ps-as anyone who passed fourth grade science knows
the bacteria in vaccines are either dead, or attenuated. They cannot cause any infection.
It amazes me that the science deniers cannot grasp that simple fact.

Understanding How Vaccines Work
www.cdc.gov/vacci...
Live, attenuated vaccines fight viruses. These vaccines contain a
version of the living virus that has been weakened so that it does
not cause serious disease in people with healthy immune systems.
Because live, attenuated vaccines are the closest thing to a
natural infection, they are good teachers for the immune system.
Examples of live, attenuated vaccines include measles, mumps,
and rubella vaccine (MMR) and varicella (chickenpox) vaccine.
Even though these vaccines are very effective, not everyone can
receive them. Children with weakened immune systems—for
example, those who are undergoing chemotherapy—cannot get
live vaccines

All vaccines create immunity by introducing a substance that triggers the body's immune system to react and produce antibodies, but not all vaccines are the same. Some are made with live viruses or bacteria that have been greatly weakened. Others are made with bacteria or viruses that have been killed. And still others use only specific parts of the bacteria or viruses to stimulate the body's defenses.
Here are the basic types of vaccines:
Attenuated vaccines are made from live viruses and live bacteria that have been weakened, usually by repeated replication in a lab. Because these organisms are alive, it's possible for them to cause a very mild form of the disease. This happens very rarely, but that's why doctors are cautious about giving live vaccines to anyone with a weakened immune system, such as someone being treated for cancer.
These vaccines work by injecting live viruses and live bacteria , weakened but live .
The person with a normal immune system can handle the infection , can take care of the infection before it gets out of control . Unfortunately there are people with a weak or nearly non functioning immune systems , if they are injected with the live viruses and or live bacteria , even in the weakened state , they may not be able to beat back the infection , the live viruses and or live bacteria , even in the weakened state , may thrive in the person with weak or nearly non functioning immune system .
The Attenuated vaccines can and do infect people , in a small and helpful way in people with good immune systems .
The Attenuated vaccines can and do infect people , in a large and damaging way in people with bad or damaged immune systems .
