It is best to start your travel shots early, as
the timing and spacing of vaccines can be lengthy and
quite complicated.
Cholera Vaccine is not usually recommended,
as it is relatively ineffective and confers such brief
partial immunity (2 - 6 months). It is given in a series
of two shots, one week to one month or more apart - the
last dose being as close to departure as possible. Occasionally
a single dose of vaccine is given to satisfy unusual
local vaccination requirements.
Hepatitis B Vaccine is recommended for
all college students and is given in a series of 3 injections
over 4 to 6 months. The first dose is given any time,
the second dose is given 1-2 months after the first dose
and the third dose 4-6 months after the first dose. Hepatitis
B is a serious disease which can cause long term (chronic)
illness. Hepatitis B virus is spread through contact
with the blood and body fluids of an infected person.
Hepatitis A (Havrix) Vaccine is given
in a series of 2 injections 6-12 months apart. The first
(primary) dose should be completed at least two to four
weeks prior to expected exposure to Hepatitis A virus.
The second (booster) dose, recommended 6-12 months after
the primary dose provides virtually 100% immunity for
at least 10-20 years and probably for life. Hepatitis
A is very wide spread worldwide and is contracted by
consuming contaminated food or drink or by direct person-to-person
contact.
Immune Globulin should be given as close
to departure date as possible and at least 14 days or
more after the administration of MMR (measles, mumps,
rubella vaccine), and at least three weeks after the
administration of varicella vaccine. I.G. is given to
prevent viral hepatitis A and lasts for no more than
4-6 months. Persons traveling to high risk areas less
than four weeks after their first dose of Hepatitis A
vaccine may wish to receive IG. When administered within
two weeks following exposure to Hepatitis A IG is more
than 85% effective in preventing Hepatitis A.
Influenza Vaccine may be desired for
travel November to April in the Northern Hemisphere and
May to October in the Southern Hemisphere. Influenza
viruses are active year round in the tropics. Protection
develops after about 2 weeks and may last up to a year.
Japanese Encephalitis is given in a
series of 3 shots at days 0, 7, and 30. The last dose
should be given at least 10 days before arrival in the
infected area. It should generally not be given the same
day as other vaccines. It will be necessary to wait at
the clinic 1/2 hour after receiving each dose to monitor
possible adverse reactions. Additional printed Japanese
Encephalitis information is available from the Immunization
Clinic.
Malaria No vaccine is available, but
travelers can protect themselves by taking an oral medication
to prevent malaria.
Meningococcal meningitis vaccine may
be given to travelers at risk, and college students who
choose vaccination to reduce their risk for potentially
fatal meningococcal disease. For international travel
it should be administered 1-2 weeks before departure.
The duration of protection is 3-5 years or possibly longer.
MMR (measles, mumps, and rubella) is
a live vaccine and should be given either the same day
or 28 days apart from Varicella and Yellow Fever vaccines.
Two MMRs after one year of age and at least one month
apart should confer lifetime immunity. It should not
be given for three months after getting Immune Globulin.
When Immune Globulin needs to be given following MMR
a waiting period of 2 weeks is recommended. Women who
receive MMR should not become pregnant for at least 3
months after immunization. Tuberculin testing (IDPPD),
if indicated, can be done on the same day or 4 to 6 weeks
following MMR.
Polio Vaccine (injectable) can be given,
once, to adults, who have previously completed a primary
series and traveling to countries where there is risk
of exposure to wild polio. Polio is a viral disease spread
by fecal-oral or oral-oral (respiratory) contact.
Rabies Vaccine (pre-exposure) If you
plan to stay for more than 30 days in a country where
rabies is a constant threat, especially if you travel
to remote areas, or if you travel to endemic countries
where rabies immune globulin or tissue culture vaccines
are unavailable you should strongly consider predeparture
rabies vaccination. Rabies vaccine is given in three
doses on days 0, 7, and either 21 or 28. Additional printed
rabies information is available from the Immunization
Clinic.
Tetanus-diphtheria (Td) is one of the
oldest and safest vaccinations. Tetanus boosters are
given routinely every 10 years. (In the case of a tetanus-prone
injury it may be repeated after five years). Tetanus
is an often fatal neuromuscular disease. Transmission
typically occurs via contamination of wounds, burns and
punctures.
Typhoid Vaccine may be given by single
injection or taken in a capsule form. Capsules must be
refrigerated and taken in four doses on days 0, 2, 4
and 6. Oral typhoid vaccine should be completed at least
one week prior to exposure. Oral vaccine immunity lasts
approximately five years. Injectable typhoid vaccine
should be received at least two weeks prior to exposure.
Injectable vaccine immunity lasts approximately 2 years.
Typhoid fever is contracted by ingestion of contaminated
food and water.
Varicella (Chickenpox) Vaccine Two doses
of vaccine given four to eight weeks apart are recommended
for healthy adolescents and adults with no history of
the disease. Varicella virus is endemic in most countries
throughout the world. Varivax is a live vaccine and it
should be given the same day or 30 days apart from MMR
or Yellow Fever vaccines. Varicella vaccine should not
be administered less than five months after receiving
Immune Globulin, and when IG follows Varicella Vaccine,
a waiting period of three weeks is recommended.
Yellow fever Vaccine is a live vaccine
and should be given the same day or 30 days apart from
MMR, Varicella or oral typhoid vaccines. It may be given
with, before or after Immune Globulin without restriction.
Yellow fever and cholera vaccines should be given at least
three weeks apart. After immunization, an International
Certificate of Vaccination is issued. To satisfy international
requirements, immunization must be given not less than
10 days and no more than 10 years prior to planned date
of entry.
