Seeking advice - Nurse gave infant adult vaccine.
🧐 Research Wanted 🤔
My wife took our child in for a 1 month appointment. They asked my wife if she wanted to give the child the RSV antinbody shot and she agreed. Later that day the doctor called and said the nurse mistakenly gave a full dose of the adult RSV vaccine. I don't what to do. Im tracking down what brand they gave and what lot number, ill update asap.
I am not sure why they would have adult doses of RSV antibodies at a peds office. But if you have the dose they administered and the specific name of the antibody, I would call poison control at 1-800-222-1222. They will be more than happy to discuss it!
Vaccines are not manufactured in pre-measured exact doses for different ages. The bottle comes with a certain amount of liquid vaccine in it at a certain concentration, and you vary the dose by varying the volume that you inject.
For example, the proper dose for an infant might be 0.1 ml, and the proper dose for an adult might be 0.3 ml. Both injections are taken from the same bottle. What OP is saying is that his baby was injected with the adult volume instead of the infant volume.
Big Pharma is pushing the 'new' RSV vaccine for people over 65 very hard right now. Which, by the way, is complete bullshit because RSV is only potentially dangerous the first time you get it, which will 99.9999999% of the time be as a young child or infant since we all get infected by it almost every cold and flu season for our entire lives. Once you've had it the first time, you develop lifelong antibody protection and only get cold symptoms that can't be told apart from a common cold without expensive testing. As long as your immune system is functioning properly, RSV is never a danger except possibly the very first time you get it as a child.
I get it I am a physician. But the new rsv shots like nirsemivab are antibodies not vaccines and the amount of medication that should have been in one vial is the 50 mg per 0.5 ml for a neonate. The dose the child should have received would be 50 mg the entire vial. This is not a large amount of volume for a child. They would have had to inject multiple vials which seems insane to me!
Unless the brand you are familiar with is not the only brand of RSV vaccine available, and other manufacturers are not producing single-use vials like that. Vaccines traditionally have been produced in vials containing a volume equating to a set number of adult doses per vial. 10 doses per vial is a common volume for many vaccines.
And I understand the difference between antibodies and vaccines, but I see no reason (other than safety) why an antibody infusion would be manufactured in different vials than vaccines, especially since they're marketing it as an 'RSV vaccine', not an 'RSV antibody infusion'. Single use vials are definitely safer in order to prevent the type of mistake made by the OP's pediatrician, but single use vials are also a lot more expensive per dose to produce. Some companies may take the hit to their profit margin in the name of safety, but I'd bet that not all of them do.
There are a few new antibodies being used in children for rsv. From reviewing package inserts etc it appears most are single use. But you are right if they are using multi dose vials they could easily screw up the dose.
