 Giving vaccine with or without Rabies Ig (RIG) depending on the level or category of exposure.
Guiding Principle:

 All clinically significant Adverse Events Following Immunization (AEFI) shall be reported to the
AEFI Surveillance and Response System.
Management of Rabies Exposure

 No absolute contraindications to rabies PEP (even pregnancy and infancy)
 Babies who are born to a rabid mother should be given a vaccination as well as RIG as early as
possible

Active Immunization

FCM 3
SUMMARY: 1st Shifting
Intramuscular Regimen

and those taking chloroquine and systemic steroids
2 of 9

Standard Intramuscular Regimen – Essen

Rabies Immunoglobulin (RIG)
 ERIG / HRIG
Given to patients with Category III exposures
Indicated for immunocompromised individuals (with HIV Infection, cancer/transplant patients,
patients on immunosuppressive therapy)


Passive Immunization
Administration:

Skin test must be performed prior to ERIG administration (0.02 ml of 1:10 dilution solution)\
 A positive skin test is an induration of >6 mm surrounded by a flare/erythema

Give HRIG

Indications of HRIG:
History of hypersensitivity to equine sera
Multiple severe exposures especially where the dog is sick or
suspected of being rabid
Symptomatic HIV infected patients

In case of anaphylactic reaction, give adrenaline/epinephrine (0.5 ml of 0.1 per cent solution)
 1 in 1000, 1 mg/ml for adults
 0.01 ml/kg body weight for children,

RIG should be administered at the same time with the first dose of rabies vaccine (Day 0).
 If RIG is unavailable on Day 0, it may still be given until 7 days after the first dose of
the vaccine (Day 0).
 Beyond Day 7, RIG is not indicated because an active antibody response has already
started and interference between active and passive immunization may occur
