Wouldn’t the answer to each of those questions be:
There is no FDA tested and approved Covid vaccine formula available at this time.
My answers (yours May differ):
1) It is the first vaccine that I am able to decline; all others were given me when I was a baby/child, where I had no say in the matter.
2)Yes. The head of my church is God /Jesus Christ/Holy Spirit, and He says in His Word the Bible, in Romans chapter 14 (especially in verses 22 & 23) not to violate my conscience; to take the vaccine violates my conscience.
As a Christian, I have the Holy Spirit within me, and therefore per His Word in 1 Cor 6:19 my body is a temple. I do not disagree with His Word.
3) Being a Christian, I have been saved by grace, and thus am an active Christian, and do not harm my body, the temple that God has given me.
4) I do not smoke, drink excessively, or use illicit drugs.
5) I don’t smoke, only drink a tiny thimble cup of communion wine once a month, and might take some medically necessary medications. Since I have a choice to take or not take the vaccine, and the vaccines contain mRNA, I do not choose to damage my body, the temple of the Spirit, by introducing mRNA into it.
6) I read my Bible, God’s word, and the context for not choosing the vaccine is that I follow God’s commands in Romans chapter 14 (especially in verses 22 & 23) and 1 Cor 6:19.
