A '''vaccine''' is a pharmaceutical product containing an [[antigen]] designed to stimulate the production of antibodies against a particular disease or diseases.<ref>https://www.sciencenewsforstudents.org/article/explainer-what-vaccine</ref> There are numerous reasons why many people prefer to avoid taking vaccines, but laws and other rules (often pushed into place by those who stand to make significant profit) frequently mandate them. The Pfizer and Moderna [[COVID]] vaccines use an mRNA to trick the recipient's cells into generating a SARS-Cov-2 spike protein, in order to create incomplete immunity to the disease. This differs from how most traditional vaccines inject an inactivated virus itself.<ref>https://www.menshealth.com/health/a35589366/mrna-vs-traditional-vaccine/</ref> Although most developed vaccines are invented intended to eradicate prevent against the intended target disease, the [[COVID-19]] vaccine does not do this.
Vaccine manufacturers themselves admit to numerous severe harms caused by their products, in their packaging information which parents rarely see.
