GMOs are economically a good thing, given that full disclosure is required. The science isn't settled on every GMO, but on some of them it is. Approach each individual GMO differently. Golden Rice is a good one.
Vaccines are on average going to help more people than they harm, but there are side effects for a reason. They're not always entirely safe, but they're still a good thing.
For every claim I am aware of in support of GMOs and vaccines, there are extensive rebuttals and science to back them up that most appear to have never encountered. Specifics are needed for such statements to hold weight.
