I'm just a layman, but the article seems to support the assertions in the letter.
From the NBC story:
People under 60 are accounting for the majority of new Covid-19 cases across the country — likely a testament to the success of the vaccines that have been administered to primarily older, more vulnerable Americans... doctors say that patients seeking care this time around are younger and, notably, not as sick..."The cases we are seeing are the younger groups that probably aren't eligible for vaccines just yet," Davis said...
Nationwide, "the number of 25-to-49-year-olds visiting U.S. emergency departments for diagnosed Covid-19 is now higher than the number of visits among patients 65 and older," the CDC said in a statement to NBC News...
The virus itself, however, is shifting and changing. "We know that about 26 percent of all sequenced virus is now the B.1.1.7" variant, Walensky said during Monday's briefing. That variant has been shown to be more contagious...
"The good news with the variants is, they are all mostly responsive to vaccinations," said Dr. James McDeavitt, senior vice president and dean of clinical affairs at Baylor College of Medicine in Houston.
The doctor said in his letter that the virus would "escape" and attack a different segment of the population. He also said that it would mutate, and that the mutation would be stronger.
Doesn't the NBC story confirm this, even if the article also says that the variants are "mostly responsive" to vaccinations?
Can't the Doctor's warnings also be true even if the current vaccinations are also effective?

The good doctor’s solution is to stop all vaccinations except those based upon his preferred solution. Doesn’t that seem strange, what we’re doing is working so we should stop?
