In a Dec. 4 "Bad Astronomy," Phil Plait implied that autism rates were studied in vaccinated versus completely unvaccinated children, but the major study done was only for children given the MMR vaccine versus those who were not.

This is incorrect. An interactive map from the pro-Palestinian Israeli human rights organization B'Tselem indicates that an Israeli barrier round E1 would close non-barriered Palestinian access to East Jerusalem and would block direct access between Ramallah and Bethlehem, but it would leave a 10-mile-wide eastern strip connecting the northern and southern portions of the West Bank.
