“breakthrough infection is rare”

Or. Does the vaccine GIVE you the illness. No. Not that...

The "vaccines" don't work against the variants, and recently injected are especially at risk because their immune system is also learning to fight the mRNA as well:

For an individual who has just received the first dose of vaccine, his or her body will be in the process of building an immune response. It could take several weeks for the immune response to be fully developed and if you are exposed to the virus during this time, your immune response may be too weak to effectively fight the virus. Even though the first dose may protect you from developing symptoms, the virus may still be able to replicate and transmit. Exerting high immune pressure without preventing viral replication and transmission is a recipe for selective viral immune escape. However, what we are now more and more observing is even more worrisome: even those who got fully vaccinated before exposure to Covid-19 are no longer controlling virus replication and transmission. This is because they’re now increasingly infected by more infectious variants, the spike protein of which is different from the one comprised in the vaccine. Hence, the virus increasingly evades the vaccinal antibody response. We have already seen this in many care homes where highly infectious variants have been spreading within no time despite large vaccine coverage rates (i.e., up to 80-90%). The only benefit of these vaccines is that they may temporarily protect from severe disease and mortality (depending on the antigenic features of the infecting variant).
