inclusion criteria: to be included in this study, each individual must satisfy all the following criteria: medically stable adult male or females ≥ 50 to ≤ 80 years of age at screening. participants may have 1 or more chronic medical diagnoses, but should be clinically stable as assessed by: absence of changes in medical therapy in the past 2 months due to treatment failure or toxicity; absence of medical events qualifying as saes within 3 months; and absence of known, current, and life-limiting diagnoses which render survival to completion of the protocol unlikely in the opinion of the investigator. the participant has a body mass index (bmi) of 17 to 40 kg/m2, inclusive, at screening. willing and able to give informed consent prior to study enrollment. able to attend study visits, comply with study requirements, and provide reliable and complete reports of aes. participants must have completed a primary vaccination series against sars-cov-2 with an authorized covid 19 vaccine (and fulfill national recommendations for his/her age and morbidity category) with receipt of second/last dose of authorized vaccine (with or without boosters[s]) ≥ 8 weeks prior to enrollment (first study vaccination). women of childbearing potential (defined as any female participant who is not surgically sterile [ie, hysterectomy, bilateral tubal ligation, or bilateral oophorectomy] or postmenopausal [defined as amenorrhea at least 12 consecutive months]) must agree to be heterosexually inactive from at least 28 days prior to enrollment and through the end of the study or agree to consistently use a medically acceptable method of contraception listed below from at least 28 days prior to enrollment and through the end of the study condoms (male or female) with spermicide (if acceptable in country) diaphragm with spermicide cervical cap with spermicide intrauterine device oral or patch contraceptives norplant®, depo-provera®, or other in-country regulatory approved contraceptive method that is designed to protect against pregnancy abstinence, as a form of contraception, is acceptable if in line with the participant's lifestyle participants must be healthy and medically stable, as determined by the investigator (based on review of health status, vital signs [to include body temperature], medical history, and targeted physical examination [to include body weight]). vital signs must be within medically acceptable ranges prior to vaccination. participants must agree to not participate in any other sars-cov-2 or influenza prevention or treatment studies for the duration of the study. note: for participants who become hospitalized with covid-19, participation in investigational treatment studies is permitted.

if an individual meets any of the following criteria, he or she is ineligible for this study: history of laboratory-confirmed (by polymerase chain reaction (pcr) or rapid antigen test) covid-19 or asymptomatic sars-cov-2 infection ≤ 8 weeks prior to enrollment. (note: symptomatic covid-19 or asymptomatic sars-cov-2 infection > 8 weeks prior to enrollment is not exclusionary) any ongoing, symptomatic acute illness requiring medical or surgical care or chronic illness that required changes in medication in the past 2 months indicating that chronic illness/disease is not stable (at the discretion of the investigator). this includes any current workup of undiagnosed illness that could lead to a new condition. serious chronic diseases inclusive of: uncontrolled hypertension (note: well controlled hypertension ≤ grade 2 in not exclusionary); congestive heart failure with a history of an acute exacerbation of any severity in the prior 2 years (note: mild well-controlled congestive heart failure is not exclusionary); chronic obstructive pulmonary disease (copd) with a history of an acute exacerbation of any severity in the prior 2 years (note: mild well-controlled copd is not exclusionary); in the past 3 months, evidence of unstable coronary artery disease as manifested by cardiac interventions (eg, cardiac stent placement, coronary artery bypass grafting [cabg]) surgery, new cardiac medications for control of symptoms, or unstable angina (note: stable coronary heart disease is not exclusionary); asthma with a history of exacerbation in the prior 2 years or worsening of asthma symptoms or requiring changes in asthma control medications in the past 2 months (note: well-controlled asthma is not exclusionary). type 1 or type 2 diabetes (adult onset) requiring insulin (note: non-insulin dependent type 2 diabetes is not exclusionary); chronic kidney disease/renal insufficiency; chronic gastrointestinal and hepatic diseases; or chronic neurological diseases (such as multiple sclerosis, dementia, parkinson's disease, degenerative neurological conditions, neuropathy, or epilepsy), history of stroke within 12 months with residual symptoms, or previous neurological disorder within 12 months with residual symptoms (note: history of migraine or chronic headaches or nerve root compression that have been stable on treatment for the last 4 weeks are not exclusionary). participation in research involving an investigational product (drug/biologic/device) within 90 days before planned date of vaccination. use of covid-19 prophylactic or treatment monoclonal antibodies or antibody cocktails within 90 days prior to planned date of vaccination. history of a serious reaction to prior influenza vaccination or known allergy to constituents of influenza vaccines - including egg proteins - or polysorbate 80; or any known allergies to products contained in the investigational product. any history of anaphylaxis to any prior vaccine. history of guillain-barré syndrome within 6 weeks following a previous influenza vaccine. receipt of any vaccine in the 4 weeks preceding the study vaccination and any influenza vaccine within 8 weeks preceding the study vaccination. note: routine vaccinations will not be allowed until after study day 21 and covid and influenza vaccination will not be allowed until after day 84. any known or suspected autoimmune or immunosuppressive illness, congenital or acquired, based on medical history and/or physical examination (note: mild psoriasis is not exclusionary). chronic administration (defined as more than 14 continuous days) of immunosuppressants or other immune- modifying drugs within 6 months prior to the administration of the study vaccines. an immunosuppressant dose of glucocorticoid is defined as a systemic dose ≥ 10 mg of prednisone per day or equivalent. the use of topical, inhaled, and nasal glucocorticoids is permitted. administration of immunoglobulins and/or any blood products within the 3 months preceding the administration of the study vaccine or during the study. active cancer (malignancy) therapy within 3 years prior to study vaccination (with the exception of adequately treated non-melanomatous skin carcinoma or lentigo maligna and uterine cervical carcinoma in situ without evidence of disease, at the discretion of the investigator). participants who are breastfeeding, pregnant, or who plan to become pregnant prior to the end of study (eos). known disturbance of coagulation. suspected or known history of alcohol abuse or drug addiction within 2 years prior to study vaccination, which in the opinion of the investigator, might interfere with protocol compliance. acute disease at the time of enrollment (defined as the presence of a moderate or severe illness with or without fever, or an oral temperature > 38.0°c, on the planned day of vaccine administration). history of myocarditis or pericarditis. any condition that in the opinion of the investigator would pose a health risk to the participant if enrolled or could interfere with evaluation of the vaccine or interpretation of study results (including neurologic or psychiatric conditions deemed likely to impair the quality of safety reporting). study team member or immediate family member of any study team member (inclusive of sponsor, contract research organization, and study site personnel involved in the conduct or planning of the study.
