Question

the impact of vaccinations on global public health by dr. emily chen, md, mph. vaccinations have revolutionized public health over the past century, dramatically reducing the incidence of many deadly diseases. according to the world health organization, immunization currently prevents 2 - 3 million deaths every year from diseases like diphtheria, tetanus, pertussis, influenza, and measles (who, 2023). one of the most significant achievements of vaccination has been the global eradication of smallpox, declared in 1980. this success has inspired ongoing efforts to eradicate other diseases, such as polio. the global polio eradication initiative reports that polio cases have decreased by 99% since 1988, from an estimated 350,000 cases to 33 reported cases in 2018 (gpei, 2023). vaccines work not only by protecting individuals but also by creating “herd immunity.” dr. paul offit, a renowned vaccine expert, explains, “when enough people in a community are vaccinated against a disease, the entire community is protected because the disease has little opportunity to spread” (offit, 2021, p. 42). however, maintaining high vaccination rates remains a challenge. the recent covid - 19 pandemic highlighted both the critical importance of vaccines and the complexities of achieving widespread immunization. as dr. anthony fauci noted, “vaccines don’t save lives. vaccinations save lives” (fauci, 2022, p. 456). which of the following research questions would be most effective in exploring the connection between vaccination and vaccine hesitancy? a. how many people have been vaccinated in the last year? b. what are the most common misconceptions people have about vaccines, and how can these be addressed? c. what diseases have been eradicated due to vaccination? d. how much do vaccines cost in different countries?
