They were talking about long term protection. Realistically it only needs to last a year or so. After all the flu vaccine is only valid for a year because it evolves so quickly.
As for safety, that's the entire point of these three phases of trials. seeing if its effective is a nice bonus, but in reality to see if there are any problems like there were with the dengue fever jab.
I commented on that part. And yes, it seems to be safe in healthy subjects (Phase I). The OP wants to move from Phase I to production immediately. I take an exception to that approach and I agree with you that there is a point in doing the three phases. The later of which actually focus on effectiveness as well.
Shipping something that's not effective is counterproductive. Being vaccinated would affect people's behaviour, if you told them that they should not change their behaviour back to pre c19, you would be just faced with questions on what's the point of vaccination.
We can ship placebo right now.
