A student researching vaccines has taken the following notes:
• Edward Jenner developed the first vaccine in 1796 for smallpox • Vaccines work by training the immune system to recognize pathogens • Smallpox was officially declared eradicated in 1980 • The COVID-19 mRNA vaccines were developed in under a year • Vaccines have saved an estimated 154 million lives over the past 50 years
The student wants to demonstrate the life-saving impact of vaccines. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Edward Jenner developed the first vaccine for smallpox in 1796, leading to the disease's eradication by 1980.
Vaccines work by training the immune system to recognize and fight specific pathogens effectively.
Over the past 50 years, vaccines have saved an estimated 154 million lives, demonstrating their crucial role in public health.
The rapid development of COVID-19 mRNA vaccines in under a year marked a breakthrough in vaccine technology.
Correct Answer: C
Choice C. The 154 million lives saved statistic directly shows life-saving impact.
