The vaccination principle has given rise to different terminologies used to identify how good a vaccine is, or how harmful a vaccine is to us. For the latter definition, the term antivaxxer day by day has become a stronger word that attracts every one of us. In particular, it become more popular during the COVID-19 pandemic era. On the other side, those who are pro vaccination too, have their own well organized fighters, mainly: members of the Big Pharma industry, their affiliated social media, as well as some journals. Certainly, such highly polarized two groups at the end of the day should move us to common consensus! Unless, if without science-based agreements/justifications one of them wins, the vaccination issues may lead us into chaos chaos that is flowering today! Moreover, what will be worse is - such tendency will transmitted to medication too. This is why in our results of a three-year (2021-2024) intensive study on Are intramuscularly injectable vaccines feasible to stop respiratory-based pathogens? except experimental-clinical case studies-metadata, we have been forced to collect data on the three meanings as well as their impacts. We analyzed, politicians speeches, Social Media posts, vaccines developers positions, and of course antivaxers rhetoric-movements. We postulate that to minimize speculations within vaccination principles and medications as well, the mentioned differences should be categorized with clear definitions by relevant stakeholders. If not, neglecting the child vaccination, autism, etc., at least in future pandemic, there will be more worsening messes, chaos, and even deadly conflicts than in the COVID-19 era! About which, we will brief in the conferences event.
