If there is a dog bite again, from which day should we count? First day of previous (ARV) vaccine or last days? I'm worried

It's counted from the day 28 ,last dose of the ARV vaccine series.If there's a re exposure during this period,a booster dose on day 0,2 is required.Beyond that you have to have complete ARV vaccine series

The 90 days is counted from the last dose day 28 of your previous ARV schedule.
If a bite or an exposure happens
Within 3 months of last dose only 2 booster doses day 0 and 3 are needed
After 3 months full vaccination may be required again
No need to worry, you are protected if within this period.
If you’ve had a recent exposure, book a consultation so I can guide you exactly what to do.

For safer side I recommend to take again Anti rabies vaccine if bitten by unknown dog
No need to take risk as you don’t know titre of previous vaccine in your body so practically do not follow 90 days window

The 90-day (3-month) observation rule for Anti-Rabies Vaccination (ARV) is a safety window where your body maintains a high level of protective antibodies. If a re-exposure (another dog bite) occurs within 90 days of your last dose (Day 28), you generally do not need a full fresh course of vaccines. The countdown for this 3-month protection period always begins from the date of the last injection of your completed 4-dose or 5-dose schedule, not the first day.
Next Steps
Peak Immunity: Your body reaches its maximum antibody concentration shortly after the final booster dose. Therefore, the 'safety shield' is calculated from the point the full course is completed.
WHO Guidelines: According to standard protocols, if a bite occurs within 3 months of a documented, completed PrEP or PEP course, only local wound care is usually required.
Re-exposure Protocol: If a bite happens after the 90-day window, you would typically only need two booster doses (on Day 0 and Day 3) rather than the full schedule again.
Health Tips
Keep Records: Always keep your vaccination card safe. The exact date of your last dose is the most critical piece of information for any future doctor.
Wound Care First: Regardless of the 90-day rule, if a dog bites you again, the first step is always washing the wound with soap and running water for 15 minutes.
Don't Worry: If you completed your 4-dose IDRV schedule correctly, you are well-protected for this 3-month window.

The 90-day period is counted from the last dose (day 28) of the completed anti-rabies vaccine schedule, not from the first dose.
If a dog bite occurs within 90 days from the last dose, only booster doses (day 0 and day 3) are required.
If the bite occurs after 90 days, full post-exposure prophylaxis should be considered as per guidelines.
Next Steps
Please ensure immediate wound washing with soap and water for 15 minutes after any bite and consult a doctor promptly.
