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, measles, 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. 56).
in the articles provided, which would be most reliable for data on the global impact of vaccines?
a. a report from the world health organization (who) on immunization coverage (2022)
b. a podcast episode from a well - known celebrity doctor expressing opinions
c. an opinion piece from a local newspaper that does not reference scientific studies
d. a blog post from a vaccine - sharing personal story

Explanation:

The article is discussing the global impact of vaccinations and mentions data from the World Health Organization (WHO). A report from a reliable source like the WHO would be a credible place to find such data on vaccination coverage and impact. Other options like a podcast episode, an opinion - piece, or a blog post from a reactive advocate are less likely to provide comprehensive and reliable data on the global impact of vaccines.

Answer:

A. A report from the World Health Organization (WHO) on immunization coverage (2022)
