Yes — the intradermal (ID) 4-dose course you completed on 9th February acts as a full post-exposure prophylaxis (PEP).
After completing a proper PEP schedule, protective rabies virus–neutralizing antibodies (RVNA ≥0.5 IU/ml) develop within 7–14 days and provide strong protection for at least 3 months, usually much longer.
So from 9th February onward, you are considered adequately protected for 3 months against new exposures (as per WHO guidance for previously vaccinated individuals).
You have already taken multiple complete courses (5 doses in November + booster course Jan–Feb), so your immune response should be robust.
Next Steps
If a new bite/scratch occurs within 3 months of 9th February:
• No need for full PEP again
• Usually no vaccine required
• Just wash the wound thoroughly
If exposure occurs after 3 months:
• Only 2 booster doses (Day 0 and Day 3) are required
• No RIG needed
Avoid taking repeated full courses unnecessarily — it does not increase protection further and only increases anxiety.
Health Tips
• Do not repeat rabies IgG testing — routine antibody testing is not required unless immunocompromised.
• Excessive repeated vaccination is not harmful but medically unnecessary.
• Focus on proper wound washing (15 minutes soap + water) — this is the most important step.
• If you work in high-risk settings, consider pre-exposure schedule planning rather than repeated PEP.
Based on your vaccination history, you are well protected at present.

Since you have completed the full rabies vaccine course again recently, you are well protected. Protection does not last only 3 months — it usually gives good immunity, and in case of future bite within a few months, only booster doses may be needed.
Still, please consult me directly so I can review your dates properly and guide you for correct future protection.

Rabies vaccine and rabies immunoglobulin are 2 different things.
Usually Immunoglobulin is the one that is given Intradermally, which provides immunity for 21 days.
However Rabies vaccination can also be given Intradermally, but is rare in India.
Next Steps
Confirm whether you got Rabies vaccine or Immunoglobulin.
