Polio was not studied "for years" before being administered. I was in the group "polio pioneer's" (I still have the polio pioneer card they gave me). Was done when I was in 1st grade in the gym of my school in early 1950's.
1.3 Million 1st, 2nd and 3rd grade children were enrolled in the
study trial.
Not my card for obvious reasons but sample below:
Anyway, as far as blood clots, it is estimated that 900,000 blood clots happen in the US per year. So That’s about 2500 per day — background noise.
So what's up to the heath authorities in risk assessment is to determine of the 6 cases of bloods clots observed after receiving a J&J shot how many can be attributed to background noise i.e., .how many would have happened normally in the course of just being live and how many are attributed to the vaccine.
And you are correct "6 months of trial studies does not guarantee a safe, effective, consistent vaccine.", but pretty damn close to being safe and effective. But thinking of it this way, waiting for, say, an extra 6 months of testing would certainly result in many hundreds of thousands of deaths from COVID, just in the US, and would continue to wreck our economy.
What you are seeing now is the psychological misestimating risk. For example my sister drove up from Florida to NY because she thinks that the risk of dying in an airplane crash is higher than the risk of dying in a car crash whereas the exact opposite is true.
I, my SO, my friends and relatives all put their big boy pants on and got their shots as soon as they were able to get an appointment.
Polio vaccine was studied for a little over a year (February 1954-April 1955) with a 60-70% success rate at onset of inoculations.
After vaccinations were given there was an outbreak in summer of 1955 due to a bad batch and some 200 cases were reported and attributed to this bad batch.
6 additional months is an eternity in clinical studies for a quick fix type of cure in regards to a viral pandemic. Polio 1 year of studies, COVID 6 months.
I'm not debating the pros and cons of vaccinations, I am simply saying that 6 months of trials is not enough time to gather enough data on a vaccine. Hence the recent "pausing" of the J&J vax.
Nobody knows what any of these vaccinations carry down the road because of the lack of study time - That is a fact, not a political statement.
The NIH will manipulate data and statistics to get the vaccines started by the Pharmaceuticals who get paid lots of money to produce the vaccines. In turn, those Pharma's cram it down physicians throats because the more they vaccinate, the more money the pharmaceuticals and NIH make. The NIH manipulate data to their own benefit just like insurance companies are doing it now when people pass from COVID. The more COVID deaths, the more money they and hospitals can claim.
I am not trying to turn this political, I wish every good person to be well and safe. The majority of us have been impacted by this in some way. Whether enduring it (as I did) or having people in their lives pass from it.
Lets hope this is the only negative regarding these vaccines and we get passed all this.
