But if vaccinations actually gave immunity - then why would people already vaccinated need more - and why wouldn't it work for people already vaccinated?

Vaccinations are not 100% effective for everyone. Also, some people cannot be vaccinated due to allergies. If the vast majority of the population is vaccinated, these people will be just fine.

You don't necessarily get lifetime immunity from a vaccine. For instance, I (and pretty much everyone else born before 1971) have a smallpox vaccine scar.

But the estimates I've heard are that only about 50% of the people who were vaccinated would have enough immunity to fight it off.

It's not an exact science. Immunity wanes over time. Experience has shown that a single vaccination for most diseases doesn't do the trick, IMHO.

I think they are just ticked that people are waking up about vaccines. The Medical establishment hates it when people start to think for themselves.

Because over time the effect wears off. And nothing is perfect. Thats why you need to get a tetanus booster about every 10 years.

It isn't that the vaccines aren't working .. it's that the illegals are bringing those diseases back to this country after we already got rid of them.

There is also an alarming increase in TB cases .. also brought from Mexico.
