Basically in the States we are getting the message that if you are fully vaccinated you are protected against covid-19 and the various variants. The variants seem to be very contagious with worse impacts than the original. Obviously moreso for the unvaccinated. Are we getting it right that being fully vaccinated protects folks against the delta variants and others?
I hate to be a doomsdayer but it feels like we need more data and more reassurance about how protected we (the vaccinated) are from the variants. This comes at a time when most people are sick of hearing about vaccine issues and vaccine effectiveness and vaccine availability. They just want it to be over. “I got my shot(s) — I am fine.”
How will/do the experts at the CDC inform us as to whether to feel secure in the vaccine’s efficacy with the variants? How and when do they get that data? How and when do we know about the booster availability? Not to mention – what are the larger ethical concerns about vaccinating the world population at large?

I think the CDC and other public health organizations are likely to take the opposite approach and inform the public if the data are showing that vaccines aren’t very effective and action is required to compensate for that rather than coming out with a conclusive statement that they are fully effective, because even if they are fully effective now, that effectiveness could change when new data emerges later on related to a new variant.
Also, mass vaccination campaigns have happened bgeforet, which is why smallpox was eradicated and polio is getting close.
