This is an interventional prevention trial for Covid19 focused on measuring Vaccine, Covid19 Vaccine Read More

Inclusion Criteria:

1. Subject read, understood, and signed the informed consent form (ICF).
2. Healthy adult males and females 18-49 years of age (Part A) or 50-85 years of age (Part B), inclusive, at screening.
3. RT-PCR negative at time of screening.
4. Body mass index (BMI) of ≥ 18 and ≤ 30 kg/m2 at screening. BMI = weight (kg)/(height [m])2.
5. Must be in general good health before study participation with no clinically relevant abnormalities that could interfere with study assessments.

6. Women of childbearing potential (WOCBP) and men whose sexual partners are WOCBP must be able and willing to use at least 1 highly effective method of contraception (ie, include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy, hormonal oral [in combination with male condoms with spermicide], transdermal, implant, or injection, barrier [ie, condom, diaphragm with spermicide]; intrauterine device; vasectomized partner [6 months minimum], clinically sterile partner; or abstinence) during the study. A female subject is considered to be a WOCBP after menarche and until she is in a postmenopausal state for 12 consecutive months (without an alternative medical cause) or otherwise permanently sterile. Note: Subjects not of childbearing potential are not required to use any other forms of contraception during the study. Non-childbearing potential is defined as subject confirmed:

   • Surgical sterilization (eg, bilateral oophorectomy, bilateral salpingectomy, bilateral occlusion by cautery [Essure System is not acceptable], hysterectomy, or tubal ligation).
   • Postmenopausal (defined as permanent cessation of menstruation for at least 12 consecutive months prior to screening) with FSH ≥ 30 mIU/mL at screening.
7. WOCBP must have a negative urine pregnancy test before each vaccination.
8. Must be able to attend all visits, including unscheduled visits if respiratory symptoms develop during the study, for the duration of the study and comply with all study procedures, including daily completion of the Diary Card for 7 days after each injection.

Exclusion Criteria

1. History of an acute or chronic medical condition including dementia that, in the opinion of the Investigator, would render vaccination unsafe or would interfere with the evaluation of responses. Chronic conditions that are NOT included on the Center for Disease Control's list of subjects at higher risk for severe illness from SARS-CoV-2 are acceptable if the condition has been stable for the 3 months prior to vaccine administration (Day 1), with no medication changes, and no hospitalization in the past 6 months.
2. History of any medical conditions that place subjects at higher risk for severe illness due to SARS-CoV-2 including but not limited to cancer, chronic kidney disease at any stage, chronic lung disease, dementia or other neurological conditions, diabetes (Type 1 or Type 2), Down syndrome, heart conditions, human immunodeficiency virus (HIV) infection, immunocompromised state (weakened immune system), liver disease, overweight/obesity, pregnancy, sickle cell disease or thalassemia, smoker (current or former), transplants (solid organ or blood stem cell), stroke or cerebrovascular disease, and substance use disorders.
3. History of ongoing clinical condition or medication or treatments that may adversely affect the immune system.
4. Individuals who are PCR positive for SARS-CoV-2 at screening or prior to second dose of TAP-COVID-19 vaccine.
5. Individuals who are at increased risk of exposure to SARS-CoV-2 (eg, healthcare workers, emergency responders).
6. Close contact of anyone known to have SARS-CoV-2 infection within 30 days prior to vaccine administration.
7. Living in a group care facility (eg, assisted living or nursing home).
8. Individuals with any elevated (Grade 1 or higher) laboratory test assessed as clinically significant for age by the Investigator at screening.
9. Individuals with any elevated (Grade 1 or higher) liver function enzyme at screening,
10. Active neoplastic disease (excluding nonmelanoma skin cancer that was successfully treated) or a history of any hematological malignancy. "Active" is defined as having received treatment within the past 5 years.
11. Long-term (greater than 2 weeks) use of oral or parenteral steroids, high-dose inhaled steroids (>800 μg/day of beclomethasone dipropionate or equivalent), or immunomodulatory drugs within 6 months before screening (nasal and topical steroids are allowed).
12. History of autoimmune, inflammatory disease, or potential immune-mediated medical conditions (Appendix B).
13. Women currently pregnant, lactating, or planning a pregnancy between enrollment and 181 days after randomization.
14. History of Guillain-Barré Syndrome.
15. History of anaphylactic-type reaction to injected vaccines.
16. Known or suspected hypersensitivity to 1 or more of the components of the vaccine, including thimerosal, tobacco, and CpG adjuvant.
17. History of alcohol abuse, illicit drug use, physical dependence to any opioid, or any history of drug abuse or addiction within 12 months of screening.
18. Acute illness or fever within 3 days before study enrollment (enrollment may be delayed for full recovery if acceptable to the Investigator).
19. Individuals currently participating or planning to participate in a study that involves an experimental agent (vaccine, drug, biologic, device, or medication); or who have received an experimental agent within 1 month (3 months for immunoglobulins) before enrollment in this study; or who expect to receive another experimental agent during participation in this study.
20. Receipt of immunoglobulin or another blood product within the 3 months before enrollment in this study or those who expect to receive immunoglobulin or another blood product during this study.
21. Individuals who intend to donate blood within 6 months after the first vaccination.
22. Individuals using prescription medications for prophylaxis of SARS-CoV-2.
23. Individuals who plan to receive another vaccine within the first 3 months of the study except influenza vaccine which should not be given within 2 weeks of study vaccine.
24. Receipt of any other approved SARS CoV 2 vaccine prior to the first study vaccine or within 90 days after administration of the first study vaccine.
25. Receipt of any other experimental coronavirus vaccine at any time prior to or during the study.
26. Receipt of any investigational vaccine or drug within 1 month of enrollment and through the end of the study (1 year after first vaccination).
