Hello. Thank you for your query at Doctorspring.com
I understand your concern and i also appreciate that you're so aware about the possibility of acquiring infectious diseases from bat bites. That automatically reduces the chances of getting a full blown disease or complications by half.
In your case i feel since you already had an exposure before, it might be a little stressful for you to see bats and each time you come close to a bat, you may feel that it is going to bite you. From the way you described, it seems a little paranoid. But i completely understand and aceept this behavior is normal because you recently got all the shots.
The thing is mostly you will be able to tell if there is an exposure, since firstly there will be a small scratch which will slowly turn red and the area will appear inflamed after a point. But as you said at times it can be unnoticeable and a small scratch can be missed.
Now you need to really think and find out, because once thing that you would have definitely felt is the actual bite like a pin prick. If you felt something like that, then you can go ahead and take the post exposure prophylaxis. The recommended shots start from Day 0, hence you can go as soon as possible. Normally previously vaccinated people are given two additional doses in their deltoid and they are never given the HRIG again. Do you remember your schedule?
The incidence of such cases actually being positive with rabies is very low, because these kind of bats bite frantically, and you should have had a lesion. So now it is upto you to actually try and recollect if the bat was in any way in contact with you.
Hope this is helpful,
Regards

Hello. Since you have been exposed to the bat but unsure of a scratch or a bite, according to guidelines you can receive rabies post-exposure prophylaxis. It has to be started as soon as possible. You will require two shots of rabies vaccine on the deltoid muscle, on day 0 and on day 3. This is the schedule for you as you have been previously immunized against rabies. You will not the Human Rabies Immunoglobulin (HRIG) as I mentioned earlier. You need to get the first shot as soon as possible and cannot wait till Monday. Kindly go to the nearest hospital for the same. After these two shots, you are unlikely to be immune for life. Immunity after rabies vaccination varies among individuals. As long as you have an acceptable antibody level, you will likely be immune. In the future, if you are again exposed to a risk of rabies which requires vaccination, you will have to take the 2 shots. Thank you.
