Only if you have a very high deployment rate.
A deployment rate that equals distributed shots to most Americans every 70 days.
Not realistic, to say the least. Independent of the unknown dangers of a shot rate reaching that frequency, which you haven't yet addressed.
Everyone in this study had to be eligible for the booster which presumably means they were already vaccinated.

We've given well over half a billion shots in the US and I haven't seen an increasing rate of any particular problems. Absence of evidence isn't evidence of absence but given the number of multiply vaccinated people I'd expect to see a problem if there were one.
