So happens that Israel has a very high percentage of vaccinated people.
Results are not pretty at all.
...Considering only COVID19-associated increased risks during the 5-week vaccination period, vaccine-induced protection would need to be absolute, which it is not, and last much longer than the 12 months projected until the next vaccine injection is required. Including in calculations unavailable precise data on vaccine-induced increased risks unrelated to COVID19 will necessarily increase the vaccine protection period required to compensate for all vaccine-associated deaths, probably beyond 2.5 years.
Our calculations for younger age groups predict an even more extreme and dire situation. It is long known that vaccination is not cost-effective against organisms or viruses with highly mutable genomes. RNA viruses, coronaviruses and HIV included, have the most mutable known genomes. Note that vaccine-associated risks increase proportionally to the strength of the immune system, predicting that vaccination will greatly increase the very low COVID19 risks experienced by the younger population. Extrapolations two independent available datasets confirm this prediction. The precautionary principle is the first priority of those responsible for public health and its urgent application is required at this point, especially when the whole population of a country, including its youth, is at stake....--America's Frontline Doctors quoted at Vox

For a study of cost-benefit analysis (the Vax is a loser there, too) its conclusions as to risk to under-70's is rather chilling.
