I should not have written "Vaccines were never expected to stop the pandemic." Vaccines were expected to stop the pandemic.
PRC, Hong Kong, Taiwan, and other countries had SARS-CoV-1 in 2003 [0]. It kills 9% of people who catch it, even young people. Their governments performed effective contact tracing and forced quarantining. Everyone in those countries was careful not to catch or spread the disease. It nearly became a pandemic, but the people stopped it.
I hoped that Americans would do the same with SARS-CoV-2 (covid).
Instead, we went half the pandemic without a pandemic expert (epidemiologist) on the National Covid Task Force [1]. Our national leader downplayed the pandemic, refused to be careful not to catch or spread the disease, caught the disease, exposed his political opponents to it during debate, recovered, and consistently undermined and contradicted our national pandemic experts (CDC) [2].
Our government contact tracing programs have been underfunded and ineffective. Only schools performed effective contact tracing. Quarantine is not enforced or even checked. There are no fines or prison time for sick people who go to work or to gatherings and spread the disease.
Many Americans refused to take simple precautions to avoid catching or transmitting the disease. Some places even banned such precautions [3]!
About 20% of adult Americans refused the vaccine [4].
Americans refused to cooperate and achieve herd immunity. Do not blame epidemiologists for telling us what was possible. We should blame callous & incompetent politicians for undermining our medical professionals, blame callous & greedy media companies for targeting medical advice with their anti-establishment dogma, and blame callous & gullible Americans for refusing vaccines and carelessly spreading the disease.
Cities with cooperative people did achieve herd immunity. For example, San Francisco did in 2021-06 [5].
Then Delta and Omicron variants arrived. They break through existing immunity. USA now has 700,000 new cases of Omicron per day [6]. So we should reach herd immunity for Omicron in March. Then the pandemic will be over for us, unless another breakthrough variant arises.
