The importance of high rates of vaccination

There are others who can probably give better answers, and some oft his has been addressed earlier in the thread.
My understanding, and my understanding of the underlying math and probabilities, is the concept of "herd immunity", and the probability of contagion.
In a population, there will always be some people without immunity to a dangerous disease, either due to compromised immune systems, ineffective response to the vaccine, or being a newborn baby, chemotherapy, etc.
Until the magic day that a disease is completely extinct, (as happened with smallpox in the 1970's, and we are close to for polio, but having serious trouble closing the gap), there will always be cases popping up randomly, due to people traveling, etc. If measles, say, is spread at random in a population vaccinated to a level over 90%, the chances of effective transmission drop below likely perpetuation.
Sadly, the vaccination ratesi n north America are now over 70%, due to the types of attitudes some have aired on this thread.
As has been mentioned earlier in this thread, whooping cough, a very vile and deadly disease is back in Manitoba as a result, and a measles outbreak is under way in Edmonton presently. Eventually I fear there will be deaths as a result, a shameful slip backwards.
That's why every person, and every child without a critical health reason otherwise, for the public safety, should get their vaccinations.
Imagine how horrible a person would feel if they learned that the whooping cough or measles they, or their kids transmitted ended up killing others?
Don raised a valid point earlier, pointing out that to be safe, various vaccinations should be boosted in adults, (though he didn't mention that the main reason this is necessary now is because the antivaxxers have so deeply compromised public health)...
Every responsible adult should be making arrangements with public health to be boosted particularly for whooping cough, and anything else they recommend.
And remember to thank the antivaxxers for endangering all our children and grandchildren when doing so.
