What if COVID-19 is forever a pandemic?

What are the chances that not enough Americans will be vaccinated to reach that 80% goal to end the pandemic of COVID-19 to get our lives back to normal? Also, what if the supply, and demand of Pfizer, Moderna, and Johnson & Johnson does not rollout fast enough to get enough people vaccinated or inoculated anytime real soon if ever? What if the variants go wild so our lives will seemingly never return to normal? We’ve got problems! Then what happens next if we don’t reach 80% herd immunity? What if we have 200 million American deaths? What if we live in COVID-19 as a pandemic for 20 years or longer?
