Abstract
To illustrate the dynamics of the COVID-19, we have introduced a mathematical model called PSITPS and shown the effect of protection (vaccination) after treatment.The proposed model solution's positivity, boundedness, existence, and uniqueness are analyzed.The model's possible equilibrium points were also identified, and the Next-Generation Matrix was employed to calculate the Basic Reproduction Number 0 .This study dealt with the stability of equilibrium points at the local and global levels under specific conditions.The Disease-Free Equilibrium point is locally asymptotically stable when 0 < 1; otherwise, it's unstable.By creating the Lyapunov function, we showed that the endemic equilibrium points are globally stable.In this work, we conducted numerical simulations of the model using true data from the COVID-19 epidemic in Najaf.It is a city where religious events abound with large gatherings, which lead to violation of health instructions to avoid infection with COVID-19.The simulation showed that protection (vaccination) after treating the infected had a substantial effect on mitigating the spread of COVID-19.The paper highlights the role of vaccination as a protective measure in effectively controlling the transmission of COVID-19 and mitigating the incidence of illness within the community.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
