Hello, I am actually concerned that when I was going on road, I felt a drop of liquid fall in my eyes. There were many monkeys on the trees eating, playing, etc. I am afraid if it was saliva of one of the monkey whi was eating something, do I need to get vaccinated. Two months before, I have taken two shots on days 0 and 3 as I had been previously vaccinated by 5 shots when a dog bit me. Please advise, if vaccine still effective.
