Let’s try to put over this concept like this,lets say for purposes of a discussion that central Seattle (Washington) was experiencing high rates of Rabies.So the authorities decided to step in and vaccinate.So on a certain day at s certain time they went into a tower block and vaccinated everyone.
3 weeks later they thought they would check it,they went back to the tower block and found all of those actually had rabies.
Could you conclude anything about that vaccine??
Cos that is pretty much the situation
