Biopharma shareholders

2.       We note your response to our previous comment 8 and updated disclosure
on page 13 and
         reissue. Please disclose the Sponsor and its affiliates total
potential ownership interest in
         the combined company, assuming the exercise and conversion of all
securities. For
         example only, we note your disclosure on page 360 discussing working
capital
         loans between the Sponsor and Summit that may be convertible into
warrants at a price of
         US$1.00 per warrant and we note the Sponsor appears to hold "6,000,000
Summit Private
         Warrants" which do not appear to be reflected in your revised
disclosure on page 13.

3.       We note your response to our previous comment 11, including your
reference to a
         "concert party agreement" between All Brilliance Investments Limited,
Hopeful World
         Company Limited, Apex Pride Global Limited and Acton Town
International Limited (the
            Concert Parties   ). Please clarify whether this agreement will
continue after the Business
         Combination. If so, please file the agreement as an exhibit and
describe the material terms
         of the agreement or otherwise advise.
Anticipated Accounting Treatment, page 42

4.       We note your revisions in response to our previous comment 42. Your
discussion of the
         anticipated accounting treatment for the transaction on pages 42 and
174, however,
         continues to make references to IFRS. Please revise accordingly.

Timeline of the Business Combination, page 162

5.       We note your response to our previous comment 20, including your
revised disclosure on
         page 162 and reissue. For example only, based on the disclosures in
the revised Timeline
         of the Business Combination, it remains unclear where each party stood
with respect to
         the valuation and commercial arrangements of the Business Combination
from initiation
         of discussions in May 2022 until the letter of intent was signed July
1, 2022. Please revise
         your disclosure to explain the reasons for the terms, each party's
position on the issues,
         how and why they evolved over time from initiation of discussions
until September 29,
         2022, and how you reached agreement on the final terms.

6.       We note your response to our previous comment 22, including your
updated disclosure on
         page 164 and reissue. Please identify each advisor that the Summit
Board consulted with.
         In addition, we note Summit's press release dated September 29, 2022
states that Ogier
         served as a legal advisor to Summit in connection with the Business
Combination;
         however, Ogier does not appear to be mentioned in your draft
registration statement.
Summary of Valuation Analysis and Opinion of Financial Advisor to the Summit
Board
Overview, page 169

7.       We note your response to our previous comment 23 and reissue. We note
that your Board
         considered a fairness opinion prudent in light of the potential
conflicts of interest; that the
         fairness opinion was provided to the Board prior to its vote on the
Business Combination;
         and that the YS Biopharma financial projections were used by Summit
s financial advisor
         to conduct its analyses. Therefore, we continue to believe that
disclosure of the YS
         Biopharma financial projections are material to an assessment of the
value of the merger
         consideration and the financial analyses performed by ValueScope. In
addition, please
         disclose the material assumptions and underlying bases of the
financial projections
         provided by YS Biopharma and discuss the "certain adjustments" made by
         ValueScope, and any limitations of the projections. For example only,
please disclose if
         such projections included assumptions regarding potential future
product candidate
         approvals.
8.       You state that ValueScope's analysis consisted of multiple factors
including a review of
         data of comparable companies and industry transactions. Pursuant to
Item 1015(b)(6) of
         Regulation M-A, please amend your disclosure to include the comparable
companies and
         industry transactions reviewed, how they were selected, and the
respective valuations. In
         this regard, for example, we note the comparable company valuation
benchmarking
         analysis provided on slide 16 of the corporate presentation filed in
Exhibit 99.2 to
         Summit's Form 8-K filed September 29, 2022.

9.       We note your response to our previous comment 33 regarding the
head-to-head clinical
         studies. You state that four head-to-head studies were conducted by
certain CDC centers
         in China but we note only two studies appear to be discussed, one
conducted by Guangxi
         CDC and the other by Guizhou CDC. To the extent the other two
head-to-head studies
         were relied on, please amend to include the material details of such
studies, including a
         discussion of the trial design, who conducted the study, number of
participants, and other
         rabies vaccines studied or otherwise advise.

Warrants issued by
         Summit in connection with its IPO, please tell us whether you
anticipate any change in
         classification between liabilities and equity upon consummation of the
business
         combination. If so, please revise your pro forma financial statements
accordingly.

Note 3. Summary of Significant Accounting Policies
Revenue from Contracts with Customers, page F-53

12.      We note your response to our previous comment 46 and the revisions
made to your
         revenue recognition accounting policy disclosure. Your accounting
policy appears
         boilerplate and is not specific to your business. Accordingly, please
address the following:
             Specify the point in time that you determine control has
transferred to the customer
             and the performance obligation has been satisfied. For example,
clarify whether this
             occurs at the time of shipping, upon delivery to external service
providers, or
             customer acceptance.
             Clearly disclose that your revenue contracts with customers do not
involve variable
             considerations, such as discounts and rebates, as you stated in
your response.
             Provide us with a detailed description of your sales arrangements
with external
             service providers and clearly explain the purpose of the guarantee
deposits. In this
             regard, your disclosure on page F-64 that such deposits are
provided by service
             providers "in case they fail to sell the vaccines according to the
contract
             requirements" raises the question of whether the service providers
assume inventory
             risk for the vaccines before they are transferred to the end
customer. Explain your
             consideration of ASC 606-10-55-36 through 55-40 as it relates to
these arrangements.
Note 4. Accounts Receivable, Net, page F-59

13.      We note your response to our previous comment 47 and the aging
analysis provided.
         Please revise your filing as follows:
             Disclose both the contractual and customary payment terms for your
accounts
             receivable.
             Disclose your accounting policy for writing-off accounts
receivable deemed to be
             uncollectible.
             Clarify whether any of your accounts receivable have been
written-off (i.e., charged

           against the allowance) and if so, include the amount of such
write-offs in your
           rollforward of the allowance for doubtful accounts.
             Consider providing a rollforward of your accounts receivable
balance that shows the
           impact of current year sales and customer payments.
             Revise your MD&A to discuss the reasons for any changes in your
Days Sales
           Outstanding for each period presented.
