you are asking a binary question. Have vaccines saved millions of lives or not?. Yes or no. This is the wrong question.
So If you want these diseases to come back don't get vaccinated. "
your lack of insight is dangerous because of its shallow thinking. Vaccines ARE NOT a guarantee.
From the CDC's own website.
Q: Can a child get a disease even after being vaccinated?
A: It isn’t very common, but it can happen.
About 1% to 5% of the time, depending on the vaccine, a child who is vaccinated fails to develop immunity. If these children are exposed to that
disease they could get sick. Sometimes giving an additional vaccine dose will stimulate an immune response in a child who didn’t respond to one
dose. For example, a single dose of measles vaccine protects about 95% of children, but after two doses almost 100% are immune.
Sometimes a child is exposed to a disease just prior to being vaccinated, and gets sick before the vaccine has time to work.
Sometimes a child gets sick with something that is similar to a disease they have been vaccinated against. This often happens with flu. Many viruses
cause symptoms that look like flu, and people even call some of them flu, even though they are really something else. Flu vaccine doesn’t protect
from these viruses.
Q: Can a child actually get the disease from a vaccine?
A: Almost never. With inactivated (killed) vaccines, it isn’t possible. A dead virus or bacteria, or part of a virus or bacteria, can’t cause
With live vaccines, some children get what appears to be a mild case of disease (for example what looks like a measles or chickenpox rash but with
only a few spots). This isn’t harmful, and can actually show that the vaccine is working.
A vaccine causing full-blown disease would be extremely unlikely. One exception was the live oral polio vaccine, which could very rarely mutate and
actually cause a case of polio. This was a rare but tragic side effect of this otherwise effective vaccine. Oral polio vaccine is no longer used in
