The Chicago Sun Times reports that in a disturbing California Bay Area trend, parents wary of vaccinating their kids are considering having their unvaccinated children attend measles parties with those who are infected. The idea is the same as a chicken pox party. Parents bring their children to these gatherings to get them sick once so they won’t have to deal with the virus again. Except, most cases of chicken pox aren’t deadly. Marin County Public Health Officer Matt Willis says that although his office has received no reports of such parties, officials have fielded several calls from parents asking about the benefits of "natural immunity," or the idea that immunity gained from contracting a disease is superior to immunity conferred through vaccination. Measles is a serious illness that can cause brain swelling, long-term neurological effects and even death, Willis says. Plus, he added, there is no evidence that immunity gained through becoming sick with measles is any better than vaccine-imparted immunity. "Any parents who are considering this, they should have a look at a child who’s really sick with measles, and I think they’d change their minds."
Willis and other health officials suspect the concept of a measles party may have grown out of "pox parties," which were popular in the 1980s, before the chickenpox vaccine was widely available. Some parents, reports said, even arranged to pay strangers for licked lollipops, saliva or other items from infected children. Willis says he still hears reports of “pox parties” occurring in Marin today, even though a chickenpox vaccine has been available for more than two decades. "It was not a good idea then, and it's still not a good idea," says Wilbert Mason.

Vaccines for polio, mumps,, measles, rubella , yellow feaver, confer life-long immunity.
There are several more which are suspected of life long immunity simply because they are too new to be sure or there are no re-infections known.

WHO recently added yellow fever to the list.
