If nitrous oxide as a means of sedation is gassing I am not opposed.
You need to be specific.
You seem to be intentionally vague.
My point is that the term "vaccine" is intentionally vague, and only becomes specific when the actual content and conditions of a specific vaccine used for a specific purpose towards a specific population in a specific way is addressed.
However, as you don't seem to want to acknowledge that simple, obvious point, and as I have no interest in your agreement, it seems we're done here.
