What is the risk of asking my bank to delay getting vaccinated until Pfizer gets full FDA approval?

I want to stress that I am not trying to avoid getting the vaccine. My bank requires everyone to be fully vaccinated by the September return. This means I would need to get my first shot next week. I have been reading up on vaccine efficacy, risks, and the differences between EUA and full approval. I genuinely feel that a more detailed review and availability of longer-term data (6 months for full approval vs 2 months for EUA) would make me much more comfortable with getting the vaccine. With Pfizer likely getting approved by September, I feel like it's a reasonable ask. 

Obviously I would need to speak with the head of my group and with HR. I don't anticipate pushback from my group, but what are the risks of asking HR to delay getting vaccinated? I would assume if they agree, they would ask me to work from home until I get vaccinated. Seems like this would be a few weeks to a month at most if the Pfizer vaccine gets approved later this month. But would this be enough of a cause for termination/unpaid leave or getting put on a shortlist to be let go? I do feel pretty strongly about waiting, but if just stirring this pot could get me in serious trouble, I'd rather not even bring it up. 

Would appreciate your advice, especially if any of you have similar concerns or work in HR.
