Question about Haneda Koji (spoilers included)

[alyaboulenein]

How come Haneda Koji's name was on the  APTX 4869 list when he was supposed to have died 17 years ago? Didn't Vodka say in the first episode that Shinchi was the first one to take the "experimental drug"?

Because Kohji was drugged with the earlier prototype of aptx4869 which was created by shiho's parents. Shinichi was given haibara's aptx which she created using remaining data of her parents' research.
