So I was looking into Boostrix (GSK) vs. Adacel (Sanofi) & it appears they use two different types of Aluminum. Sanofi is using AlPhosphate, 0.33mg (Tdap) & GSK is using AlHydroxide 0.4mg (Tdap)<br><br>
Then I went to CHOP's page & it seems that only 1% of an ingested dose of Aluminum is absorbed. So those dosages would be akin to me ingesting 33 or 40 mg. It seems clear that ingesting AlPhosphate is preferable, as it is less absorbed, but does that apply to injection?<br><br>
This is all about PreNatal Tdap. Another question I have is: where can I see *current* Pertussis stats in my location? Would I just call my local HD?

Well I am still really struggling with this: I have another 4 weeks to decide. On one hand, the dose in Adacel is 0.33mg, however I would have to eat 33 mg in one sitting to get that dose by ingestion (as only 1% is absorbed) & that would pretty much never ever happen. I wish I could find out whether the entire 0.33mg will be transferring promptly across the placenta?

<p>Here is some more to read. It is really awkward that the only mice experiments I found were conducted using aluminium chloride.</p>
<p>For aluminium phosphate and aluminium hydroxide I could only find studies for ingesting it. Not even the FDA has put a label on it:</p>
<p>'Aluminum hydroxide and magnesium hydroxide have not been formally assigned to a pregnancy category by the FDA. There are no controlled data in human pregnancy.'</p>

<p>Following. Just wanted to say that I was looking into info on this earlier this year as well (when my kids were supposed to get their dT) and couldn't find anything comparing the pharmacological action of the two types, injected, and if they were metabolized differently, excretion differences etc. I haven't found what I was looking for to date.</p>

When aluminium is given as part of an IV infusion up to 40% is retained in the body (the rest is secreted via the kidneys) of adults. Can be up to 75% in newborns. When given IM, the excretion rates are probably closer to the IV rates than the oral.<br><br>
Aluminium does cross the placenta and accumulate in the foetus in animal models so it is reasonable to assume it does in humans as well. I haven't been able to find any data on the amounts one could expect - I imagine it doesn't exist. The study methods required more or less preclude ethical human trials.

Scary: that link makes it seem like, since average Aluminum intake is 3-5mg/day & being injected with 0.33mg is the equivalent to consuming 33mg in one day (as only 1% of injected dose is absorbed), that this would be 10x my average daily dose.<br><br>
It also says that it *can* cross the placenta, especially in the 3rd trimester. . . . After it is absorbed by the mother . . .<br><br>
I really am still into this as a prevention strategy, but the Auminum exposure pre vs. postnatally doesn't seem that ideal.<br><br>
If the baby excretes what is passed through the placenta, seems like it would continually recirculated?

<br>
There would be some degree of recirculation as whatever is excreted in the urine would go into the amniotic fluid and be swallowed. However, since most orally ingested aluminium is excreted in faeces then, I imagine, it would accumulate in the meconium. Thus, it would be taken out of circulation and stored, as it were, in the mec until after birth.

This study compared the distribution and excretion of AP vs. AH over a month's time following a single injection in rabbits. More aluminum is absorbed when AP is used than AH.<br><br>
I'm on my phone so this is the best I can do for now.

 

[cwill]

<p>Here is the full text of that study.  <a href="https://www.physics.purdue.edu/primelab/research/publications/FL97A.doc" target="_blank">https://www.physics.purdue.edu/primelab/research/publications/FL97A.doc</a></p>
<p> </p>
<p>It's obviously a pretty limited study.  Unfortunately, the full text doesn't include figures so the raw data is not available and I haven't been able to find them.  But they did find that absorption via IV was much, much higher than via IM injection (600 ng/mL vs. 2 ng/mL).  So that addresses the IV vs. IM question. </p>
<p> </p>
<p>They also say</p>
<div class="quote-container">Quote:
<div class="quote-block">
<div> The normal plasma aluminium concentration in rabbits is 30 ng/ml (10).<span>  The maximum increase in the plasma aluminium concentration from the 0.85 mg aluminium doses of either adjuvant was approximately 2 ng/ml.  This small increase would have been masked by the aluminium background if ²⁶Al-labeled adjuvants were not used.  If the same dose of these adjuvants was administered intramuscularly to adult humans, an increase in the plasma aluminium concentration of about 0.04 ng/ml could be expected based on the larger blood volume of humans and assuming the same rate of dissolution in interstitial fluid.</span>"</div>
</div>
</div>
<p> </p>
<p>But this is where my lack of knowledge about toxicology or pharmacokinetics comes in.  More AP is absorbed than AH, but more AP is excreted in the urine than AH.  So ... where is the AH if it's not in the plasma or tissue or urine? </p>

 

[cwill]

<p>Thanks a lot dinahx, now I can't stop.  Here's another study comparing injections of AP and AH in monkeys: <a href="http://www.sciencedirect.com/science/article/pii/S0264410X04006887" target="_blank">http://www.sciencedirect.com/science/article/pii/S0264410X04006887</a></p>
<p> </p>
<p>I can't get the full-text, sorry.</p>
<p> </p>
<p>So it sounds like AP is absorbed and excreted more rapidly than AH and is less likely to cause local reactions - or at least the local reactions don't persist as long.  I'm not sure what effect a local reaction would have on your baby, which is ultimately what you're interested in, right? </p>
<p> </p>
<p>This review is also interesting and fairly easy to read: <a href="http://www.nature.com/icb/journal/v82/n5/full/icb200476a.html" target="_blank">http://www.nature.com/icb/journal/v82/n5/full/icb200476a.html</a></p>
<p> </p>
<p>It talks about the clearance rate, but also talks about why local reactions occur and mentions studies that looked at the effects of vaccines with and without the aluminum adjuvant.</p>

Could you please please please let me know finally which vaccine did you take Boostrix or Adacel and how did everything go?? Im stuck exactly like you.

You are replying to a post from 2013 so the chances are you won't get a response.

I'm so sorry that you're struggling with this decision during a time that should be as stress free as possible.



It sounds like you are fairly set on the idea of getting vaccinated with one or the other vaccines. Your post made me want to respond because of something that just happened over the weekend.



I recently saw a very "brand new," baby at a rather large, crowded, indoor function. I was thinking about how mislead and uninformed new moms are about the ability of vaccines to keep their infants infection free.


I just wanted to share a couple of things



https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880100/

Acellular pertussis vaccination facilitates Bordetella parapertussis infection in a rodent model of bordetellosis

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5440125/

https://www.ncbi.nlm.nih.gov/pubmed/30459769
Outer-Membrane-Vesicle-Associated O Antigen, a Crucial Component for Protecting Against Bordetella parapertussis Infection.

Maybe you have already considered the above?


I suspect parapertussis infections will become a more familiar topic as they move closer to gaining approval for a vaccine.



Prayers for a healthy, happy outcome!
