Question

There was no vaccine last summer, and now 70% of people in the United States have received at least one dose of the vaccine. According to CNBC television network, Wall Street Journal, and other media reports, CDC Director Rochelle Walensky said at a White House briefing on the 2nd that the data collected by the CDC showed that the average number of new cases in the United States was 7 days on July 30. There were 72,790 cases per day, higher than the peak of 68,700 cases last summer.

A) True
B) False

Answer 1

The statement about the vaccine coverage in the United States is true, and reflects the significant role of vaccination in reducing the incidence of diseases, as illustrated by historical data on measles. however vaccination doesn't immediately eliminate the possibility of case surges.

Step-by-step explanation:

Based on the information provided and considering the context of past infectious disease outbreaks and the rate of vaccination, the statement that there was no vaccine last summer and now 70% of people in the United States have received at least one dose of the vaccine is true. the comparison to historical data on measles demonstrates the profound impact of vaccination on disease incidence. just as the measles cases decreased significantly after the introduction of the vaccine, so is the expectation with COVID-19.

It is important to notice that even with a high rate of vaccination, there can be surges in case numbers, as indicated by the current average of new cases reported by the CDC. This illustrates that vaccination is a critical tool but not always an instant solution to eradicate a disease. It's also worthwhile to note that the accuracy of surveys and polls related to disease incidence can vary, something that can also be demonstrated by the differences in methodology, population sampling, and other factors influencing the outcome of such research.
