1. You got a scratch from a stray cat with a little blood.
This type of exposure is considered Category II or III depending on depth, but in both cases, rabies vaccine is recommended.
You did the right thing by taking the vaccine.
2. You took the vaccine after 20 days.
Is it too late?
Answer: No — it is NOT too late. You are still protected.**
Rabies vaccine can be started even weeks after exposure, because:
• The rabies virus (if present) travels very slowly through nerves
• It usually takes weeks to months to reach the brain
• Vaccine given even after 10–30 days still prevents the illness
So starting on day 20 is absolutely acceptable and is medically effective.
You are safe.
3. Your schedule: 0, 3, 7 days
This is a valid WHO-approved intradermal or intramuscular schedule used in many countries.
A standard schedule is:
• Day 0
• Day 3
• Day 7
Sometimes a Day 14 dose may also be added depending on hospital protocol.
If the doctor gave you 3 doses, follow their plan.
Next Steps
Do you need Rabies Immunoglobulin (RIG)?
RIG (antibodies) is required if:
• The wound is deep
• There is bleeding
• It is a Category III exposure
• Vaccination is delayed more than 24 hours with a deep wound
You said it was a small scratch with little blood → most likely Category II, and RIG is not mandatory.
Your doctor judged correctly.
Health Tips
Most important point — Rabies is preventable. Since you took the vaccine, you are protected.
Rabies vaccine is extremely effective.
Late vaccination does not mean failure.
You have taken all the medically required steps.
You are safe now.
