This seems to go against that general consensus here but fear of what can harm us is even more harmful. Fear is evidence we are not living is God's spirit

Mark 16:18 18 they will pick up snakes with their hands, and whatever poison they drink will not harm them; they will place their hands on the sick and they will be well.” God gives supernatural protection.

Matthew 10:26 “Do not be afraid of them, for nothing is hidden that will not be revealed, and nothing is secret that will not be made known. 27 What I say to you in the dark, tell in the light, and what is whispered in your ear,[d] proclaim from the housetops. 28 Do not be afraid of those who kill the body[g] but cannot kill the soul. Instead, fear the one who is able to destroy both soul and body in hell. Man can do nothing to our bodies.

it is our mind and soul the enemy wants. It is right to pray for healing for those who have taken a dangerous vaccine. Pray that they will be healed but also pray for those who relize they have made a mistake for peace and not to have fear.
