Eligibility
Key inclusion criteria
1. Evidence of a personally signed and dated informed consent document (ICD) indicating
that the subject has been informed of all pertinent aspects of the study.

2. Healthy adults who are determined by medical history, physical examination, and
clinical judgment of the investigator to be eligible for inclusion in the study.

3. Willing and able to comply with scheduled visits, vaccination plan, laboratory tests,
and other study procedures.

4. Male and nonchildbearing-potential female adults aged 65 to 85 years at the time of
enrollment (signing of the ICD).
Minimum age
65 Years
Maximum age
85 Years
Gender
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Investigator site staff members directly involved in the conduct of the study and
their family members, site staff members otherwise supervised by the investigator, or
subjects who are Pfizer employees, including their family members, directly involved
in the conduct of the study.

2. Participation in other studies involving investigational product within 28 days prior
to study entry and/or during study participation.

3. Known infection with HIV, hepatitis C virus (HCV), or hepatitis B virus (HBV).

4. Previous vaccination with any licensed or investigational RSV vaccine, or planned
receipt throughout the study of nonstudy RSV vaccine.

5. Vaccination with any influenza vaccine within 6 months (182 days) before
investigational product administration.

6. History of severe adverse reaction associated with a vaccine and/or severe allergic
reaction (eg, anaphylaxis) to any component of the investigational product(s),
including natural rubber latex. In addition, a history of severe allergic reaction
(eg, anaphylaxis) to any substance, including documented allergy to egg proteins (egg
or egg products) or chicken proteins.

7. Subjects with known or suspected immunodeficiency, as determined by history and/or
laboratory/physical examination.

8. Subjects who receive treatment with immunosuppressive therapy, including cytotoxic
agents or systemic corticosteroids, eg, for cancer or an autoimmune disease, or
planned receipt throughout the study. If systemic corticosteroids have been
administered short term (<14 days) for treatment of an acute illness, subjects should
not be enrolled into the study until corticosteroid therapy has been discontinued for
at least 28 days before investigational product administration.Inhaled/nebulized,
intra-articular, intrabursal, or topical (epidural, skin or eyes) corticosteroids are
permitted.

9. Subject with a history of autoimmune disease or an active autoimmune disease requiring
therapeutic intervention including but not limited to: systemic or cutaneous lupus
erythematosus, autoimmune arthritis/rheumatoid arthritis, Guillain-Barré
syndrome,multiple sclerosis, Sjögren syndrome, idiopathic thrombocytopenic purpura,
autoimmune glomerulonephritis, autoimmune thyroiditis, giant cell arteritis (temporal
arteritis), psoriasis, and insulin-dependent diabetes mellitus (type 1).

10. Receipt of blood/plasma products or immunoglobulin, from 60 days before
investigational product administration or planned receipt throughout the study.

11. Bleeding diathesis or condition associated with prolonged bleeding that would, in the
opinion of the investigator, contraindicate intramuscular injection.

12. Female subjects of childbearing potential or who are pregnant or breastfeeding;
fertile male subjects who are unwilling to use a highly effective method of
contraception for at least 28 days after the last dose of investigational product.

13. Other acute or chronic medical or psychiatric condition including recent (within the
past year) or active suicidal ideation or behavior or laboratory abnormality that may
increase the risk associated with study participation or investigational product
administration or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the subject inappropriate for entry into this
study.
