Anecdotally;

Most people who take the jab do so out of blind ignorance and fear. I think that if more people could better understand and gain confidence that the therapeutic alternatives work, they would more naturally avoid the jab.

Additionally highlighting the lack of effectiveness of the jabs and necessity of ongoing "boosters" diminish the perceived value of the jab.

There are the facts and then there is emotion. Be attentive to use whichever approach is most effective with the person you are trying to convince.

Good luck.
