Statistics from the recent Welsh measles outbreak:
"In the outbreak children who were unvaccinated had a chance of catching measles of around 1 in 18 (6,812/371), children who were partly vaccinated had a chance of catching measles of around 1 in 750 (14,219/19) and children who were fully vaccinated had a chance of catching measles of around 1 in 2,200 (68,825/31). This shows that 2 doses of MMR were over 99% effective in protecting against measles and 1 dose of MMR was over 97% effective in protecting against measles."

1400 measles notifications, 88 people were hospitalized and one died.
So the 95% number is the wrong way round and even with modern medicine and fast responses in a first world country a relatively small outbreak can be fatal.
