Abstract

fetched live from OpenAlex

Since the COVID-19 outbreak began, there has been an urgent need for a safe and effective vaccine to end this global pandemic. One such vaccine is the Ad5-nCoV, developed by CanSino Biologics Inc. This review aims to examine all animal and human trials conducted for this vaccine candidate. Search terms such as “Ad5-nCoV”, “recombinant adenovirus”, “COVID-19”, and “vaccine”, were used in varying combinations in the PubMed database to find published trial reports. It was concluded that Ad5-nCoV can induce a strong immune response in mice and ferret models and offer them protection against the inoculation of SARS-CoV-2. It also has a strong safety profile in human and can induce an adequate immune response in terms of RBD-specific antibodies and T cell responses, while neutralizing antibody response and seroconversion was mediocre. The publish trial reports support the further testing of this vaccine candidate and it is preparing to enter phase 3 clinical trials.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
