The health issue is that Covid results in severe symptoms that will see a number of people hospitalised, in ICU, or dead. Vaccines reduce the likelihood of infection, and if infected, reduce the incidence of severe symptoms. This is the point of vaccines, as well as helping slow the spread of disease. Basic public health measures (masks, distancing, sanitation practices) are likely to be more effective to slow spread, though best is both.
Mutation happens naturally, and the more people with Covid, the more mutation occurs. At the moment, with large populations of unvaccinated, there is likely to be a lot more people in those populations getting Covid, so that will be the source of most mutations. Vaccines do not cause mutation. As you say, there are tens of thousands of mutations. It is what allows people to determine where a virus comes from. Most of the mutations are insignificant. Only a few are "variants of interest" or "variants of concern". That's why we can say a virus is Delta, but with minor variations that say it came from the UK vs the US west coast. The named ones, the "variants of concern" are the ones that may become dominant.
At the moment, contagiousness is the main determinant of viral dominance. That's why Delta is the main viral strain found everywhere. As most of the world develops antibodies (through vaccine or surviving infection), ability to evade immune reaction will become more important in making a strain dominant. This is the case whether the immune response is from vaccine or infection. Exposure to the virus is more likely to create a robust immune response. But vaccinated people will also be exposed, as the virus spreads. This will result in increased immune response.
Ultimately, there will be shifts in our antibodies, as the virus changes. Vaccines will become less effective, and new vaccine variations will be needed, as with flu virus. But the point of vaccines will be to reduce symptoms, as with rotovirus. This will mean hospitals are not overwhelmed, and potentially, that there will be few people (not no people) becoming seriously ill or dying of Covid.
You probably know this, so this is for others.

You spew a lot of what the MSM is dishing out. You must not have talked to any medical professionals who have been silenced. You might try doing so.
