Ann: Issuance of Milestone Shares Under Vaxinia Acquisition, page-32

All share holders will have the opportunity to vote.

Unlike the single vote right that individuals commonly possess in democratic governments, the number of votes a shareholder has corresponds to the number of shares they own.
Typically common shares carry one vote per share.
Thus, somebody owning more than 50% of a company's shares can effect a majority of the vote and is said to have a controlling interest in the firm.

From my experience voting rarely gets unapproved.
Only when major share holders are opposing each other, which is not the case here.
I consider the voting approval to be done as a formal obligation requirement.
