Looking at what was posted yesterday. That’s the point. Parents like you will simply wait for the final data. They expect that. Based on the low uptake of the 5-11 shot, they expect the vast majority of parents won’t get their kids vaccinated at all. However, there is a small percentage of parents that will not commit to what you and everyone else wants… learning to live with Covid… until their kids can be vaccinated. And this group is willing to get a jump start on the vaccination schedule.
The families with someone immunocompromised, the families of front line workers in public health, healthcare, teachers and other professions that want either vaccine availability or mitigation. Since everyone else has decided no more mitigation, they are making the vaccine available to those who would choose it.
There are two elements in the vaccine trials. Safety and efficacy. They are confident from the first study and additional data out of Europe where they have vaccinated young kids, that they have satisfied safety concerns. The lay people that are nervous that a third dose might reveal some safety concern the first two didn’t were unlikely to get their child vaccinated right away anyway. So then that leaves VE and the risk of needing additional, reformulated shots later. But since this group is expected to be small, and from the super pro-vax group they will get those shots for their kids too. There is the risk of harming confidence, but pragmatically… that ship sailed.
If 5-11 uptake showed improvement over time they might not take this calculated risk. Given how poor that rate is they have decided there is more to be gained by satisfying the parents who have concerns about their unvaccinated kids being in a world without mitigation. Other parents have already decided to accept the risk of Covid infection for their kids. There is no expected path where delaying the former’s jump start results in the latter vaccinating their kids in significantly increased numbers. This is what “living with Covid” looks like.
If you are uncomfortable, than you just wait for the full data.
Edit to add: allowing parents the choice to jump start, effectively makes it function as an expanded trial. The parents with kids in the trial knew the risks that from a VE perspective the vaccine might not work, and that was okay by society's standards. Now they are giving more parents that choice given we are swiftly moving to no mitigation.
