rabies PEP question

[tastrophe]

Anyone have any stats on how long the preexposure series actually lasts? I know you're supposed to have a titer done every 2 years, but I'm curious how many 2-year intervals normally pass before the antibody levels drop below the accepted value?

It varies greatly with each individual. I had my preexposure shots about 4 years ago when doing wildlife research and since then (due to my job) have had my titers checked every 2 years, and my Ab levels are till pretty high. A man I work with had his shots 12 years ago and he is still good to go with his titers too. Some people may not last that long though and some titers go down after even 4-5 years, so it just depends, but normally they stay within the acceptable range for pretty good amount of time.

My titer is still good 20 years after the original series. And I know one guy who never develops a protective titer. So like athane960 said, it varies tremendously.

I got my series in 2005 and am already nearing the low end of a protective titer.

I received the post-exposure series in 1999 and am at the low end of protective titer-dom.

Okay, so does anyone know what an acceptible titer level is?

Thanks for your help!

I had a post-exposure prophylaxis in 1975 when I brought a rabid bat home. My titers have been protective ever since.
