It was 50% effective, not 50% of population vaccinated

Experts have been consistently pushing for 85%+ to get vaccinated to reduce the number of potential vectors as well as reservoirs.

Delta is at least 4x more infectious than alpha, and it children were much more susceptible to infection. Those under 12 appear to be reservoirs for the virus and until they are vaccinated at large number we will see continued spikes.
