COVID-19: Different Strains of Corona, Vaccine Efficacy, Treatment, Medical Ethics, and Future Perspectives

Abstarct: In the pandemic era of COVID-19, there is an urgent need to develop a safe and effective vaccine to prevent different variants/strains of COVID-19. The developed vaccine must have the potency of sustained/controlled drug release into the body. The emergency is reinforced by detailed scientific knowledge in the genomic field, which eases the rapid development of an effective vaccine using novel approaches that enhance large-scale production, manufacturing, and testing analysis. This manuscript concludes the various variants of COVID-19 and types of COVID-19 vaccines available in the pharmaceutical market with their pricing details and even discusses their efficacy against various COVID-19 variants. Global partnerships with other pharmaceutical industries and countries have played a significant role in distributing and deploying the vaccine among the masses. Social support, relaxation exercise, psychological counseling, parents’ role, psychiatrist help, family support, yoga, meditation, exercise, and a balanced diet reduce psychosocial stress and promote health.
