ελληνικά / Deutsch / Português Welcome! In this post, we’ll be taking a character-by-character look at the source code of the BioNTech/Pfizer SARS-CoV-2 mRNA vaccine. I want to thank the large cast of people who spent time previewing this article for legibility and correctness. All mistakes remain mine though, but I would love to hear about them quickly at bert@hubertnet.nl or @PowerDNS_Bert Now, these words may be somewhat jarring - the vaccine is a liquid that gets injected in your arm.
