1. Introduction to Speeda Rabies Vaccine
SPEEDA® is a next-generation purified rabies vaccine (Chromatographically Purified Rabies Vaccine – CPRV) that is purified using chromatography and produced from the PV-2016 rabies virus strain (a Pasteur virus strain provided by the U.S. CDC and recommended by the WHO), based on the principle of continuous Vero cell culture.
SPEEDA® has been on the market since 2005 and has broken the monopoly of multinational companies on premium human rabies vaccines in China, which currently leads the world in rabies cases. Over the years, the company has supplied more than 180 million doses of Speeda rabies vaccine worldwide. Most recently, this vaccine has been approved for intradermal administration using the TCR-ID regimen (The Thai Red Cross intradermal) in Thailand.
2. Target Users
Individuals bitten, scratched, or licked on broken skin by animals suspected of having rabies.
People at high risk of rabies virus exposure, such as veterinarians, animal quarantine officers, hunters, and those working in environments with a risk of rabies infection.
Travelers visiting regions with a high risk of rabies transmission.
3. Vaccination Schedule and Dosage
A. Post-Exposure Prophylaxis (PEP)
In case of an animal bite suspected of rabies, the vaccine should be administered according to one of the following regimens:
Essen 4-dose regimen (WHO recommended):
- Day 0: 1 dose (0.5ml) intramuscularly.
- Day 3: 1 dose (0.5ml) intramuscularly.
- Day 7: 1 dose (0.5ml) intramuscularly.
- Day 14: 1 dose (0.5ml) intramuscularly.
2-1-1 regimen:
- Day 0: Administer 2 doses (0.5ml each) at two different sites (both arms).
- Day 7: 1 dose (0.5ml) intramuscularly.
- Day 21: 1 dose (0.5ml) intramuscularly.
Combination with Rabies Immune Globulin (RIG):
If the wound is severe (deep bites, near the central nervous system, on the head/neck, or bleeding), rabies immune globulin should be administered on the first day (Day 0).
B. Pre-Exposure Prophylaxis (PrEP)
3-dose regimen:
- Day 0: 1 dose (0.5ml) intramuscularly.
- Day 7: 1 dose (0.5ml) intramuscularly.
- Day 21 or 28: 1 dose (0.5ml) intramuscularly.
If exposure risk persists, booster doses should be given every 1-3 years as recommended by a doctor.
4. Administration Guidelines
Injection site:
- Administer deep intramuscularly into the deltoid muscle for adults and children over 2 years old.
- For infants under 2 years old, the injection should be given in the anterolateral thigh muscle.
- Do not inject into the buttocks due to the risk of reduced immune response.
5. Important Considerations
- Follow the vaccination schedule strictly to ensure immunity.
- Do not use the vaccine in individuals with a history of allergy to any of its components.
- If a dose is missed, get a replacement as soon as possible following a doctor’s guidance.
- Avoid alcohol consumption during the vaccination period to prevent interference with vaccine efficacy.
- Seek medical attention immediately if severe side effects such as high fever or allergic reactions occur.
6. Why Choose Speeda Vaccine?
- Advanced technology: Produced using Vero cell culture, ensuring high purity and safety.
