> What's the catch? Is it significantly riskier than the Pfizer or Moderna vaccines? Is it easy to make a mistake while producing this and end up with something ineffective or harmful? Is it just not particularly effective? Yes, yes and yes. This is all good fun, but isn't a super novel vaccine. The vaccines that are currently being delivered were mostly developed within weeks of Chinese researchers sharing the genome sequences in January 2020. The bits that took the time were the safety and efficacy trials, which is what this is skipping. And it's not like $1000 for a household is cheap: the Oxford/AZ vaccine costs about $3.
