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 intended to 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.

Vaccine manufacturers themselves report some side effects caused by their products, however these are minor.

==Influenza Vaccine==

The flu vaccine is an example of modern vaccination. Due to the change in [[allele]] frequency over time in the population of the influenza virus, new influenza vaccines are created each year.  In some years the vaccines are less effective than in other years. According to the CDC,"Influenza viruses are always changing. Therefore, influenza vaccines are updated every year, and annual vaccination is recommended".<ref> "Inactivated Influenza Vaccine, What you need to know," a publication of the Center for Disease Control, 2006.
