"Once the percentage of vaccinated children drops low enough, herd immunity is compromised, and epidemics get a chance to occur and spread. We had some antivaxer here recently quoting a story about epidemics traced to unvaccinated teens bringing in diseases to their peer groups. He thought that was a sign of vaccines being useless - but what it really shows is how _not_ vaccinating puts everyone else at risk."
Do you have any scientific evidence, not paid for by vaccine manufacturers, supporting this claim?
That doesn't make sense that vaccinated people would lose immunity because there peers are sick and dying?
Also how do you explain that we are not vaccinated against 100's of infectious diseases, yet we are pandemic free...
TB is highly contagious, yet we do not have a pandemic here in N.America.
Most people are not immunized against it.
However 3rd world countries lacking sanitation and water treatment are plagued with TB. They also do not immunize.
