I wish it was so simple as "if you don't want them, don't get them" - but some state governments in the USA (California, West Virginia are "medical exemption" only, which are hard to come by even if you can prove vaccine injury) and international governments (France, Italy) are mandating them in order for children to be allowed an education.
So, no, it isn't a simply "just don't get them if you don't want them" choice. Governments worldwide are mandating them, to the financial benefit of the companies that manufacture them. Follow the money...who is receiving money from the manufacturers to push the legislation?
There is increasing evidence that vaccines are NOT safe for some - and there is not testing for children before injecting them with vaccines to determine if they are not a genetically compatible individual for vaccines.
Additionally, Vaccines and Autoimmunity, a medical textbook published by well-known textbook publisher Wiley, lists numerous studies finding compelling potential links between certain vaccines and certain autoimmune disorders. http://www.wiley.com/WileyCDA/WileyTitle/productCd-1118663438.html
Personally, I'd rather my child have a week of chickenpox, than a lifelong autoimmune disorder like rheumatoid arthritis.
