Is fever a contraindication to administering the anti‑rabies vaccine Rabipur (human diploid cell rabies vaccine)?

Fever is NOT a Contraindication to Rabipur for Postexposure Prophylaxis

For postexposure rabies prophylaxis, there are no contraindications to administering Rabipur, including the presence of fever, because rabies is almost invariably fatal once symptoms develop. 1

Contraindications by Clinical Context

Postexposure Prophylaxis (After Potential Rabies Exposure)

• No contraindications exist for postexposure prophylaxis, including fever, pregnancy, or any other medical condition. 1
• The FDA label explicitly states: "In view of the almost invariably fatal outcome of rabies, there is no contraindication to postexposure prophylaxis." 1
• Given the 100% mortality rate of clinical rabies, the risk-benefit calculation always favors vaccination regardless of concurrent illness. 1

Preexposure Prophylaxis (Preventive Vaccination)

• Only a history of anaphylaxis to the vaccine or any vaccine component constitutes a contraindication to preexposure vaccination. 1
• Fever alone is not listed as a contraindication even for preexposure prophylaxis. 1

Management of Fever During Vaccination

• Fever is a commonly reported adverse reaction to Rabipur, occurring uncommonly (temperatures above 38°C/100°F). 1
• If fever develops after vaccination, it can be successfully managed with antipyretic agents without interrupting the vaccine series. 1
• Once rabies prophylaxis is initiated, it should not be interrupted or discontinued because of local or mild systemic adverse reactions, including fever. 1

Critical Clinical Principles

• The vaccine schedule must be completed as recommended: days 0,3,7,14, and 28 for previously unvaccinated individuals receiving postexposure prophylaxis. 2, 3
• Minor delays of a few days for individual doses are acceptable, but the series should not be abandoned due to intercurrent illness. 2, 3
• Human rabies immune globulin (HRIG) must be administered on day 0 along with the first vaccine dose for all previously unvaccinated individuals. 3

Common Pitfalls to Avoid

• Do not defer or withhold postexposure prophylaxis due to fever or any other medical condition—rabies mortality is essentially 100%. 1
• Do not confuse preexposure and postexposure contraindications; the latter has none. 1
• Do not discontinue the vaccine series if fever develops as an adverse reaction; manage symptomatically with antipyretics. 1
• Seek advice from state health departments or CDC only for management of serious adverse reactions (e.g., anaphylaxis, neurological events), not for common reactions like fever. 1
