       Amendment 1 to Form S-1 filed on November 5, 2021

       Prospectus Summary, page 1

   1.                                                   We note you disclosed
that you adjusted all share and per share numbers in your
                                                        filing, other than your
historical financial statements and related notes including your
                                                        summary financial data
on page 11, for a stock split of the outstanding shares of your
                                                        common stock (following
the conversion of your preferred stock) at a ratio of 4:1 to be
                                                        effected immediately
prior to the pricing of this offering. Prior to going effective, please
                                                        revise your historical
financial statements to reflect the reverse stock split based upon the
                                                        guidance in ASC
260-10-55-12 and SAB Topic 4(C) or alternatively, please tell us how
                                                        you complied with this
guidance.
   2.                                                   Please have your
independent auditors tell us their consideration of the need for them to
                                                        reference and dual-date
their audit opinion related to the aforementioned stock split.

3.       We note your response to prior comment 6, which we reissue in part.
You state that you
         have revised disclosure throughout the prospectus to ensure tables and
graphics included
         are legible. However, we observe that there are still numerous
instances where the
         revisions are not sufficient to render your disclosures easily
readable. By way of example
         and not limitation, we refer you to Table 2 on page 85 and the first
paragraph following
         Table 2 on page 86. The subscript used to identify the footnotes in
Table 2, as well as the
         revisions on page 86 intended to provide the citations for these
footnotes, is too small to
         be clear. Accordingly, please further review and revise as appropriate
throughout the
         prospectus.

BWV-201 Streptococcus pneumoniae (S. pneumoniae) Vaccine, page 92

4.       We note your response to prior comment 7, which we reissue with
respect to Figure 7
         (formerly Figure A). Please further revise your disclosure and/or
Figure 7 on page page
         95 to help investors better understand the preclinical head-to head
results you are
         including to compare your vaccine strain to Prevnar 7, Prevnar 13 and
Pneumovax. To
         this end, please clarify how each vaccine strain listed on the x-axis
corresponds to the
         vaccine names used in your narrative disclosure. For example, if true,
revise Figure 7 to
         indicate whether "PCV7" corresponds to Prevnar 7, whether BHN97DftsY
corresponds to
         BWV-201, and so on.

         Additionally, with respect to graphs A and B in Figure 8, revise to
clarify whether the x-
         axis references to "vaccine" are to BHN97DftsY, and if true, whether
this is the strain
         corresponding to BWV-201.

5.       We note your responses to comment 19 from the staff's initial comment
letter dated
         October 8, 2021, and to prior comment 10. Please note that we consider
the information
         requested in the prior comments to be material to investors and
therefore it is our position
         that providing a range rather than quantifying the dollar amounts as
requested is not
         appropriate. As such, we again reissue the comment in relevant part.
Revise your
         disclosures regarding each of your license and option agreements to
include a discussion
         of all material payment terms, including quantification of the
following:
             Up-front, deferred, or execution payments paid or received. In
this regard, we refer
              you by way of example and not limitation to phrases such as    a
one-time low ten-
              thousands initial license fee" or "a low hundred-thousands
deferred license fee" on
              page 120.
             Annual maintenance fees. In this regard, we refer you by way of
example and not
              limitation to phrases such as "an annual maintenance fee in the
low tens of
              thousands" on page 123.

             Aggregate amounts paid or received. In this regard, we refer you
by way of example
           and not limitation to statements such as the following: "The Company
is obligated to
           pay, and has paid, a low 5-digit number of British pounds to OUI for
any past patent
           expenses that were incurred prior to the execution of the OUI
Agreement."
6.    We also note that a portion of prior comment 10, which we reissue here,
was not
      addressed in either your disclosure or your response letter. With respect
to the OUI
      license agreement, please revise your disclosure on page 123 to state the
highest
         minimum sum    of royalties that must be paid to OUI in any year
before application of
      the    step down.    Please disclose the period of years over which the
step-down will apply
      before the minimum sum is reduced to zero.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
