Which of the following explains the impact of the creation of the smallpox vaccine on the Americas?(1 point)
a. It led to the deaths of about 90 percent of Indigenous Americans.
b. It prevented milkmaids on the two continents from getting the disease.
c. It led to the development of ways to prevent the disease like mosquito nets.
d. It led to the complete eradication of the disease
a. It led to the deaths of about 90 percent of Indigenous Americans.
To determine the correct answer, let's analyze each option and find the one that best explains the impact of the creation of the smallpox vaccine on the Americas.
a. It led to the deaths of about 90 percent of Indigenous Americans.
This statement is incorrect. The creation of the smallpox vaccine did not directly lead to the deaths of about 90 percent of Indigenous Americans. The impact of smallpox on Indigenous populations in the Americas was primarily a result of the introduction of the disease by European colonizers, who brought smallpox with them to the Americas.
b. It prevented milkmaids on the two continents from getting the disease.
This statement is not relevant to the impact of the smallpox vaccine on the Americas. The smallpox vaccine was primarily developed to protect individuals from smallpox infection, rather than specifically targeting milkmaids.
c. It led to the development of ways to prevent the disease like mosquito nets.
This statement is also incorrect. The impact of the creation of the smallpox vaccine on the Americas did not directly lead to the development of ways to prevent the disease like mosquito nets. Mosquito nets are primarily used to prevent the transmission of mosquito-borne diseases such as malaria, while smallpox is primarily transmitted through person-to-person contact.
d. It led to the complete eradication of the disease.
This statement is the correct answer. The creation of the smallpox vaccine played a crucial role in the eventual eradication of the disease. The World Health Organization, along with various other organizations and governments, embarked on a global vaccination campaign in the 1960s and 1970s, which eventually led to the complete eradication of smallpox in 1980. This achievement is widely considered one of the greatest accomplishments in the history of public health.
In conclusion, the correct answer is option d. It led to the complete eradication of the disease.
The correct answer is:
a. It led to the deaths of about 90 percent of Indigenous Americans.
