COVID-19 time is a great time to assess human sentiment when it comes to resistance that was observed to get vaccine administered in USA. There was large amount of hesitancy bordering on hate to get COVID-19 vaccine and it has blown into a public health challenge. In this paper, we investigate the resistance that was observed during the initial stages on the Vaccine administration in USA from 2021. We will see there was a large demographic group leading into the year indicating that they will resist to get a vaccine, and they remained unchanged for large period of the that year. To every one surprise, the largest group which resisted the vaccine was the age group between 18-24 (27%) and when it comes to race, Blacks resisted the most (20%). Also, we also saw there was more resistance from the east coast with the west coast more inclined to get the vaccine. In this paper, we will show why there was this resistance and try to make sense why the efficacy of the vaccine took such a long time to get the epidemic and population agreeable to vaccine.

COVID-19 vaccination has been reported to have had some side effects or abnormalities. These abnormalities have been reported after 1 - 2 years after the first dosage. In this paper, we want to investigate if this is true in Indian Population using the Indian Health Authority (IHA) data from January 2022 to December 2022. From this database, we selected a sample data which is a portion of the people living in the great of city of New Delhi. All the sample data contained adults who are > 18 years of age and were either vaccinated or unvaccinated (Sample size n = 11,341,189). In the abnormalities, we particularly want to study if there are any changes to iron deficiency in women particularly as Indian women suffer from low Iron naturally. From the results we found out that the abnormalities after a 3-month period after the vaccination were higher than those in nonvaccinated patients. COVID-19 mRNA vaccine was associated with this new development of nutritional anaemia and aplastic anaemia which were detected in the sample study. The risk of other abnormalities like coagulation defects were also increased after the vaccination and there was also no other risks mRNA vaccine and other viral vector vaccine. We conclude that COVID-19 vaccination did increase the risk of anaemia furthermore than it was before. We find that, education, accessibility of more nutritional food and vitamin intake is the solution for the people suffering from anaemia due to vaccine administration.
