Today's vaccines are different than those of even 60 or 70 years ago and before. The old vaccines probably did exactly what they were supposed to do. They sent in a "dead" virus, which activated the immune system against the live ones.
Today's vaccines are extremely potent. The potency doesn't have much to do with the particular virus involved. Rather, because of all the toxins and poisons in today's vaccines, they probably don't need the dead virus at all. Rather, the immune system takes one "nibble" of modern vaccine substance, and goes into "rabid" overdrive, lashing out at anything and everything.
That's why we are getting all kinds of autoimmune diseases from the vaccines. That's where essentially all the ADHD, autism, MS, and over 100 other autoimmune come from. On top of that, the shock of the system going into overdrive, often does neurological and mental damage to the recipient (victim). The dumbing down of the patient is similar to that done by many illegal drug overdoses.
So, there are probably benefits from some vaccines. But multiple vaccinations of different standard vaccines is really a dangerous thing. And the fact that the medical is starting to come out and admit that they don't know for sure which saves more lives, vaccination or no vaccination, is major point that should actually place all vaccinations on hold until the safety studies are completely finished on them (The Robert Kennedy, Jr., answer -
