Merck hot lot MMR vaccine Question

[Guest guest]

Hi All, We contacted the doctor who gave our son the MMR vaccine,

that made him regress into severe autism, in l996. We obtained the

manufacturer's name and lot number. Can someone help us with this

and advise us how to find out if this was a hot lot and the possible

contamination? We have researched hot lots on the web, and now our

heads are spinning. The manufacturer was Merck, Sharp, and Dohme.

Lot number was 1168 B. The expiration date was 9-7-97. We would

appreciate someone telling us how to go about doing this, or any

advice. Thank you. Rose and Albert
