There is precisely ZERO data available on the long term effects of these "vaccines" (they are actually experiment gene therapies and NOT vaccines).
The components of the vaccine (the mRNA as well as the spike proteins produced by your cells when they read the mRNA strands) are gone from your system in a matter of weeks. We have people who were immunized with the Pfizer and Modera shots for about a year now from the trials and all of the symptoms manifest in the first few days as the immune system sees the spike proteins and attacks. (Just what the vaccine is designed to do.)
What we do know is that there are quite a few adverse side effects that compromise fertility, cardiac functionality, severe arthritis, nervous disorders, and has even lead to death in thousands of cases so far.
There is zero proof that there is any fertility, cardiac, arthritis, or nervous system impact. This is all just Internet conspiracy theories with zero scientific backing. "I read it on Facebook" doesn't equal scientific proof.
As for the "thousands of deaths," yes, thousands of deaths after vaccination were logged into the vaccine reporting system VAERS. However, there are two important points to remember. First of all, ANYTHING can be logged into VAERS. I could log that, after my vaccine, I turned into the Incredible Hulk. It wouldn't be true, but it would be in VAERS. So data in VAERS needs to be verified before it is used. Secondly, correlation doesn't equal causation. If an 85 year old man with a history of heart disease dies of a heart attack two days after being vaccinated, it will be logged into VAERS. This doesn't mean that the vaccine caused his death, though. More likely, it was his history of heart disease and the vaccine's proximity was just a coincidence. We've given over 300 million doses of the vaccine - a few thousand people dying around when they got the vaccine could be due to pure chance instead of being caused by the vaccine. (And, in fact, scientists looking into this came to exactly this conclusion - the deaths were unrelated to the vaccine.)
Important to remember, none of these vaccines has FDA approval. They only have emergency authorizations. So maybe we should save the fan fair for a couple years until we can breath a little easier that this isn't going to be another "thalidomide" situation on a global scale.
The only difference between the EUA and full authorization is some paperwork. All the trials are done and the data collected. Pfizer and Moderna have both submitted the paperwork for full authorization. They'll likely get the full authorization as soon as the FDA processes this paperwork.
