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 dont save lives. vaccinations save lives” (fauci, 2022, p. 456). if you wanted to find peer - reviewed studies on the effect of social media on vaccine hesitancy, which source would be the most effective? a a youtube video explaining the importance of vaccines b a general wikipedia article on vaccine hesitancy c a study by brown et al. (2021) published in nature, discussing the link between social media and vaccine hesitancy d a news article summarizing a recent public health survey

Explanation:

Peer - reviewed studies are published in academic journals after being evaluated by experts in the field. A study published in a reputable journal like Nature (option C) is peer - reviewed. A YouTube video (A) may not be peer - reviewed, a general Wikipedia article (B) is not peer - reviewed as it is collaboratively edited by users, and a news article summarizing a public health survey (D) is also not a peer - reviewed study.

Answer:

C. A study by Brown et al. (2021) published in Nature, discussing the link between social media and vaccine hesitancy
