Yes your concern is normal
From my point of view, lack of concern is abnormal. Nobody knows the long term effects of this experiment, safety studies were bypassed because of "emergency", the percentage of adverse effects (including death) is multitudes higher than any other "vaccine".
My testimony: I personally know three people (including my sister) who got the China virus and recovered by fully. I also know three healthy people who have died unexpectedly, two from blood clots, one from a sudden heart problem - all three died soon after their second injection.
The virus is not ffatal for anyone with a healthy immune system,t yet he ssupposed "vaccine" preventative can be fatal. There is no legal recourse for damage caused by the COVID "vaccine" experiment. I
Now that the virus has been circulating for over a year, most people have immunity, no matter what new "strain" our health authorities try to scare us with. If anyone does become sick with a new "strain", ask your doctor about ivermectin. Factually, there is a cure, no matter how many times it is said "there is no cure for covid". This is a lie to get people to participate in their "vaccine" experiment.
