No. The Scitechdaily link does not mention boosters. Neither does the Regenstrief page that links to. Neither does the CDC page that links to. Neither does the study PDF that that links to.
Additionally, the study cited indirectly in OP took place January 2021-September 2021. Boosters were not approved until the end of September 2021, and only for the smallest, most at-risk populations.
