According to World Health Organization (WHO) guidelines, once a previously vaccinated individual completes a 2-dose booster course (on Day 0 and Day 3), their body achieves a rapid 'anamnestic' response, pushing antibody levels well above the protective threshold. Since you just received your doses on April 18th and 21st, your body is currently at its maximum immune peak. There is absolutely no clinical requirement to restart the course or take a 3rd dose for today's incident."
Next Steps
The 3-Month Grace Period: Once you complete a documented re-exposure course (0, 3), you are generally considered protected for any subsequent minor exposures for the next 90 days. Today's incident is covered under the protection provided by the April 18/21 shots.
Peak Antibodies: Your 2nd dose was on April 21st. By April 24th/25th, your immune system has already fully recognized the antigen and is flooded with protective antibodies. Adding another dose now provides no additional benefit.
Low-Risk Incident: As discussed before, 'saliva in eyes' from an indirect or non-bite source is a Category I/Low-risk event. With your very recent boosters, the risk is clinically zero.
Health Tips
Cancel Tomorrow's Dose: You do not need to go for the dose on April 25th. Save your record of the April 18th and 21st injections; they are sufficient for your protection.
Wound/Eye Care: If saliva actually entered your eyes, simply washing them with clean water or saline is enough. Do not use harsh soaps or chemicals in the eyes.
Immunological Memory: Your body now has strong 'memory cells.' If you have a significant Category III bite after 3–6 months, you would only then need to consult for a fresh 2-dose booster.
