Re: Vaccine skepticism: A problem fueled by ubiquitous data and rarefied understanding
<i>AZ is a viral vector: a more established approach to vaccine creation.
Specifically it's a chimp cold virus, modified to resemble Covid-19, without the nasty bits. This is a well established approach to vaccine development.</i>
This isn't quite right. Viral vector vaccines are novel and there have been just six approved for use in humans - four for COVID and two for Ebola. The first, rVSV-ZEBOV, for Ebola was cleared in November 2019.

<i>mRNA has been approved before, just not for something on this scale. It's just that people haven't heard of it before which has caused hesitancy.</i>
Again, this is incorrect. Research and trials on mRNA vaccines have been going on for 30 years but the Pfizer-BioNTech COVID vaccine was the very first to be approved.
