Since December 2019, the world has been under emergency due to novel coronavirus disease (Covid-19). Due to a lack of powerful preventative strategies (such as vaccinations) and pharmaceutical treatments, various preventive techniques have been implemented worldwide. Boosting the immune system is one of the most popular tools which has gained worldwide attention. However, the general public's impression is tainted by a lack of understanding of immune-boosting strategies and timetables. We carried out questionnaire-based research in India to assess people's actual knowledge of immunity and immunity-boosting techniques. The data analysis highlighted the idiographic convolutions in comprehending the various essential aspects affecting these people's immunity perception. The findings show that the general population understands the need to have a healthy immune system to combat any disease. More focus, however, is needed on false immunity-boosting claims and the careful implementation of immunity-boosting methods with professional advice. The study has the potential to address bottlenecks in reaching sustainable development objectives, notably United Nations’ sustainable development goal three, which is Health and Well-being. Ensuring healthy lifestyles and encouraging well-being at all ages is critical to long-term development. The world is currently experiencing a global health catastrophe causing human distress, undermining the global economy, and upending the lives of billions of people worldwide.
