I hope all the people that think vaccinations are not effective should not take them, they may get sick and die, thereby ridding the planet of the VERY DUMB. Humans have no natural predators, and therefore need to have some mechanism to cull the herd. Viruses are perfect for the job. You could argue that's what a virus is for. If you don't want to be vaccinated... please don't, thus improving the genome for the rest of us. Way too many stupid people in the world... they are bringing down all of us.
