That source explains herd immunity; what it is, how to achieve it, etcetera. It also explains herd immunity to Covid 19 in America is possible if enough Americans get vaccinated. It also explains eradication is unlikely because herd immunity and eradication are different.

This source explains why herd immunity isn't possible for colds and the flu and why making comparisons to Covid 19 aren't applicable because the situations are different.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8053397/#:~:text=Also%2C%20during%20the%20same%202018,around%203500%20deaths%20%5B3%5D.
This source indicates the vaccination rate for the flu in American during the 2018-2019 flu season was 49%. As explained in the first source, a vaccination rate of less than 50% isn't high enough for a population to achieve herd immunity especially with a virus that mutates frequently.
Also, the efficacy rate of a vaccine is an average. However, the breakthrough infections occur randomly within the population. For example, if your population is 200 you could have 150 negative tests results in a row then 10 positives within the last 50 and that averages out to an efficacy rate of 95% even though there was a 0% positivity rate for the first 100 and 10% rate for the second 100 or a 20% rate for the last 50. Because that is how averages work, Big Ern.
No one is reading your book reports and the info is likely irrelevent, look how much the CDC and Fauchi flip flop. Covid is here to stay like my original post stated. 25% of cases in LA are now vaccinated. It will mutate down and be much like a common cold at some point in the future.
