My impulse is that you’re trading one thing where the long term side effects are not 100% known (mrna vaccine) for two things where the long term side effects are not 100% known (covid and the mrna vaccine), and that there’s substantially more reason to believe long covid is a thing than that there are long term side effects to the vaccine. Bigger issue though is that there’s no way to know exactly how long natural immunity will be effective either, as we know it also can wane in regards to this coronavirus. Giving a child covid now may be pointless to the goal of giving stronger protection to a more problematic strain later, if the strain comes along after the natural immunity has faded. Realistically though, given current stats, the only statically valid reason to get babies vaccinated is to help lower community spread. Whether that’s asking a baby to “take one for the team” or reasonable depends on how much of a risk you view the vaccine as to children given the current data. (My personal belief is that long covid is a marginally higher risk than vaccine side effects so there’s no reason not to also lower community spread, but there’s no reason to think the baby won’t be fine either way).
