Is this for real? Oy vey.

It's a mathematical relationship known as "herd immunity."
herd im·mu·ni·ty
noun
noun: herd immunity; plural noun: herd immunities
the resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease, especially through vaccination.
"the level of vaccination needed to achieve herd immunity varies by disease but ranges from 83 to 94 percent"

It's a question of ethics. When nearly the whole population is vaccinated, the disease is exceedingly rare. Those few who choose not to get vaccines benefit from the fact that most others have done so. The vaccinated have incurred certain risks and costs associated with the vaccine in return for disease protection; the unvaccinated incur none of the costs yet receive most of the benefits. They are, in effect, freeloading on the vaccinated. This is unethical.

There's also the obvious consideration that as the number of unvacccinated increases, the population as a whole suffers from less effective disease prevention. The unvaccinated are betting that most people will be responsible and get the vaccine. The more unvaccinated there are in the population, the more risky it becomes to go without . So it's in the interest of those who choose not to get vaccinated to make sure that others make the opposite decision. Again, this is freeloading and clearly unethical.

Genetics. Vaccines work when you get them but don't alter the genes and pass down to children. Germs and viruses still exist so continued vaccination still is necessary.

because the germ or virus is still out there and new babys need to be protected they don't die out and with the poles melting watch out for pandemics

with all the hand sanitizer and kids not playing outside its gonna be bad no immune systems in place

They can save your life.

You think because people get vaccinated that the bacteria which causes the diseases simply hops aboard a luxury space ship for a nice long vacation to Pluto?? Doesn't work that way. Vaccines don't make the disease go away. They just help the body build resistance to it.

1 . Because of adults, especially older ones, whoseimmunity may have gotten low.
2. Because of infants who may not yet be fully immunizeimmunized
3. Because when you choose to live in a society, you should not be part of the problem!

I am old enough to remember before polio could be vaccinated against, the fear in parents' faces as they cancelled yet another summer outing, being shown b&w movies about how much fun it was to live in an iron lung (still available on youtube!) after thursday lunch, yada yada.
Anti-vaccers are irresponsible assholes At Best!

Some people cannot get immunised such as babies and other special cases. When more people are vaccinated there's less chance for these people to catch the diseases .

I don't know... not a user.

It's to do with herd immunity, making the protected part of the population so large that the diseases can't thrive and also to protect the few who due to reasons beyond their control are unable to be vaccinated. Also the more people who don't vaccinate means there is a larger chance that disease causing agents mutate and overcome the protection that vaccines provide!

You're so right, LOL!

The Big Pharm medical society wants to make money on YOU.
All the time.
Throw people who take cannabis in jail, force alternate medicine doctors out of business, push toxic, addictive drugs!
Stop people from thinking for themselves, like how toxic mercury is.

There's also the problem of active resistance to vaccine programs from those who think they're an evil conspiracy.

Polio, to give an example, was on the verge of being effectively wiped out, when Muslim fundamentalists started spreading the word that the vaccine was part of a plot (by the US and the UN, no less) to covertly sterilize Muslims and destroy their religion. That's right, the vaccine could tell Muslims from Christians and Jews. Children went unvaccinated and within months the disease popped up again, not only in Nigeria, where this took place, but in Mecca and throughout the Middle East. Yet another example of the scurrilous interference of religion with science and health.

(A possibly even more shocking example of religious fearmongering: a Spanish Cardinal in the Vatican once warned Central American Catholics, some of the poorest and least educated, hence most vulnerable to this type of propaganda, that condoms are made with microscopic holes that actually let the AIDS virus pass through. Presumably he recommended a good prayer for disease prevention instead. It makes me wish I believed in a Hell so this guy could burn in it for a while.)

??????????????

Because the diseases are still around and if we stop vaccinations, they will return in force and kill or maim people. People from places where they don't have vaccines still cause them to be imported into areas where they are considered eradicated.

If we were talking about veterinary science we would call it a "herd health approach" The concern is not for any one individual; CDC Atlanta makes decisions for interest of "the herd" and homo sapiens are social animals

It has to do with the numbers. You're right, if everybody's vaccinated except one kid, he or she's the only one who can get the disease, but the more unvaccinated people there are, the easier things can spread, and everyone will never be vaccinated. There will always be people not vaccinated for various reasons. So to try to eliminate bad diseases, you have to vaccinate as many people as you can.
