I feel for your situation and echo others here that this is a red flag for the relationship, but I also would agree with some posters that you should try to better understand the motivations behind his actions. Whatever the situation, in some ways you're stuck with him and the legal system is a nightmare (and our position on the covid vax is not held by TPTB!)

On the topic of vax shedding, based on my research, it is likely not a problem in most cases. There are anecdotal reports of people observing issues that appeared to be caused by shedding, and I believe that it probably does happen for some people. But there is also strong evidence that it does not typically happen.

Part of what makes these shots hard to understand is that by their nature, the effects vary widely across the population and also based on chance. Because the nanoparticles can invade literally any cell in the body that they contact, the "attack surface" of this vector is extremely broad. This is one thing that makes its behavior completely different from a real SARS-Cov infection: the real virus only attacks cells with ACE2 receptors.

Next problem is that while the injection is supposed to "mostly" stay at the injection site, it doesn't, and the amount that makes it to the bloodstream is totally down to chance, and possibly the skill of the person giving the shot.

So, the material that gets in the bloodstream, goes everywhere, and can hijack any cell in the body. My theory is that some cell types, in some people, react differently to the mRNA and instead of using the mRNA template once to construct a spike and "display" it on the cell membrane like they are supposed to, somehow they just sit there churning out spike proteins into the bloodstream.

Churning out spikes could definitely lead to shedding and probably a lot of other problems.

HOWEVER, if you look at this paper (the relevant info is in the 'supplementary materials') it seems that this is not typical.

https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciab465/6279075

This paper took 13 subjects who were given the Moderna shots, and measured the level of spikes in their blood over time. It showed that most of the subjects had measurable quantities of the protein in their blood at some point, but it was more like a 'blip' than a constant level. It also showed considerable variation among subjects in this regard.

Bottom line - there's a lot of variation in response, but in 13 subjects none of them showed consistent levels that would be needed to "shed". However - it's only 13 people. 1% of people could have a totally different response and this study would miss it. But it suggests that your fiance is very likely not shedding. In my personal experience I haven't encountered problems being around vaxxed people (where I live almost everyone is, including my parents, sadly, and I have spent a lot of time with them indoors, etc.). Some people have, and I don't disbelieve it - I think maybe it is just fairly rare.

That said, you definitely want to wait a couple months because the data in that paper did show measurable levels at various points in time up to a few weeks post shot 2. Note this is for Moderna and I don't know how the other shots behave. And I would not fault you for waiting until after weaning because nobody really knows. I guess I would just say that there's some evidence that it's not as bad as some people believe.

The saddest thing about this story is that the rise of the delta variant makes the vax discussion moot. Delta is rapidly outcompeting the other variants and is much more mild.. and the vax doesn't work on it anyway except to stop symptoms in milder cases. So at this point it's literally 100% risk and no reward!

I hope you can keep your son from doing this. If you are looking for more source material, I found this site useful (here is a discussion of the risk/reward for vaxxing young people)
