Summit Healthcare (NASDAQ:SMIH) announced that its shareholders have approved its combination with drug-maker YS Biopharma at a special meeting held earlier today.

The SPAC did not disclose redemption figures, but noted that the transaction is expected to deliver approximately $36 million in gross proceeds, which are expected to be used for the clinical development and future commercialization of the company’s vaccines.
