I'm not religious -- very far from it. But I do consider myself a humanist, and I live my life according to the precepts of humanism (as I understand them). In particular:
"The social system is interwoven with our human nature. We need to relate to others in order to lead our lives, profit from our capabilities, and be happy. Society is nothing but a necessary, beneficial and even vital agreement between everyone. An agreement not imposing arbitrary constraints on us, but protecting all from abuse, and providing for the well-being, and development, and the most fruitful life of all of its members.
It is a magnificent reality that each of us is a fabulous organism, with possibilities that seem boundless. Knowing how much we are worth, knowing how important each one of us is to all the rest, and all the rest to each of us, knowing we are both nature and nurture, knowing our reciprocal dependence on the rest of nature, seeing that all the other people know such vital facts, and using our capacity to solve problems by understanding them, we will improve on the way all of us lead our lives, and we will reach--as individuals, as nations, and as a species--superlative levels of well-being."
Therefore, I get the vaccine - and therefore I would strongly, strongly urge others to, as well.
