Safety Study of S.Flexneriza-S.Sonnei Bivalent Conjugate Vaccine in Healthy Volunteers Aged Above 3 Months

A Phase 1 interventional study of S.Flexneriza-S.Sonnei Bivalent Conjugate Vaccine and S.Flexneriza-S.Sonnei Bivalent Conjugate Vaccine in Dysentery and Dysentery, Bacillary, sponsored by Beijing Zhifei Lvzhu Biopharmaceutical Co., Ltd. Completed at 1 site in China. Open to participants aged 3 Months and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2018-10-17.

Primary conditionDysentery, BacillaryRegistry: DysenteryReclassifiedWhy we changed it
Registry
Dysentery — the first condition term the registry derived for this study.
ClinicalTrials.gg
Dysentery, Bacillary
Why
  1. The study's listed conditions name Dysentery, Bacillary, a narrower term within Dysentery.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

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.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
