That depends.... if I'm told by "experts in the field" that there is potentially a scientifically plausible likelihood of a side effect to giving the "Foot & Mouth" vaccination to my cows and heifers, so that it MAY render them unable to settle/carry a calf, ... possibly ever, if the "vaccine immune response" lasts a lifetime, but because the vaccine developers haven't had enough time to test this concern out yet, nobody knows if this concern, and others, are justified or not..............then no, I wouldn't give the vaccine to my cows..... and I certainly wouldn't give or recommend a vaccine with these potential concerns to my children, or take it myself (I'm old enough to be beyond my prime "child-bearing years").
That's what we're dealing with on ALL of these Covid vaccines. If after long term testing to determine the validity of this concern in your Foot and Mouth disease example, it were verified as justified, then what would be the point of vaccinating my cows/heifers? It'd be the end of my herd either way... if I can't get a calf out of her, she's losing me money and HAS to go down the road... if every cow and heifer is "required" to get the vaccination, but they won't be able to produce a calf, we no longer have a cattle industry. The only farmers and ranchers then that would have beef to sell would be the ones that had been brave enough to say "no" to the vaccine, closed and isolated their herd, and rode it out till the threat of the "pandemic" had passed.
I want to make it clear... nobody knows if this and other concerns about these Covid vaccines are valid or not. The only thing they've tested for so far is whether or not they're effective against the Covid 19 virus. But it has been raised by "medical scientists" with respected careers steeped in virology... people who have been considered "experts" in this field... with no political or financial motive for raising it, as far as I can tell. I suppose that if you happen to be past "child bearing age" anyway, this particular concern might not be something alarming for you directly, and so it might be easy to dismiss it as unimportant, and clearly then not as important as "staying alive" (for which, incidentally, you have a 99.9% chance of anyway without the vaccine, unless you have significant pre-existing conditions which render you "more vulnerable")... but what about for your children, or for the "general population"? Without a "next generation", we're sunk as a nation. If you're concerned for the future of our nation, we certainly wouldn't want to take that risk..................... and certainly, we wouldn't want to encourage the general population to be making decisions with this kind of potential impact on their lives, WITHOUT informing of this potential concern, and WITHOUT the ability to give them thoroughly tested and reliable answers to these kind of important questions, BEFORE they volunteer to take it. Right now, they (the powers that be) are just pushing this thing forward with NO short term OR long term testing, and WITHOUT warning of "potential concerns that have been raised" about it. "It's been approved by the FDA in an "unprecedented emergency use" situation. There's no way that they even COULD have answers to these important questions, because they've not had the time needed to test for "undesireable outcomes or impacts".
But if the public is scared senseless to the point of literally being petrified, holed up in their homes in isolation in fear, they'll jump in line blindly regardless, frantically grasping at the first straw that comes their way, because they've been terrified by the propaganda machine. That's the very definition of "terrorism". And we're operating in panic mode. FEAR is an incredible motivator, and those in positions of power and influence recognize that. The only way that it works though is if WE let it work............. WE do still have the power to CHOOSE NOT PANIC, to maintain our individual freedom, and to use our reason.
Step back, take a breath, .... "Be still, and know that I am God", Ps. 46:10.................... "Fear not, for I am with you; be not dismayed, for I am your God. I will strengthen you, yes, I will help you, I will uphold you with My righteous right hand." Isaiah 41:10 He IS still in control.
