The bit I highlighted is irrelevant to RNA vaccines. It's a property of the SARS-CoV-2 RNA which can appropriate the innate cellular mRNA capping system and then use the cellular machinery to replicate itself (FYI, I did my PhD on mRNA cap binding proteins, albeit 20 years ago). The RNA vaccine will in fact use a similar strategy of co-opting the cellular machinery to do its thing, but it's not the same virulent nucleic acid.
You're right to say there may be issues with RNA vaccines since it's completely new technology. Stage 3 testing should hopefully catch if serious side-effects exist. They don't usually approve vaccine with higher than 1:100,000 incidents of serious side-effects since the intent is to give this to healthy people and keep them that way, not make them sick. Given the seriousness of the situation, they may still approve but limit its use in less at risk populations? That said, I'm pretty amazed at how promising the results with the RNA vaccines have been so far in stage 2 and in animals. We may be on the verge of a big technological breakthrough with vaccines if RNA vaccine prove their efficacy and safety.
Awesome, I hope that's the case!
