There are so many myths about the COVID-19 vaccine, I wanted to post some facts about the new vaccines which we can use for debunking purposes. I used to think that the HPV vaccine brought the most hatred and misinformation from the anti-vaccine world, but it’s clear that the new COVID-19 vaccines are their new targets.
This article will only focus on the five vaccines that I believe will eventually receive FDA or European Medicines Agency (EMA) approval – the Pfizer, Moderna, AstraZeneca, Johnson & Johnson (JNJ Janssen), and Novavax vaccines. I remain unconvinced that any vaccine made in China or the Russian Sputnik V vaccine will ever get approved by countries with robust drug regulatory agencies. However, if they are, I will certainly add them to a future iteration of this list.
I’m going to make this in a basic chart form for ease of use. I will link to supporting evidence wherever relevant.

Summary
As you can tell, most of the COVID-19 vaccine facts are supported by science-based evidence. And the myths are unsupported by the evidence.
My plan is to update this easy-to-read list of facts and myths about the COVID-19 vaccines as I run across more nonsense. I intend to always add links that support or refute the claim. I hope that this article is helpful to those of you who are having discussions with people who are on the fence about these vaccines.
