Vanessa, it's not anyone's business until you proclaim it in a public space.  So here's some facts to think about.  Your decision is still yours...

In Great Britain, a drop in pertussis vaccination in 1974 was followed by an epidemic of more than 100,000 cases of pertussis and 36 deaths by 1978. In Japan, around the same time, a drop in vaccination rates from 70% to 20%-40% led to a jump in pertussis from 393 cases and no deaths in 1974 to 13,000 cases and 41 deaths in 1979. In Sweden, the annual incidence rate of pertussis per 100,000 children 0-6 years of age increased from 700 cases in 1981 to 3,200 in 1985.

They were also really healthy kids too... Until they dropped dead. Really dead.

Shall we turn into another Nigeria, where hundreds of people died in the early 2000's when they withdrew vaccinations? http://www.ncbi.nlm.nih.gov/pubmed/18690921

Yep. Healthy right up until the day they died.

In an outbreak of 25 cases of measles in Qld in Q1 2009, NONE of the cases were vaccinated. Also, referring to another outbreak, “The number of vaccine doses was known for 57 of the 78 cases, of which none had received 2 doses of a MCV, four (7%) had received 1 dose and 53 (93%) had received no doses: the remaining 21 cases were of unknown vaccination status”

During an outbreak in Q2 2006 in NSW, of the 33 children with measles, only 6 had received 1 dose of MMR, and the others none. None of the cases had received two doses.

ie: non- and under-vaccinated children get diseases.

And if we're talking risks vs benefits...

Good luck.
