Inclusion criteria

  1. Approved .
  2. Men and women aged 18- 65 years.
  3. Written confirmation on previous immunization against diphtheria and tetanus not older than 16 years and not younger than 4 years.

Exclusion criteria

Exclusion Criteria:

  1. Subject with acute infectious diseases.
  2. Subject allergic to any of the substances of the IMP administered in clinical trial.
  3. Subject with Guillain-Barré syndrome or neuropathy, an anaphylactic or other allergic reactions after previous vaccination against tetanus or diphtheria.
  4. Subject with primary or secondary immunodeficiency (e.g. congenital immunodeficiency, infection, organ or bone marrow transplantation, leukemia, lymphoma, Hodgkin's disease, multiple myeloma, generalized , drugs or other causes induced immunodeficiency).
  5. Subject with progressive or unstable neurological disorder.
  6. Subject with severe thrombocytopenia or any coagulation disorder not allowing the intramuscular administration.
  7. Subject with blood product treatment, including immunoglobulins within the last 90 days prior to study entry.
  8. Subject vaccinated less than 14 days inactivated or prior to study entry.
  9. Pregnant woman and breastfeeding (anamnestically).
  10. Subject incapable of cooperation.
  11. Alcohol or drug abuse.
  12. Subject currently participating in another clinical trial or in drug evaluation, within 4 weeks prior to study entry.
  13. Subjects requiring vaccination against tetanus after severe injury.
  14. Any other condition that in the Investigator's opinion may affect the safety of the test participant or the integrity of data obtained during the study.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

What researchers measure

Primary outcomes

  1. Seroconversion

    The primary endpoint is the seroconversion in 28 days follow-up. The proportion of subjects complying the positive criteria of seroconversion will be calculated.

    Time frame: 28 days

Secondary outcomes

  1. The ratio of geometric mean concentrations (GMC) of post-vaccination tetanus antibodies and diphtheria antibodies between test and reverence.

    1. The ratio of geometric mean concentrations (GMC) of post-vaccination tetanus antibodies between test and reference vaccine in 28 days FU. 2. The ratio of geometric mean concentrations (GMC) of post-vaccination diphtheria antibodies between test and reference va1. The ratio of geometric mean concentrations (GMC) of post-vaccination tetanus antibodies between test and reference vaccine in 28 days FU.
