Au contraire, Monsieur Powerdoc! Kind of. Stay with me here. This is a bit complicated. And a bit odd.
While I have some vague memory of hearing about polio vaccine problems before, it was in the news here just the other day. I heard it being talked about on television, tuned in long enough to hear them say it only related to the the injected vaccine, thought "cool, I had the oral stuff, I don't have to worry about no monkey virus" and forgot about it until I read your first post referring to the polio vaccine. "Tee hee", I thought.
So I Googled up the Sydney Morning Herald article but then thought "nah he's a doctor we'll have to do better than that. What we need here is a reputable academic journal or two." I noted you referred to the oral vaccine as having problems but thought you were probably talking about some side effect that, as you would well know, occur with various vaccines in rare cases.
Anyway, I quickly found numerous references on the internets, picked out CDC
and New Scientist
as being sufficiently high calibre, posted my reply, and sat back to await your humiliating back down.
Imagine my crushing disappointment when, instead, I got slapped down. "Bugger", I thought. Not only am I going to have to admit I was wrong, it seems I may well have the monkey virus after all. How could I have got it so arse about.
So, I go back to the New Scientist
link to check. Damn!
Minor found three samples of the Soviet oral polio vaccine from the late 1960s in the NIBSC's freezers, the only samples known to survive from this time. In 1999, he found they tested positive for SV40, whereas British samples from this period did not.
Not only am I not sloppy with this sort of thing but this related personally to me. I was sure they'd said the injectable vaccine on the news and in at least one article I'd looked at. The abstract from Oncogene
revealed nothing and you have to pay to get the full text. I didn't expect to get third time lucky with CDC
. But I did!
Soon after its discovery in 1960, SV40 was identified in polio vaccine. It was found in the injected form of the vaccine (IPV), not the kind given by mouth (OPV).
Now while I'd love to snatch victory from the jaws of defeat because I think CDC
probably trumps New Scientist
plus a check back to the SMH
revealed I hadn't misheard the recent reports, I will:
1. Assume I've missed something while giving the articles no more than a quick scan
2. Defer to your superior knowledge and ask what gives? Is New Scientist
guilty of sloppy reporting? Are the Americans now trying to get their revenge on France by falsifying medical research?
3. Still be reasonably confident the problems with the vaccine you originally referred to weren't the monkey virus anyway. (Of course, that means you didn't look at my references very closely. But then we already know that don't we?
4. Wait until you tell me the answer given you can probably just ask some immunologist you know whereas I would have to go and actually read stuff.
Until then, I bid you adieu.
