That is a moral question I consider to be separate from whether getting vaccinated is a personal choice. I personally don't think the government has a place in either, but I don't demand that others believe as I do.
We know how to keep from becoming infected - stay away from people. For most people, this is not an option or at least not an option they choose to employ. If a person chooses not to isolate themselves because they are at high risk, what else can they do? Are they doing everything in their control to make sure they don't become infected? Do they wear an N-95 mask? Do they have their groceries delivered? I'm just making the point if a person is at high risk, they have to accept the responsibility of protecting themselves. It may not seem fair, but it is what it is.
Is it my responsibility to get vaccinated just on the chance I might become infected and might infect someone who for medical reasons was unable to be vaccinated or is immuno-compromised? Leaving morality out of it, it seems to me that the person who is immune-compromised has the responsibility to protect themselves. I believe someone who has received a transplant, gets almost no protection from the vaccine.
These are the people who should be exploring options like Ivermectin. Studies seem to indicate Vitamin D levels are also very important. The FLCCC has a preventative protocol that people can follow. Are they following the protocol?
My point is as good citizens, we all have a role to play, but the very highest priority is what the individual can do to protect themselves. Then what the parents can do to protect the family.
As I posted earlier, I did get vaccinated, but the more I learn about the vaccines, the more I think I made a mistake, even personally being at high risk.
Based on my research, I take Ivermectin weekly because I believe if I do get exposed to the Sars-cov2 virus, it will likely destroy it before it becomes Covid-19. I also take daily vitamin d, vitamin c, b-complex, zinc, and quercetin, and at the 1st sign of any sniffles, I take elderberry extract (natural antiviral). I rarely get a cold or the flu, so it seems my immune system is pretty good at fighting off viruses already, but now it is as primed as I can get it.
I have been encouraging people who are not getting vaccinated to take Ivermectin weekly as a prophylactic. I know some are deciding to just have it on hand to take at the first sign of infection.
I don't know why people see the Covid-19 vaccines in such polarized ways. I probably spend at least 2 hours a day reading updates from Israel and Britain, looking at US stats, listening to podcasts by doctors who are treating Covid-19, and trying to understand why over 1 1/2 years after Covid-19 was discovered, the US government still does not have an early treatment protocol for Covid-19.
I would suggest you refer your daughter and son-in-law to the FLCCC site for their I-Mask+ Protocol for prevention.

It's strange how differently people see things. If I was to get Covid-19 and become hospitalized, I don't think it would ever occur to me to blame someone who hadn't gotten vaccinated. I would be wondering what else I could have done to protect myself. Did I take unnecessary risks? If someone close to me became very ill, I would blame myself for not doing enough to protect them.
