Brief Summary: https://clinicaltrials.gov/ct2/show/NCT04751682 1/9 7/5/2021 Safety and Immunogenicity of an Intranasal SARS-CoV-2 Vaccine (BBV154) for COVID-19 - Full Text View - ClinicalTrials.gov The study is designed to evaluate the safety, reactogenicity, and immunogenicity of three groups of healthy volunteers who receive either intranasal single dose (vaccine on Day 0 and placebo on Day 28) or two- dose (vaccine on Day 0 and 28) of BBV154 vaccine or Placebo (on Day 0 and day 28). A total of 175 subjects will be enrolled in 2:2:1 ratio and will be conducted in a double-blinded manner.
To assess the safety of the vaccine, each participant will record symptoms in a diary card for 7 days after each dose. Safety and laboratory tests and physical exams will also be performed.
Blood samples and saliva samples be collected to assess the immune response from the vaccine.
An interim report based on the safety and immunogenicity of the vaccine (BBV154) will be notified to the Central Drugs Standard Control Organization (CDSCO), India, for further progressing the clinical development of the vaccine. This unblinded interim report will contain a detailed analysis of the data based on the primary and secondary objectives of all visits through Day 42 (Immunogenicity & Safety).
