You're correct, it could be an anomaly. It could just as easily be related to vaccine side effects, we don't know for sure, and that is the problem.
There is not enough information available to be forcing people to get vaccinated. If a person does their own research and talks to their doctor, and then decides the benefits outways the risks we know of as of now, that is their choice to get the jab.
Likewise, if a person would rather wait for the clinical trials to finish in 2023 and get a better understanding of all the risks, short term, and long term, that is also their choice not to be inoculated.
The government should not be involved and mandating it.
Remember, every drug or vaccine ever removed from the market for being unsafe or dangerous was once approved by the FDA and CDC as safe and effective.
