Well, it IS different than the shots we had in kindergarten. A traditional vaccine uses a weakened or dead virus to compel the human immune system into action. These new vaccines (all of them) do not. Why? This issue is what makes most of us "vaccine hesitant" uneasy. Even the more traditional J&J vax uses the Adenovirus (not Covid-19) as it's core mechanism. If Covid-19 is truly a virus than why not use it (in weakened form) as a basis for a vaccine? Honestly, if someone could provide a coherent explanation of this than most of us would be at the vax clinic tomorrow, me included. I have had all of my traditional vaccines and boosters and cannot by any means be labeled "anti-vax".
There is nothing political about this issue for me - I'm a libertarian nutty-crunchy environmentalist with a soft spot for the down and trodden (that includes animals and insects). I'm also a health nut and vegetarian and have been well served by my own immune system for 58 years..haven't seen a doctor in over 7 years and have no intent on seeing one anytime soon. I am also highly suspicious of the pharmaceutical industry and do not take any meds except for the occasional ibuprofen pill to dull the pain of this injury or that.
Something about this whole thing just seems a bit off. It used to be that if you got a disease and survived then you would obtain immunity for a decent length of time. Now "the experts" are saying no, that doesn't apply anymore. So they expect us to believe that thousands of years of human evolution and immunology is no longer valid? Occam's razor.
