Similar to the author of the post, I'm surprised that I haven't seen or heard much about bio-hacking your own vaccine. Seems like an interesting trend to follow, though I will be waiting for an FDA-approved vaccine myself.
I am a little worried that https://radvac.org/vaccine/ mentions that their vaccine has "the most extreme complication in some recipients of stuffy noses." I would expect a functioning vaccine to elicit an immune response. I would be more comforted if, like the mRNA vaccine, a sizeable percentage of people trying the DIY vaccine developed a short fever. Though according to them this is expected: "Intranasal delivery of chitosan-based vaccines have shown mild side effects and high levels of efficacy of both mucosal and systemic immunity, when delivered in a prime-boost regimen (in both animal models and human trials).
