Seeing that well over 99% of vaccinated people never get severely ill -- and severely ill people generate the variants. It is very unlikely that a vaccinated person will generate a variant even if they have health risk factors.
I'll post this from a medical abstract with link below...its about as dumb down as I can find it by researchers in which its very common for people to get drug resistant (very common) mixed up with vaccine resistant (extremely rare).
----------
Why is drug resistance common and vaccine resistance rare?
Drugs and vaccines both impose substantial pressure on pathogen populations to evolve resistance and indeed, drug resistance typically emerges soon after the introduction of a drug. But vaccine resistance has only rarely emerged. Using well-established principles of
population genetics and
evolutionary ecology, we argue that two key differences between vaccines and drugs explain why vaccines have so far proved more robust against evolution than drugs.
- First, vaccines tend to work prophylactically while drugs tend to work therapeutically.
- Second, vaccines tend to induce immune responses against multiple targets on a pathogen while drugs tend to target very few.
Consequently, pathogen populations generate less variation for vaccine resistance than they do for drug resistance, and selection has fewer opportunities to act on that variation. When vaccine resistance has evolved, these generalities have been violated.
With careful forethought, it may be possible to identify vaccines at risk of failure even before they are introduced.

The above brings back the topic of some of the miracle drugs being hyped here
@ Elitetrader.com in which I've asked several questions about why certain countries that have been using these
miracle drugs against Covid infections in 2020 have had these crazy Covid surges in late 2020 and early 2021.
Short Answer - It's because Covid became
drug-resistant to these miracle drugs soon after their introduction into the population of a specific country...resulting in those crazy Covid surges.
These countries then tried to combine the miracle drug with other drugs which by the way is normal even in modern medicine but Covid will soon become drug-resistant to the drug combo. In fact, many use these as clues
(low vaccination rates / high miracle drug use) to anticipate the birth of the next variants.
All of the above will more often than not...birth variants of Covid in comparison to the rarity of Vaccines doing the same.
- Simply, the likelihood of variants was either via not vaccinated people or drug-resistant to a miracle drug and the latter becomes problematic for vaccines to target the new type of variant.
Another way to look at this...research the data about the Covid variants and their
birth locations. They are being formed in countries that had
low vaccination rates at the time of their variant birth but higher use of miracle drugs.
Therefore, variants from vaccinated individuals...
not likely.
In contrast, variants from drug-resistance of miracle drugs
or variants from not vaccinated people...highly likely.
