Inactivated typhoid vaccine (shot)
Mild reactions
• Fever (up to about 1 person in 100)
• Headache (up to about 1 person in 30)
• Redness or swelling at the site of the injection (up to
about 1 person in 15)
Live typhoid vaccine (oral)
Mild reactions
• Fever or headache (up to about 1 person in 20)
• Stomach pain, nausea, vomiting, rash (rare)
 6 What if there is a serious
reaction?
What should I look for?
• Look for anything that concerns you, such as signs of
a severe allergic reaction, very high fever, or behavior
changes.
Signs of a severe allergic reaction can include hives,
swelling of the face and throat, difficulty breathing,
a fast heartbeat, dizziness, and weakness. These
would start a few minutes to a few hours after the
vaccination.
What should I do?
• If you think it is a severe allergic reaction or other
emergency that can’t wait, call 9-1-1 or get the person
to the nearest hospital. Otherwise, call your doctor.
• Afterward, the reaction should be reported to the
Vaccine Adverse Event Reporting System (VAERS).
Your doctor might file this report, or you can do it
yourself through the VAERS web site at
www.vaers.hhs.gov, or by calling 1-800-822-7967.
VAERS is only for reporting reactions. They do not give
medical advice.
