Which was the general overall historical approach to vaccines, specifically childhood vaccines. I haven’t been shy about saying we don’t know something things about this vaccine. One of those being if this vaccine can reduce transmission. We don’t know definitively because that answer takes years. But historically speaking, when considering how viruses replicate and operate one could reasonably suspect that if the virus is being beaten back by the immune system it won’t create a viral load large enough to be transmissible. But that is theory and conjecture. We don’t know if historical precedent will hold in this new vaccine.

It takes years to get that information.

Again the post you were responding to was a general, historical approach to vaccination and specifically mentioned childhood vaccinations.
