Have you ever used orphans to study an experimental vaccine?

Yes.

Have you ever used babies of mothers in prison to study an experimental vaccine?

Yes.

Have you ever used individuals under colonial rule to study an experimental vaccine?

Yes.

Did you do so in the Belgian Congo?

Yes.

Have you ever expressed that it's better to perform experiments on those less likely to be able to contribute to society?

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 that was a long time ago.
