After reading this thread, I thought a few points should be made:
-Regarding profits......J&J has stated it will not take a profit for their vac during the pandemic. I don't know if that means they may develop a profitable seasonal/booster shot or profit some other way. But currently...no profit. Also, what is wrong with profit? There are companies that invested $$$ in developing vaccines that turned out not to work. Unless you are for reimbursing the companies that lost money on COVID vac, don't complain about the ones that are making money. Unless you are for that reimbursement, while still complaining about profits, your argument logically leads to only one conclusion....that Pharma should be required to develop vaccines for charitable purposes.
-Regarding the guy who said he had chicken pox, measles, and a few others as a kid and was fine...you did not get polio, malaria, small pox or pin worm as a result of public health measures. The logical thinking is not just what you ailment you got, but what ailments you did not get.
Regarding booster shots....The latest data, yesterday, is that the Pfizer and Moderna vac offer very good protection for AT LEAST 6 months. We simply don't know beyond that, as basically nobody had been vaccinated longer than that. So please, don't make-up the booster shot need/schedule. We simply don't know.
To anyone from Pharma reading this. Thank you for quickly developing safe and highly effective vaccines. I hope it makes you wealthy, and at the same time is fairly and equitably distributed, your work is of huge service to society and is, without question, a net contributor to the economy.
I do think a large number of people will decline the vac. I also speculate that these people are more likely to have been infected with COVID. In trying to the do the math to get to the roughly 80% for herd immunity, there must be some allowance for those people. I know at least 3.
