Rabies Vaccination
Vaccination schedule
Pre-exposure vaccination is given by 3 doses of inactivated rabies vaccine on days 0,7,21 or
28 as standard primary series. Active immunity develops after the third
dose, therefore pre-exposure vaccination should be started one month before
travelling. Those who wish to take anti-malaria (chloroquine)
should preferably be given vaccine intramuscularly because concurrent
use of these drugs may affect the antibody response to intradermal vaccination.
Recommendations
Pre-exposure vaccination is recommended for prolonged trip to endemic
areas, particularly for visits to remote rural regions without medical
facilities, or people who will travel even for a short period in rabies
infected areas if their activities may involve some special risk (hiking,
cycling, trekking and animal handling). It should be noted that pre-exposure
immunisation does not eliminate the need for post-exposure immunisation.
Travellers should therefore seek local medical opinion if bitten by animals
abroad even when they had already received a course of pre-exposure immunisation.
Adverse reactions
Pain, reddness, and swelling or itching at the injection sites have been
reported among 30 - 70 % of recipients. Systemic reactions such as headache,
nausea, abdominal pain, muscle aches, and dizziness have been reported
among 5-40% of recipients. Anaphylactic shock and Guillain-Barre Syndrome
have been reported very rarely.
Contraindications
Pregnant women and persons with hypersensitivity to neomycin should not be vaccinated unless there is a high risk of the
disease or for post-exposure treatment. Persons who are immunosuppressed
by disease or medication should defer pre-exposure vaccination because
the immune response may not be adequate in such persons, and consider
avoiding risky activities afore-mentioned.
