We know nothing about the long term effects of this vaccine, or how it will affect our bodies when it comes to dependencies. I understand that millions have taken it, but that still doesn't show me any long term tests.
So I'm selfish because I want to protect myself and my family from something that I don't trust? I'm not anti-vax - we have all our shots. If after say 5 years, it turns out that there are no long term side effects, then I'm fine taking the vaccine.
