My husband has a secret crush on Rachel Maddow, so every day he turns on the TV and tunes it to MSNBC, and watches for hour after boring hour. Since my computer is in the living room next to the TV, that means I'm stuck listening to that propaganda mill for hours too. They're still howling about Trump, given any excuse, and at present they're blaming him for the number of people who haven't gotten any form of Covid vaccine yet. *Sigh* As if there were no other reason.
If you go search the Internet for information about vaccination in general, you'll find a much more complicated picture. First, the way a vaccine works is to stimulate the immune system into producing antibodies to a particular bacterium or virus. The more antibodies you have, the better you can fight off the invading microbe. There are two other ways to get those antibodies: 1) get an injection of blood-serum from someone else, or some animal, with a lot of antibodies in their blood, or 2) get the infection and survive it. The antibodies are the whole point.
The problem with vaccines is that there are always some people who have allergies to the growth medium of any given vaccine, which accounts for the cases of bad reactions. Unless your doctor knows in advance just what your personal allergies are, and just what the components of any given vaccine are, s/he can't tell you just which vaccine would be safe for you. If you do happen to have quirky allergies, or don't know what your allergies are, it's best to hold off on getting vaccinated, at least until you know more. If you do know that you have a vulnerability to a particular vaccine, or a group of vaccines, then you have to consider whether you're more likely to die of the vaccine or the disease, and take your chances accordingly.
Then there's the question of the effectiveness of different vaccines, since not all antibodies are created equal. For example, people who received the Pfizer vaccine were less likely to get the Covid infection afterward, but those who did often got a severe form of it -- while those who got the Johnson and Johnson vaccine were more likely to get infected afterward, but always with a milder form. This, BTW, is why Rasty and I held off getting vaccinated until we could be sure of getting the Johnson and Johnson brand.
And then there's the problem of ongoing immunity to mutations and variations of the virus. Given enough time, which the Covid virus certainly has had, any virus will mutate into a distinctly different form. This is one reason why public health services want to get as many people immunized as fast as possible. On the other hand, as our experience with the common flu has shown, an immunity to one form of the virus will usually grant at least partial protection to the next form, so that -- again -- you may get the new infection, but not to a severe degree.
Finally, there's the mystery of how many people have already gotten the disease -- and gotten over it -- without ever realizing that they did. The only way to tell if you're in that category is to get the blood-serum antibody test and see if the antibodies are already there. If they already are, then it's anyone's guess whether taking the vaccine will give you more of them, or have no effect at all; there isn't enough known yet.
In short, there is no one-size-fits-all solution, and shaming/threatening/forcing people to get whatever vaccine is in greatest supply right now, wherever they are, is a serious mistake. It also raises a lot of bad feelings and distrust toward the public health system.
Trump had nothing to do with it.
