Last night, my finger was bitten and bled by my own teddy bear. I took a bite six months ago and got rabies vaccine. Do I need another fight?

After injecting people with rabies vaccine to produce antibodies, the immune validity period is 6 months, which means that if you are bitten by a dog again within 6 months after injection, you don't need to inject the vaccine.

If you are bitten by a normal healthy dog during the vaccination period or within 6 months after the vaccination test produces anti-rabies antibodies, you can immediately wash the wound thoroughly with a lot of soapy water without vaccination. If bitten by a rabid or suspected rabid dog, two doses of vaccine should be injected within 0 and 7 days.

If the landlord is bitten by a normal healthy dog within 6 months, he will be vaccinated and tested to produce anti-rabies antibodies.

So,

1. If you can confirm that the last vaccination was within 6 months, you don't need to inject again.

I'm not sure whether the last registration was within half a year or more than half a year. To be on the safe side, I'd better have another injection or call a professional doctor.
