The 0-3-7-28 rabies vaccine schedule is a standard protocol for administering rabies vaccines to prevent infection. This calculator helps determine the appropriate doses and timing based on your specific situation.

What is the 0-3-7-28 Rabies Vaccine Schedule?

The 0-3-7-28 rabies vaccine schedule is a series of four doses administered at specific intervals to provide optimal protection against rabies virus infection. The schedule is typically used for:

Pre-exposure prophylaxis (PEP) for high-risk individuals
Post-exposure prophylaxis (PEP) after a potential exposure
Immunization of animals

Important Note

This schedule is a general guideline. Consult with a healthcare professional or veterinarian for personalized advice based on your specific situation and medical history.

Worked Example

Let's look at a typical example of a 35-year-old individual receiving pre-exposure rabies vaccination:

Example Scenario

For a 35-year-old with no medical conditions, the recommended schedule would be:

Day 0: First dose (0.5 mL)
Day 3: Second dose (0.5 mL)
Day 7: Third dose (0.5 mL)
Day 28: Fourth dose (0.5 mL)

This example shows the standard dosing pattern for a healthy adult. The actual dose size may vary based on specific circumstances.
