As soon as Dr. Jenner developed the first smallpox vaccine, religious fanatics went all out to discredit him and to claim that vaccines go against God's plan. According to this website, religion-based anti-vaxxers were busy even before Dr. Jenner's seminal work.

“As soon as Dr. Jenner developed the first smallpox vaccine, religious fanatics went all out to discredit him and to claim that vaccines go against God’s plan. “
That seems a bit of hyperbole, based on the link you referenced.
Still, it is amazing how today’s anti-vax stance is a diabolically clever mix of religious-type concerns and leftist ones, e.g. it’s not natural and it is evil corporations trying to make money.
