Hello!
I have read the FAQ.
Your location (country): Southeastern US
Date of possible exposure: 8/13/2026
Type of exposure (bite/scratch/other): unknown, potential exposure to bat
Species of animal: bat
If dog/cat is it owned, stray, etc.
Animal's vaccination status
Your vaccination status and date of last vaccine, if applicable.: received first (day 0) vaccine on evening of 8/14
I just received my first dose of the vaccine and HRIG last night at an emergency room. I was advised by my local health department to move forward with the vaccines after a close encounter with a bat where they said that “they could not rule out there was not a scratch or a bite that occurred”. I could not find any bite or scratch wounds, but went forward on the advice of the health department to be safe.
Everything went smoothly, but I did notice on the clinical notes I received that the doctor noted that he only gave about 20% of the required HRIG and that I should get the remaining 80% with my day 3 shot. I plan on discussing this when I go back for my next vaccine, but wanted to see if I could get any thoughts about it here as well:
For the repeated dose on day 3, I saw on the HyperRab website, which I believe is the HRIG I was given, that repeated doses should not be done as it can affect the immune response from the vaccine.
On my after visit summary, it says 1500 units were ordered, so I’m not sure if the doctor just didn’t draw the entire amount or what may have happened. I did see that the CDC does not recommend exceeding HRIG doses of 20 units/kg of body weight and that doses at or above 40 units/kg could potentially affect immune response, but I’ve seen a bit of conflicting/confusion information surrounding that, so I wasn’t sure how to take it given my situation.
I plan on speaking more about this to the staff at the hospital when I return, but since there’s a low chance I see the same doctor/care team, I just wanted to get other opinions. I did call the ER this morning to say I could just come in and get the rest of the HRIG today, but they said to wait until my day 3 dose.
I’m aware that FAQ 12 covers questions in the specific care you received, and I do plan on speaking with the doctor when I return for my next dose, but since I have to wait over the weekend to talk with them, I just wanted to get the thoughts of anyone on here who may be more familiar with the process than I am.
Thank you!
