You may be eligible if
1. An informed consent document signed and dated by the participant and the Investigator.
2. Male or female, age between 18 and 30 years inclusive (at the time of consent)
3. Seronegative to the challenge virus SARS-CoV-2, no history of SARS-CoV-2 infection and no previous participation in a SARS-CoV-2 vaccine trial.
4. Female participants with a documented menstrual period within 28 days before the inoculation (unless using a contraceptive method that suppressed menstruation as indicated in the study protocol) and willing and able to use contraception as described in the study protocol from 2 weeks before the scheduled date of viral challenge until 90 days after receipt of the final dose of rescue medication. Negative urine pregnancy tests will be required at screening and on day 0 prior to inoculation. On admission to the quarantine unit a Negative serum beta human chorionic gonadotropin (β-hCG) is required.
Contraceptive requirements:
Established use of hormonal methods of contraception described below (for 2 weeks prior to the first study visit). When hormonal methods of contraception are used, male partners are required to use a condom with a spermicide:
1. combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: i. oral ii. intravaginal iii. transdermal
2. . progestogen-only hormonal contraception associated with inhibition of ovulation: i. oral ii. injectable iii. implantable
3. Intrauterine device (IUD)
4. . Intrauterine hormone-releasing system (IUS)
5. . Bilateral tubal ligation
6. . Male sterilisation (with the appropriate post vasectomy documentation of the absence of sperm in the ejaculate) where the vasectomised male is the sole partner for that woman.
7. . True abstinence - sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.
5 Men who are willing to use one of the contraception methods described in the study protocol, from the time of the date of viral challenge, until 90 days after receipt of the final dose of study medication.
Contraceptive requirements:
1. Use a condom with a spermicide to prevent pregnancy in a female partner or to prevent exposure of any partner (male and female) to the study virus or Remdesivir.
2. Male sterilisation with the appropriate post vasectomy documentation of the absence of sperm in the ejaculate (please note that the use of condom with spermicide will still be required to prevent partner exposure). This applies only to males participating in the study.
3. In addition, for female partners of child bearing potential, that partner must use another form of contraception such as one of the highly effective methods mentioned above for female subjects.
4. True abstinence - sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.
In addition to the contraceptive requirements above, male subjects must agree not to donate sperm following discharge from quarantine until 90 days after the date of study virus or Remdesivir. (whichever occurs last).
