Is it necessary to receive the hemorrhagic fever vaccine?

Vaccines are generally administered to prevent specific infectious diseases, and the hemorrhagic fever vaccine is no exception—it targets epidemic hemorrhagic fever (EHF). This disease is typically caused by a naturally occurring virus transmitted to humans via a vector (e.g., rodents), leading to severe renal impairment and potentially life-threatening complications. So, is the hemorrhagic fever vaccine necessary? Below is a detailed explanation.

Is the Hemorrhagic Fever Vaccine Necessary?

The hemorrhagic fever vaccine is not classified as a Category I vaccine under China’s national immunization program and therefore is not mandatory for all individuals. Vaccination decisions should be based on individual circumstances. In China, EHF is primarily transmitted by rodents; thus, vaccination is highly recommended for individuals who frequently interact with natural environments—especially those residing in or traveling to endemic areas. This includes forestry and pastoral workers operating outdoors in affected regions, military personnel stationed in such zones, and others planning to enter endemic areas for any reason. Conversely, individuals with no exposure to endemic areas or populations need not receive the vaccine.

Knowledge Extension: Key Considerations for Hemorrhagic Fever Vaccination

1. Hemorrhagic fever vaccines are generally categorized into Type I and Type II. Type I vaccination primarily targets high-risk populations in endemic areas, typically aged 10–70 years—for example, construction workers at water conservancy projects or forestry workers in affected regions. Mild adverse reactions—such as low-grade fever or rash—may occur post-vaccination but are not common.

2. Certain contraindications must be observed before administering the hemorrhagic fever vaccine. Individuals with active fever should not receive the vaccine. Likewise, those with chronic infectious diseases, impaired hepatic or renal function, pre-existing liver or kidney disease, or known hypersensitivity to this vaccine—or those with a history of allergic constitution—should not be vaccinated.

3. Within one week following hemorrhagic fever vaccination, avoid consuming spicy or stimulating foods and beverages—including coffee and strong tea—as these may interfere with vaccine efficacy. During this period, it is advisable to consume fresh leafy green vegetables, such as spinach, broccoli, celery, and Chinese cabbage.

The above outlines whether the hemorrhagic fever vaccine is necessary. We hope this information is helpful to you.
