Hi Sir, I Have A Question Regarding Bites And Rabies.

Hi Sir, I have a question regarding bites and rabies. When I woke up on a Sunday morning 20 days ago, I found out that there was an injury on my hand, it looked like a scratch or a bite, it had several dots on it and it was red around the wound and not bleeding, I did not see any animals on that day or the day before, I was worried if it was a bat bite because I live in Canada but it had many dots and lines and it did not look like a bat bite, I have not seen a bat in my life and there was no bat in my house or around it. I had taken 5 doses of rabies vaccine 7 years ago and I just want to know how long does the vaccine last, will it still have immunity after 7 years? Thanks
