What Does It Signify When A Christian Willingly Has The Covid-19 "Jab"?

A question I have currently - what does it signify when a Christian is willingly having the experimental “jab” and is I can presume happy with all the planned rollouts of “passports” to show you have had the jab, when we know as Christians what it says in Revelation 13 16:17...

“And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.” ‭‭Revelation‬ ‭13:16-17‬ ‭KJV‬‬
