I am not sure about this. BUT if you can not get immunity from a disease, such as diphtheria, tetanus, pertussis, you will not show antibodies in the blood unless you are at the present time fighting the pathogens.<br><br>
Pertussis you can get repeatedly, so it only stands to reason that we create no antibodies or at best the antibodies have a very short duration.<br><br>
ETA: Although they tell you that they see antibodies after the pertussis vaccine, they have no way to proof that it is not merely a reaction to the adjuvants.<br><br>
But the proof is in the pudding: In a whooping cough epidemic, most kids afflicted had in fact been fully vaccinated.
I was wondering because I read on many schools' websites that for the vaccination requirements, they accept titers for proof of immunity for measles, mumps, rubella, chickenpox, and hepatitis B. But they don't mention titers for proof of immunity to pertussis. They also don't mention anything about a doctor's note saying you have already had the disease.<br><br>
I know there are always religious exemptions and also philosophical exemptions in many states, so I'm not worried, just wondering.
Yes, that makes sense.<br><br>
I've read about two moms who had their un-vaccinated child's titres done and guess what, their immunity was right up there with the vaccinated kids. And neither had had any childhood diseases that they knew of. So, we can have the virus, build antibodies, and not show the expected symptoms.<br><br><br>
Many doctors have suggested testing the kids before injecting on the chance that they have built antibodies on their own.
Funny timing on this thread as I just got my results back today.<br><br>
There is a pertussis titer that can be done on blood. Mine confirmed that I was exposed to pertussis and as such, am immune. (This was never diagnosed, it's just to confirm suspicions I had about a particularly intense cough I had when I was 13). From what I understand, these antibodies will pass through the placenta to the newborn, but unlike some others which circulate for a long time, these tend to phase out within weeks after birth. Regardless, if I were to consider giving the pertussis vax to my child, he would definitely be receiving the titer first to check for these antibodies.<br><br><img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/orngbiggrin.gif" style="border:0px solid;" title="orange big grin">

Cool! Now I wonder why the places I checked out don't mention a pertussis titer as an alternative to the vaccine? Maybe because it comes with diphtheria and tetanus, and they want you to get those too?
