No, I correct them.
"The smallpox vaccine for example killed more kids than the disease did."
Smallpox killed 500 million people in the 100 years prior to it being eradicated by a mass vaccination program. The vaccine did not kill millions of anyone, let alone children.
"nothing good comes from using aborted babies in the development of these vaccines."
Agreed. Thankfully, every vaccine except Hepatitis A and Rubella have ethically sourced alternatives. For SARS-CoV-2, many vaccine candidates have zero development using fetal stem cells, including two (GSK's candidate and Novavax's candidate) backed by the Trump administration with billions of Federal tax dollars invested.
The data doesn’t add up to your claims, however, you are free to do as you will. The flip side of that is so an I. Nobody attempt to force this on me and I won’t care.
