It’s an interesting question and I don’t think anyone really knows. Here are a couple of thoughts:

1. Most of this info has been purged - but typically it took 10 yrs if not longer to do a conclusive study and then sometimes longer to determine side-effects of a new vaccine.
2. Because of the timing from development to production, the truth is we don’t know what the Long term effects will be.
3. There have been some really good studies out there that show the vax is bad. We know that it tricks immune systems to keep producing the viral shell and in turn it continues to trigger an immune system response. We also know that the vax was a bio weapon developed in China and funded by us.
4. Why would we (see darpa whistleblower on project Veritas) develop a vaccine based on a bio weapon that reproduces a known bio weapon to further elicit the same response in our body?
5. We know there is some bad stuff in the vax that probably should not be there. At best this was cutting corners to produce a vax in a hurry and at worse is something far more sinister.
6. I think you are right, we have seen many of the reactions occur in the first 6 months of taking it. This first reaction should have been warning enough that something was wrong.
7. What we don’t know is whether the vax dies off or will cause long term damage. I believe the vax has acted as an accelerant for other conditions that may not have manifested. Note the high number of cancers and other chronic illnesses that seem to be emerging. Also consider enhanced susceptibility to other common diseases which happens when one’s system is immuno compromised.
8. Not to doom, but I don’t see a way where many more fools become permanently damaged due to the vax. A key component of any condition is time, and as time moves on we will see more adverse reactions develop that could have been avoided.
9. Ending on a hopeful note - I do believe that God creates the human body to be resilient. Life finds a way. If someone took a vaccine unwittingly they still have a strong chance of beating the effects. The one thing everyone should stop doing is taking boosters, as just like a exponential multiplier, boosters remove any chance your body has of beating this.

Hope this helps. Cheers.
