I am not a doctor but I don't recall my childhood vaccinations wearing off after a few months.
Just imagine what it will be like in a couple of months when the weather gets colder and
the flu Covid-19 starts to spike again. We can't be far away from people getting an IV drip of the "vaccine" all day.
Some Catholics go to Mass twice a year. Some go every Sunday. But some go every day. Getting "vaccinated" is a religious ritual for these people and they just can't get enough of it.
Lockdowns. Shortages. Mask mandates. Proof of "vaccination" to travel on planes, trains and busses. It is all likely coming in just a few months so don't squander this time.
