Have you ever used orphans to study an experimental vaccine?

Yes.

Have you ever used the mentally handicapped to study an experimental vaccine?

I don't recollect ever doing studies in mentally handicapped individuals.

At the time in the 1960s it was not an uncommon practice.

I'm not clearing your answer.

Have you ever used the mentally handicapped to study an experimental vaccine?

What I'm saying is I don't recall specifically having done that, but that in the 1960s it was

not unusual to do that and I wouldn't deny that I may have done so.

There's an article entitled Attentuation of RA273 Rebellivirus in WI-38 human diploid

cells.

You're familiar with that article?

Yes.

In that article one of the things it says is 13 seronegative mentally retarded children were

given RA273 vaccine.

Okay, well, that's in that case that's what I did.

Have you ever expressed that it's better to perform experiments and those less likely

to be able to contribute to society such as children with handicapped than with children

without or adults without handicaps?

I don't remember specifically, but it's possible.

And again I repeat that in the 1960s that was more or less common practice.

I've since changed my mind, but those were, that was a long time ago.
