This is also true of the AstraZeneca and Pfizer candidates. The hard bit is showing that they work. I’m always surprised how often R&D is discussed with more emphasis on the R and than on the D.
One of the most insane details of our current ordeal is that the Moderna vaccine was actually designed in two days.
In January.

AstraZeneca’s supply deals for the developing world seem better than those of Moderna and Pfizer, in terms of quantity and price. And it's more thermostable too.
Of course, we won't know how long lasting these vaccines are until much later. But it's heartening that there are other vaccine approaches ongoing that don't focus only on the spike protein. Hopefully their incentives to continue pursuing these are still maintained.
Great to see Moderna's interim results today, even if they were somewhat expected following last week's news. Particularly noteworthy is that the severe cases were all in the non-vaccinated arm of the trial. Didn't have much info on that from Pfizer's trial design.
Together, Moderna and Pfizer results bode well for the the Astrazenca trial too, since they all target the same spike protein. It will be really good to have multiple suppliers, and more thermostable options on the table.
Yes, interim efficacy data so far hinges on 94 infection cases, of which v few were in the vaccine arm (to claim 90% efficacy, would need to have been less than 9). To find those 94 infection cases, the overall trial participants much larger: 44,000.
@Nightingale_P Doesn't last long once vial is opened, need to schedule appointments carefully to reduce waste. Will likely need more than one dose. Huge variation in logistics capabilities across countries, cf @BiotechPolicyUK et al Test n Trace study.
Very encouraging *interim* phase 3 vaccine results. It would be a major landmark for mRNA vaccines. Worth bearing in mind that it would be one of the least thermostable vaccines of the possible potential options, making deployment much trickier, esp in developing countries.
You may want a different type of vaccine that is easier to deploy, but wide scale deployment of this vaccine, could make evaluating other, potentially more thermostable, vaccines trickier.
Preliminary data analysis of the first #Covid19 vaccine Phase 3 trial provides very good news about the Pfizer-BioNtech mRNA vaccine. Vaccine looks to be quite efficacious, @matthewherper reports. https://t.co/AM90BDMXIP
Understanding these features will be useful for comparing vaccines, as vaccines may have different strengths and weaknesses. Thanks again to @mlipsitch. We hope this stimulates some useful discussion on how to generate broader evidence to inform strategic decisions. 5/5
