of July 2015 , MERS - CoV cases have been reported in over
21 countries. The outbreaks of MERS - CoV have raised
serious concerns world -wide, reinforcing the importance of
developing effective and safe vaccine candidates against
unwanted cellular responses , RNA ( e.g. , mRNA ) vaccines
are presented to the cellular system in a more native fashion .
In some aspects the invention is a respiratory virus
vaccine, comprising at least one RNA polynucleotide having
an open reading frame encoding at least one respiratory
virus antigenic polypeptide , formulated in a cationic lipid
nanoparticle.
Surprisingly, in some aspects it has also been shown that
efficacy of mRNA vaccines can be significantly enhanced
when combined with a flagellin adjuvant, in particular, when
one or more antigen - encoding mRNAs is combined with an
mRNA encoding flagellin .
RNA ( e.g. , mRNA ) vaccines combined with the flagellin
adjuvant (e.g. , mRNA - encoded flagellin adjuvant) have
superior properties in that they may produce much larger
antibody titers and produce responses earlier than commer
cially available vaccine formulations. While not wishing to
be bound by theory, it is believed that the RNA ( e.g. ,
mRNA ) vaccines , for example, as mRNA polynucleotides,
are better designed to produce the appropriate protein con
formation upon translation , for both the antigen and the
adjuvant, as the RNA (e.g. , mRNA ) vaccines co - opt natural
cellular machinery. Unlike traditional vaccines , which are
manufactured ex vivo and may trigger unwanted cellular
responses, RNA (e.g. , mRNA ) vaccines are presented to the
cellular system in a more native fashion .
Some embodiments of the present disclosure provide
RNA ( e.g. , mRNA ) vaccines that include at least one RNA
(e.g. , mRNA ) polynucleotide having an open reading frame
encoding at least one antigenic polypeptide or an immuno
genic fragment thereof ( e.g. , an immunogenic fragment
capable of inducing an immune response to the antigenic
polypeptide) and at least one RNA (e.g. , mRNA polynucle
otide ) having an open reading frame encoding a flagellin
adjuvant.
In some embodiments, at least one flagellin polypeptide
( e.g., encoded flagellin polypeptide ) is a flagellin protein. In
some embodiments, at least one flagellin polypeptide ( e.g. ,
encoded flagellin polypeptide) is an immunogenic flagellin
fragment. In some embodiments, at least one flagellin poly
peptide and at least one antigenic polypeptide are encoded
by a single RNA ( e.g. , mRNA ) polynucleotide. In other
embodiments, at least one flagellin polypeptide and at least
one antigenic polypeptide are each encoded by a different
RNA polynucleotide.
In some embodiments at least one flagellin polypeptide

SUMMARY
Provided herein are ribonucleic acid ( RNA ) vaccines that
build on the knowledge that RNA ( e.g. , messenger RNA
(mRNA )) can safely direct the body's cellular machinery to
produce nearly any protein of interest, from native proteins
to antibodies and other entirely novel protein constructs that
can have therapeutic activity inside and outside of cells . The
RNA (e.g. , mRNA ) vaccines of the present disclosure may
be used to induce a balanced immune response against
hMPV, PIV , RSV, MeV, and / or BetaCoV (e.g. , MERS - COV,
SARS -COV, HCOV -OC43, HCOV -229E , HCOV -NL63,
HCOV - NL , HCOV - NH and / or HCOV -HKU1 ), or any combination of two or more of the foregoing viruses, comprising
both cellular and humoral immunity, without risking the
possibility of insertional mutagenesis, for example. hMPV,
PIV, RSV, MeV, BetaCoV (e.g. , MERS - CoV, SARS - CoV,
HCOV - OC43, HCOV -229E , HCOV -NL63, HCOV -NL ,

referred to herein as “ respiratory viruses.” Thus, the term
“ respiratory virus RNA vaccines” encompasses hMPV RNA
vaccines , PIV RNA vaccines, RSV RNA vaccines , MeV

DETAILED DESCRIPTION
The present disclosure provides, in some embodiments,
vaccines that comprise RNA ( e.g. , mRNA ) polynucleotides
encoding a human Metapneumovirus (hMPV ) antigenic
polypeptide , a parainfluenza virus type 3 (PIV3 ) antigenic
polypeptide , a respiratory syncytial virus ( RSV ) antigenic
polypeptide , a measles virus (MeV) antigenic polypeptide,
or a Betacoronavirus antigenic polypeptide (e.g. , Middle
East respiratory syndrome coronavirus (MERS - CoV ) ,
SARS - CoV, human coronavirus ( HCOV) -OC43 , HCOV229E , HCOV -NL63, HCOV -NL , HCOV - NH (New Haven)
and HCOV -HKU1) ( see , e.g. , Esper F. et al . Emerging
Infectious Diseases, 12 ( 5 ) , 2006 ; and Pyrc K. et al . Journal
of Virology, 81 (7 ) : 3051-57 , 2007 , the contents of each of
which is here incorporated by reference in their entirety ).
The present disclosure also provides, in some embodiments,
combination vaccines that comprise at least one RNA ( e.g. ,
mRNA ) polynucleotide encoding at least two antigenic
polypeptides selected from hMPV antigenic polypeptides,
PIV3 antigenic polypeptides , RSV antigenic polypeptides,
MeV antigenic polypeptides and BetaCoV antigenic polypeptides. Also provided herein are methods of administering
the RNA ( e.g. , mRNA ) vaccines , methods of producing the
RNA ( e.g. , mRNA ) vaccines, compositions ( e.g. , pharmaceutical compositions ) comprising the RNA ( e.g. , mRNA )
vaccines , and nucleic acids ( e.g. , DNA ) encoding the RNA

repeat domains at the N- and C - terminal regions of the
protein (HR1 and HR2 ) , which form coiled- coil alpha
helices . These coiled coils become apposed in an antiparallel
fashion when the protein undergoes a conformational
change into the fusogenic state . There is a hydrophobic
fusion peptide N proximal to the N -terminal heptad repeat ,
which is thought to insert into the target cell membrane,
while the association of the heptad repeats brings the trans
membrane domain into close proximity, inducing membrane
fusion ( see , e.g. , Baker, K A et al . Mol. Cell 1999 ; 3: 309
319 ) . This mechanism has been proposed for a number of
different viruses , including RSV, influenza virus, and human
immunodeficiency virus . Fusion proteins are major anti
genic determinants for all known paramyxoviruses and for
other viruses that possess similar fusion proteins such as
human immunodeficiency virus, influenza virus, and Ebola
virus .

disclosure comprises a RNA (e.g. , mRNA ) polynucleotide
encoding hMPV fusion protein (F ) . In some embodiments,

infection , the F glycoprotein mediates penetration of the
host cell by fusion of the viral envelope to the plasma
membrane . In later stages of the infection, the F protein
facilitates the fusion of the infected cells with neighboring
uninfected cells , which leads to the formation of a syncytium 5
and spread of the infection .
PIV3 matrix protein ( M) is found within the viral envelope and assists with viral assembly. It interacts with the
nucleocapsid and envelope glycoproteins , where it facilitates the budding of progeny viruses through its interactions 10
with specific sites on the cytoplasmic tail of the viral
glycoproteins and nucleocapsid. It also plays a role in
transporting viral components to the budding site .
PIV3 phosphoprotein ( P ) and PIV3 large polymerase
protein (L ) are found in the nucleocapsid where they form 15
part of the RNA polymerase complex. The L protein , a viral
RNA -dependent RNA polymerase, facilitates genomic transcription , while the host cell’s ribosomes translate the viral
mRNA into viral proteins.
PIV3 V is a non -structural protein that blocks IFN sig- 20
naling in the infected cell , therefore acting as a virulence
factor.
PIV3 nucleoprotein ( N ) encapsidates the genome in a
ratio of 1 N per 6 ribonucleotides, protecting it from
nucleases. The nucleocapsid (NC ) has a helical structure . 25
The encapsidated genomic RNA is termed the NC and
serves as template for transcription and replication . During
replication , encapsidation by PIV3 N is coupled to RNA
synthesis and all replicative products are resistant to nucleases . PIV3 N homo -multimerizes to form the nucleocapsid 30
and binds to viral genomic RNA . PIV3 N binds the P protein
and thereby positions the polymerase on the template.

at least 98 % or at least 99 % identity with PIV3 hemagglu
tinin -neuraminidase ( HN) and having hemagglutinin
neuraminidase activity.
A protein is considered to have hemagglutinin -neuramini
dase activity if, for example, it is capable of both receptor
binding and receptor cleaving. Such proteins are major
surface glycoproteins that have functional sites for cell
attachment and for neuraminidase activity . They are able to
cause red blood cells to agglutinate and to cleave the
glycosidic linkages of neuraminic acids , so they have the
potential to both bind a potential host cell and then release
the cell if necessary, for example , to prevent self -aggrega
tion of the virus.
In some embodiments, PIV3 vaccines comprise RNA
(e.g. , mRNA ) polynucleotides encoding PIV3 antigenic

MERS - Co V. MERS - CoV is a positive - sense , single
stranded RNA virus of the genus Betacoronavirus. The
genomes are phylogenetically classified into two clades ,
clade A and clade B. It has a strong tropism for non - ciliated
bronchial epithelial cells , evades the innate immune
response and antagonizes interferon ( IFN) production in
infected cells . Dipeptyl peptidase 4 (DDP4 , also known as
CD26 ) has been identified as a functional cellular receptor
for MERS -CoV. Its enzymatic activity is not required for
infection , although its amino acid sequence is highly con
served across species and is expressed in the human bron
chial epithelium and kidneys. Most infected individuals
develop severe acute respiratory illnesses , including fever,
cough, and shortness of breath , and the virus can be fatal.
The disease may be transmitted among humans, generally
among those in close contact.
The genome of MERS - CoV encodes at least four unique
accessory proteins, such as 3 , 4a , 4b and two replicase
proteins ( open reading frame la and 1b ) , and four major
structural proteins, including spike ( S ) , envelope ( E ) ,
nucleocapsid ( N ) , and membrane ( M ) proteins (Almazan F
et al . MBio 2013 ; 4 ( 5 ) : e00650-13 ) . The accessory proteins
play nonessential roles in MERS - CoV replication, but they
are likely structural proteins or interferon antagonists ,
modulating in vivo replication efficiency and / or pathogen
esis , as in the case of SARS - CoV (Almazan F et al . MBio
2013 ; 4 ( 5 ) : e00650-13 ; Totura A L et al . Curr Opin Virol
2012 ; 2 ( 3 ) : 264-75 ; Scobey T et al . Proc Natl Acad Sci USA
2013 ; 110 ( 40 ) : 16157-62 ) . The other proteins of MERS- CoV
maintain different functions in virus replication. The E
protein , for example, involves in virulence, and deleting the
E -coding gene results in replication -competent and propa
gation -defective viruses or attenuated viruses (Almazan F et
al . MBio 2013 ; 4 ( 5 ) : e00650-13 ) . The S protein is particu
larly essential in mediating virus binding to cells expressing
receptor dipeptidyl peptidase - 4 (DPP4 ) through receptor
binding domain (RBD ) in the S1 subunit, whereas the S2
subunit subsequently mediates virus entry via fusion of the
virus and target cell membranes (Li F. J Virol 2015 ; 89 ( 4 ) :

Such extremity is not limited only to the first or final site of
the polypeptide or polynucleotide but may include addi-

Polypeptide -based molecules may be characterized as having both an N - terminus ( terminated by an amino acid with
a free amino group (NH2 )) and a C - terminus ( terminated by
an amino acid with a free carboxyl group (COOH ) ) . Proteins
are in some cases made up of multiple polypeptide chains
brought together by disulfide bonds or by non - covalent
forces (multimers, oligomers ). These proteins have multiple
N- and C -termini.Alternatively, the termini of the polypeptides may be modified such that they begin or end , as the
case may be , with a non -polypeptide based moiety such as
an organic conjugate.
As recognized by those skilled in the art, protein fragments , functional protein domains, and homologous proteins
are also considered to be within the scope of polypeptides of

N -terminal 15-60 amino acids of proteins , are typically
needed for the translocation across the membrane on the
secretory pathway and, thus, universally control the entry of
most proteins both in eukaryotes and prokaryotes to the
secretory pathway. Signal peptides generally include three

Flagellin Adjuvants
Flagellin is an approximately 500 amino acid monomeric 5
protein that polymerizes to form the flagella associated with
bacterial motion . Flagellin is expressed by a variety of
flagellated bacteria ( Salmonella typhimurium for example )
as well as non - flagellated bacteria ( such as Escherichia coli ).
Sensing of flagellin by cells of the innate immune system 10
(dendritic cells , macrophages, etc. ) is mediated by the Tolllike receptor 5 ( TLR5 ) as well as by Nod - like receptors
(NLRs ) Ipaf and Naip5 . TLRs and NLRs have been identified as playing a role in the activation of innate immune
response and adaptive immune response . As such, flagellin 15
provides an adjuvant effect in a vaccine.
The nucleotide and amino acid sequences encoding
known flagellin polypeptides are publicly available in the
NCBI GenBank database . The flagellin sequences from S.
Typhimurium , H. Pylori, V. Cholera , S. marcesens, S. 20
flexneri, T. Pallidum , L. pneumophila, B. burgdorferei, C.
difficile, R. meliloti , A. tumefaciens, R. lupini, B. clarridgeiae, P. Mirabilis, B. subtilus, L. monocytogenes , P.
aeruginosa , and E. coli , among others are known .
A flagellin polypeptide, as used herein , refers to a full 25
length flagellin protein , immunogenic fragments thereof,
and peptides having at least 50% sequence identify to a
flagellin protein or immunogenic fragments thereof. Exemplary flagellin proteins include flagellin from Salmonella
typhi (UniPro Entry number: Q56086 ) , Salmonella typhimurium
( AOA0C9DG09 ),
Salmonella
enteritidis
( AOA0C9BAB7 ), and Salmonella choleraesuis (Q6V2X8 ) ,
and SEQ ID NO : 54-56 ( Table 17 ) . In some embodiments,

90 % , 95 % , 97 % , 98 % , or 99 % sequence identify to a
flagellin protein or immunogenic fragments thereof.
In some embodiments, the flagellin polypeptide is an
immunogenic fragment. An immunogenic fragment is a
portion of a flagellin protein that provokes an immune
response . In some embodiments, the immune response is a
TLR5 immune response . An example of an immunogenic
fragment is a flagellin protein in which all or a portion of a
hinge region has been deleted or replaced with other amino
acids . For example, an antigenic polypeptide may be
inserted in the hinge region. Hinge regions are the hypervariable regions of a flagellin. Hinge regions of a flagellin
are also referred to as “ D3 domain or region, " propeller
domain or region ," " hypervariable domain or region " and
“ variable domain or region .” “ At least a portion of a hinge
region ,” as used herein , refers to any part of the hinge region
of the flagellin , or the entirety of the hinge region . In other

In some embodiments, the RNA ( e.g. , mRNA ) vaccine
includes an RNA that encodes a fusion protein of flagellin
and one or more antigenic polypeptides. A " fusion protein ”
as used herein , refers to a linking of two components of the
construct. In some embodiments, a carboxy - terminus of the
antigenic polypeptide is fused or linked to an amino termi
nus of the flagellin polypeptide. In other embodiments, an
amino - terminus of the antigenic polypeptide is fused or
linked to a carboxy -terminus of the flagellin polypeptide .
The fusion protein may include , for example, one , two ,
three, four, five, six or more flagellin polypeptides linked to
one , two, three , four, five , six or more antigenic polypep
tides . When two or more flagellin polypeptides and / or two or
more antigenic polypeptides are linked such a construct may
be referred to as a "multimer.”
Each of the components of a fusion protein may be
directly linked to one another or they may be connected
through a linker. For instance, the linker may be an amino
acid linker. The amino acid linker encoded for by the RNA
(e.g. , mRNA ) vaccine to link the components of the fusion
protein may include , for instance, at least one member
selected from the group consisting of a lysine residue , a
glutamic acid residue, a serine residue and an arginine
residue . In some embodiments the linker is 1-30 , 1-25 , 1-25 ,
5-10 , 5 , 15 , or 5-20 amino acids in length .
In other embodiments the RNA (e.g. , mRNA ) vaccine
includes at least two separate RNA polynucleotides, one
encoding one or more antigenic polypeptides and the other
encoding the flagellin polypeptide . The at least two RNA
polynucleotides may be co -formulated in a carrier such as a
lipid nanoparticle.

peutic vaccines are particularly amenable to combination
vaccination approaches due to a number of factors includ

rapidly tailor vaccines to accommodate perceived geo
graphical threat, and the like . Moreover, because the vac
cines utilize the human body to produce the antigenic
protein , the vaccines are amenable to the production of

pharmaceutical agents, such as vaccine compositions , may
be found, for example , in Remington : The Science and
Practice of Pharmacy 21st ed . , Lippincott Williams &
Wilkins, 2005 ( incorporated herein by reference in its
entirety ).
In some embodiments, respiratory virus RNA (e.g.
mRNA ) vaccines are administered to humans, human
patients or subjects. For the purposes of the present disclosure , the phrase “ active ingredient “ generally refers to the
RNA (e.g. , mRNA ) vaccines or the polynucleotides contained therein , for example, RNA polynucleotides ( e.g. ,
mRNA polynucleotides) encoding antigenic polypeptides.

embodiments the length of the 3 '-poly ( A ) tail may be an
essential element with respect to the stability of the indi

In some embodiments the RNA ( e.g. , mRNA ) vaccine
may include one or more stabilizing elements. Stabilizing
elements may include for instance a histone stem - loop. A
stem - loop binding protein ( SLBP) , a 32 kDa protein has
been identified . It is associated with the histone stem - loop at
the 3 ' - end of the histone messages in both the nucleus and
the cytoplasm . Its expression level is regulated by the cell
cycle ; it peaks during the S -phase , when histone mRNA
levels are also elevated . The protein has been shown to be
essential for efficient 3 ' - end processing of histone pre
mRNA by the U7 snRNP. SLBP continues to be associated
with the stem - loop after processing , and then stimulates the
translation of mature histone mRNAs into histone proteins
in the cytoplasm . The RNA binding domain of SLBP is

The poly ( A ) sequence or polyadenylation signal generally
should enhance the expression level of the encoded protein .
The encoded protein, in some embodiments, is not a histone
protein , a reporter protein ( e.g. Luciferase, GFP, EGFP,
B - Galactosidase , EGFP ) , or a marker or selection protein
( e.g. alpha -Globin, Galactokinase and Xanthine :guanine

In some embodiments, the combination of a poly (A)
sequence or polyadenylation signal and at least one histone
stem - loop , even though both represent alternative mechanisms in nature , acts synergistically to increase the protein
expression beyond the level observed with either of the
individual elements . It has been found that the synergistic

stem - loop does not depend on the order of the elements or
the length of the poly( A ) sequence .
In some embodiments, the RNA ( e.g. , mRNA ) vaccine
does not comprise a histone downstream element ( HDE) .
“ Histone downstream element” ( HDE) includes a purinerich polynucleotide stretch of approximately 15 to 20
nucleotides 3 ' of naturally occurring stem - loops , representing the binding site for the U7 snRNA , which is involved in
processing of histone pre -mRNA into mature histone
mRNA . Ideally , the inventive nucleic acid does not include
an intron.
In some embodiments, the RNA ( e.g. , mRNA ) vaccine
may or may not contain a enhancer and / or promoter
sequence , which may be modified or unmodified or which
may be activated or inactivated . In some embodiments, the
histone stem - loop is generally derived from histone genes ,
and includes an intramolecular base pairing of two neighbored partially or entirely reverse complementary sequences
separated by a spacer, including ( e.g. , consisting of) a short
sequence, which forms the loop of the structure. The
unpaired loop region is typically unable to base pair with
either of the stem loop elements . It occurs more often in
RNA , as is a key component of many RNA secondary
structures, but may be present in single -stranded DNA as
well . Stability of the stem - loop structure generally depends
on the length , number of mismatches or bulges , and base
composition of the paired region . In some embodiments,
wobble base pairing ( non - Watson -Crick base pairing) may
result . In some embodiments, the at least one histone stemloop sequence comprises a length of 15 to 45 nucleotides.
In other embodiments the RNA (e.g. , mRNA ) vaccine
may have one or more AU - rich sequences removed . These
sequences , sometimes referred to as AURES are destabilizing sequences found in the 3'UTR . The AURES may be
removed from the RNA (e.g. , mRNA ) vaccines . Alterna-

the PEGylation , ratio of all components and biophysical
parameters such as size . In one example by Semple et al .
(Nature Biotech . 2010 28 : 172-176 ) , the lipid nanoparticle
5 formulation is composed of 57.1 % cationic lipid, 7.1 %
dipalmitoylphosphatidylcholine, 34.3 % cholesterol, and
1.4 % PEG - C - DMA. As another example, changing the com
position of the cationic lipid can more effectively deliver
siRNA to various antigen presenting cells (Basha et al . Mol
10 Ther . 2011 19 : 2186-2200 ) .
In some embodiments, lipid nanoparticle formulations
may comprise 35 to 45 % cationic lipid , 40 % to 50 % cationic
lipid , 50 % to 60 % cationic lipid and / or 55 % to 65 % cationic
lipid . In some embodiments , the ratio of lipid to RNA ( e.g. ,
15 mRNA ) in lipid nanoparticles may be 5 : 1 to 20 : 1 , 10 : 1 to
25 : 1 , 15 : 1 to 30 : 1 and /or at least 30 : 1 .

In some embodiments, the ratio of PEG in the lipid
nanoparticle formulations may be increased or decreased
and / or the carbon chain length of the PEG lipid may be
modified from C14 to C18 to alter the pharmacokinetics
and / or biodistribution of the lipid nanoparticle formulations .
As a non- limiting example, lipid nanoparticle formulations
may contain 0.5 % to 3.0 % , 1.0 % to 3.5 % , 1.5 % to 4.0% ,
2.0 % to 4.5 % , 2.5 % to 5.0 % and / or 3.0 % to 6.0% of the lipid

Lipid nanoparticle formulations may be improved by
replacing the cationic lipid with a biodegradable cationic
lipid which is known as a rapidly eliminated lipid nanoparticle ( reLNP ). Ionizable cationic lipids , such as , but not
limited to , DLinDMA, DLin -KC2 - DMA, and DLin -MC3DMA, have been shown to accumulate in plasma and tissues
over time and may be a potential source of toxicity. The
rapid metabolism of the rapidly eliminated lipids can
improve the tolerability and therapeutic index of the lipid
nanoparticles by an order of magnitude from a 1 mg/kg dose
to a 10 mg/kg dose in rat. Inclusion of an enzymatically
degraded ester linkage can improve the degradation and
metabolism profile of the cationic component, while still
maintaining the activity of the reLNP formulation . The ester
linkage can be internally located within the lipid chain or it
may be terminally located at the terminal end of the lipid
chain . The internal ester linkage may replace any carbon in
the lipid chain.
