About VaxCalc

Christopher Downey is the founder and visionary behind VaxCalc, the first and only service that provides a structured process, compassionate support, and an online community for informed vaccination decision-making. VaxCalc expresses Chris’s dream of creating a powerful force for good in the world by overcoming censorship, strengthening and spreading freedom, and creating community.

Chris is a noted full-stack software developer, open-source contributor, published vaccine safety researcher, Internet-boom bootstrapper, cryptoassets investor, and founder of the largest DevSecOps (modern software development for national security) meetup group in the United States.

A two-decade veteran vaccine-freedom advocate, Chris has fought long and hard to protect his children from excessive vaccination and the one-size-fits-all thinking that afflicts many pediatricians today. In 2016, he fought successfully to protect and preserve Virginia's religious exemption.

Philosophically, VaxCalc is rooted in American Revolutionary thought encapsulated in an 1822 letter from James Madison: “Knowledge will forever govern ignorance; and a people who mean to be their own governors must arm themselves with the power which knowledge gives.”

Chris continues to be astonished by Matthew 9:13: “But go and learn what this means: 'I desire mercy, not sacrifice.'” To learn more about Chris's unexpected faith journey, listen to his personal interview on Real Faith Stories.
