I have a couple thoughts on that aren't really organized yet.
I had a question of when will Moderna publish their findings. They were supposed to result in June but pushed it back to Q4. I thought of many scenarios that didn't really make sense. If it was good then say it was good. If it is bad then end the trial and stop wasting money. I ultimately did some digging and found the likely reason.
RFS (Recurrence Free Survival = cancer has not come back) for melanoma is measure over a 12 month time interval (Can be longer for other cancers such as 5 years, but melanoma is that bad). I think the last participant enrolled in the trial around late September 2021. Meaning a readout can't occur until atleast 12 months later.
