What exactly is "the desired effect?" If it is to eliminate Covid, the vaccine doesn't seem to help much, considering vaccinated people can still get infected and pass on the infection to others.
The desired effect of the mandate is to increase the percentage of the workforce that is vaccinated. It appears to be achieving that goal.
As has been mentioned many times on this thread and others, unvaccinated people are at least 5X more likely to contract and transmit COVID-19 to others.
Your numbers are way off. I encourage everyone to get vaccinated if they can. But the reduction in risk of transmission is far more limited and temporary than you claim.
> Unfortunately, the vaccine’s beneficial effect on Delta transmission waned to almost negligible levels over time. In people infected 2 weeks after receiving the vaccine developed by the University of Oxford and AstraZeneca, both in the UK, the chance that an unvaccinated close contact would test positive was 57%, but 3 months later, that chance rose to 67%. The latter figure is on par with the likelihood that an unvaccinated person will spread the virus.
> A reduction was also observed in people vaccinated with the jab made by US company Pfizer and German firm BioNTech. The risk of spreading the Delta infection soon after vaccination with that jab was 42%, but increased to 58% with time.
