I don't know if Jesus made vaccines or not. If you have clear evidence one wy or another, I'd like to see it.
Other than that, Jesus forgives even you,
franky1. Not believing in Jesus is a sin against the Holy Spirit, and sins against the Holy Spirit will never be forgiven.
Is it your magnetic side that keeps you from believing? Mesmerism towards evil.

... I don't mean to be obtuse dude, but no one "understands" God. That is the entire underlying Biblical theme of
FAITH and
HUMILITY. More than anything humility and calm acceptance of inferiority is promoted in Holy Spirit inspired works.
Yes Jesus sent the Holy Spirit to dwell within us all, and that is a spiritual connection with the Great One and Jesus, but (I have not completed NT yet) from what I know that is focused on discernment and building the connection with the Godhead not arrogance about the Godhead's perceived actions.
Humility and
Faith.
