I read something about combining two different adjuvants at the same time. Maybe that is why.
(I think this is the link)
I meant to include this snippet ---
"It is very important to note that administration of more than one aminoglycoside, such as neomycin, polymyxin, or gentamicin, is not advisable. In fact, it is even listed as a major drug interaction. (13) One can only imagine what could happen if a healthcare professional were to administer an H1N1 vaccine in conjunction with a seasonal flu vaccine or any other vaccines on the same day. Fluarix (14) and Flumist (15) are two U.S. licensed seasonal flu vaccines on the market today that both contain gentamicin sulfate. Common childhood vaccines, Pediatrix (16) and Pentacel (17) contain neomycin and polymyxin b sulfate. Furthermore, when aminoglycosides are administered with any other drugs or chemicals that alter kidney function, the toxicity is far greater, as well as the risk of having complications, such as ototoxicity (ear poisoning). (18) Other medications that may alter kidney function include non-steroidal anti-inflammatory drugs (such as ibuprofen or naproxen) or cholesterol lowering medications. (19) Non-steroidal anti-inflammatory drugs are also found in many cold and allergy preparations as well. (20)"
"Wouldn't these warnings apply to other vaccines that are already approved for administration at the same time?"
What agency approves the schedules? And how often do they review? Because we know they add new vaccines to the schedule all the time, but rarely do they take one off the schedule. I wonder, the vaccine approval committee - do they approve the use of each vaccine and then approve the schedule too? Or does the FDA handle the approval of each vaccine and the AAP create and approve the schedule? How does it all work, anyone know?
Here is what I have from the Dept HHS. It is a power point presentation.
