It is found that COVID-19 vaccines increase the immune system, prepare the body to fight against the virus, and reduce the probability of contracting COVID-19.this can be done with the help of regression techniques such as The MAE, MSE, RMSE values to predict and evaluate the observations with more efficiency.
