Yes, you need to show that the new vaccine works against the new variant but not that it’s safe. So it will be much faster

- refurb 5y agoWhy would you not need to show it’s safe? A new mRNA vaccine would be introducing different mRNA, which produces new antigen proteins and elicits a different immune response.
- johnchristopher 5y agoIf it elicited the same immune response it wouldn't be much of a use though, right ? Anyway, how do they know the usual but new seasonal flu vaccine is safe ? Can't the same framework apply ?
- refurb 5y agoThey run clinical trials on them to make sure they are safe and effective. https://www.cdc.gov/flu/vaccines-work/effectivenessqa.htm https://www.cdc.gov/flu/vaccines-work/effectivenessqa.htm Manufacturers guess which flu strain will predominate and start working 9-12 months early to capture the data for approval. There is no way a new Covid mRNA vaccine will be approved with safety and efficacy data from a clinical trial. That will be take months to complete.
- ed_balls 5y agoIt's possible that mRNA would reduce the time to the market, which would give use more time to gather data and have better predictions of dominant strains.
- tempestn 5y ago> There is no way a new Covid mRNA vaccine will be approved with safety and efficacy data from a clinical trial. You meant 'without', right?
- pbaka 5y agotbf to OC, I think he got it right ;-) /s
- johnchristopher 5y agoWow, thanks. I didn't know that they had an extensive clinical trial program and that the whole thing started so soon.
- weaksauce 5y agoYeah i'm pretty pro vaccine but it seems like safety should be evaluated because it's creating a different antigen. maybe this is some relic from the flu-shots being made yearly without any real safety testing to my knowlege(which, to be fair for the flu, I haven't really followed so i don't know how accurate that is but i don't think much meaningful safety testing can be done every year)
- ralusek 5y agoYou would think software engineers would understand this. It's like approving subsequent pull requests on any and all code changes because the integration tests already passed once.
- nojito 5y agoThey still need to do Phase 2...I don't where you got your info from, but it's very misleading.
