The current issue is not whether an individual ought or ought not to get immunized for their own sake. The effectiveness of the immunizations in mitigating the severity of COVID WHEN you get it is pretty easy to show.
The issue of THIS thread is whether it ought to be MANDATED by an employer for the purpose of protecting pax and other employees. It would appear there is little evidence to suggest that is effective, since vaccinated can STILL contract and SPREAD the virus.
From the Lancet:

To address the primary study outcome to establish the secondary attack rates (SARs) in household contacts, the vaccination statuses for 232 contacts exposed to 162 epidemiologically linked delta-variant-infected index cases were analysed. The SARs in household contacts exposed to the delta variant was 25% in vaccinated and 38% in unvaccinated contacts. These results underpin the key message that vaccinated contacts are better protected than the unvaccinated. All breakthrough infections were mild, and no hospitalisations and deaths were observed. But these results also highlight that breakthrough infections continue to occur in the vaccinated, with an attack rate of 25%. Time since vaccination in fully vaccination contacts was longer for those infected than those uninfected, suggesting that waning of protection might have occurred over time, although teasing out general waning versus reduced vaccine effectiveness due to delta is challenging owing to so many confounding factors.
SAR among household contacts exposed to fully vaccinated index cases (25%; 95% CI 15–35) was similar to household contacts exposed to unvaccinated index cases (23%; 15–31). Obviously, infection might also have occurred beyond the household level with unknown exposure in the community. Indeed, genomic and virological analysis confirmed only three index-contact pairs. Owing to the small sample size, the authors were not able to establish the vaccine effectiveness against asymptomatic infections versus symptomatic infections. This limitation together with the unconfirmed source of transmission in many of these index-contact pairs, suggests that the low SAR reported here should be interpreted with caution. Nevertheless, the findings raise concern that the effect of vaccination on reducing transmission might be lower for the delta variant compared with the variants that circulated in the UK before the emergence of delta.
