The role of the coincidence between timing of vaccine and disease onset was the focus of the Melchior study.  In the 1970s the DPT (diphtheria, pertussis and tetanus) vaccine was going through media hype. Similar to current scrutiny of the relationship between autism and MMR, early DPT vaccination was linked with claims of vaccine-induced neurological injury, because of the onset of infantile spasms (IS), an epileptic syndrome of childhood..  To dispel this temporal link, Melchior and colleagues sought to examine the effect on the onset of infantile spasms in Denmark by changing the timing of initiating DPT vaccine from 5 months to 5 weeks.  The study found that the mean age of onset of IS did not change together with the change in DPT administration. This proved IS was independent of vaccine administration [Melchor 1977].    With greater medical understanding, a greater proportion of IS cases were found to have specific causes (genetic or metabolic). This helped further break the perception of a link with vaccination.   As the mystery of autism and a better understanding of its biology is revealed, it is intended that the  perception of its risk linked to measles vaccines will also end.

I took my son to the dr last Wednesday for his 6 month appt & he got his shots along with the flu shot. On Sunday, my husband noticed dropping his head & told me about it-but thought there wasn't anything to worry about. Well, I'm a worry wart & started paying attention & I've been noticing that all of the sudden out of nowhere, its like he looses all control in his neck. It's like a person who is falling asleep sitting up & there head drops, but they catch it. He doesn't cry or anything when it happens-but his expression changes. I didn't really know what to call it, so didn't know how to look it up-but last night I started typing in "baby head drop" & came across infantile spasms. I"M FLIPPING OUT!!  I've called the dr. & am waiting on a call back. I explained to the nurse what was happening & showed her a youtube video of what it looks like-she said she would pass the info along-its been an hour already!!

I'm worried sick & been crying all morning. Has anyone else had this happen to their LO???
