What about tetanus, hepatitus, and other vaccines that have booster shots, are those all just cash cows too?
As I see it there are two basic possibilities. Either:
A. Vaccine boosters are just a cash grab
B. They actually work and are necessary to maintaining resistance.
Having a profit motive inevtiably raises the question of whether it is being done for money but it doesn't automatically mean the intentions are profits over people's wellbeing. But do we assume negative intentions about everything?
Are gun practice suggestions just a ploy to sell more bullets?
Are tire wear marks just a ploy to sell more tires?
Is testing your smoker every month a ploy to make them wear out faster or to sell more batteries?
Etc.
I've received tetanus, malaria, hepatitis, and other vaccinations, as well as boosters, but with the exception of getting them in the military when traveling to areas at high risk for such diseases, the OPTION to get vaccinated was MINE. There are lists of recommended shots travelers should CONSIDER GETTING when going to these particular regions. They don't force you to take them or restrict your freedom of movement if you aren't vaccinated.
Therefore, we can pretty much call your analogies and comparisons "Apples vs. Oranges." Those vaccines are completely unrelated to the current COVID vaccination rules of engagement.
Boosters are another Red Herring. So few major disease vaccinations require boosters every 3-6 months like COVID. Even the annual flu shots are NOT boosters. They are RE-VACCINATIONS that are no different than what a first time shot consists of. In all the times I received the flu shot, I NEVER ONCE received a "booster." If it was happening, they would have needed to know when I had my last dose. was never asked, and they never bothered to check.
Tetanus needs a booster after 10 years unless you are injured on rusty metal or other object that might put you at risk. When I go to the doctor, they look up the last time I had a booster, and don't bother with another when they see I was cut by a piece of metal or stepped on a nail the past decade. Therefore, even if you get this booster, you need another shot if you get injured just to be safe. Again, apples to oranges. The COVID vaccine to my knowledge is not being administered to anyone who may be/is infected, but for tetanus, they do that.
The vaccines for COVID are new technology. Comparing them to what other vaccines require and do not require is pointless.
