I work PT at a place that tests doctors, nurses, etc.. they must re-certify every so often.
Some are saying that the Johnson&Johnson vac is the best. The others have an RNA "adjusting" feature that is mostly untried/unproven, regardless of the press.
the JNJ is a once prick.
If you have family or friends .... tell them to not take the RNA vacs according to some researchers/MDs. Go to the JNJ next year if you took the others this year. Avoid the RNA manipulating vacs.
I have not been jabbed and am unsure if I will be. Had CV in Jan. 2020. It is man-made and it is dangerous. But, you have to be already weak to die from it.
