I did some research on the item posted by the OP and traced it back to an outlet called "The People's Voice" which is a fake news site spewing misinformation.

For further information on self replicating or self-amplifying mRNA components visit the following:

There is no mention of the effects of these vaccines being able to spread from person to person as far as COVID vaccines are concerned, but that does not mean that there might not be attempts to develop such vaccines in the future but I did find an item reporting scientists attempting to develop self-spreading vaccines of other types and though they may not be COVID vaccines, I still don't like the sound of the methods they are using.

Knowing from experience ..
Life's lessons ..

I think we all need to think deeper .. After having children getting their FORCED jabs .. EVERYONE was told .. your child CANNOT BE AROUND ANYONE THAT IS PREGNANT .... fact ... (Measles Vaccines?)

WHAT WAS THE FEAR ?
WHAT WAS THE FACT ?

This distance from pregnant women was for about 2 weeks ... GOOD luck trying to find the details on this FACT ..

People with Neurological disorders have been TOLD .. stay away from those who just took the jabs ... AGAIN good luck finding that fact ...

God bless Robert Kennedy, Jr. because he is going TO CLEAN AND GUT our medical field ...

HOW TO MAKE US THEIR CASH COW .... never to heal .. ONLY TO MAKE US SICKER .. MORE MEDS... MORE HOSPITAL VISITS .. billions spent TO MAKE YOU THEIR CASH COW ...

Have you noticed just how one med leads to another ... Most elderly are taking at least 10 Rx's a day .... and some many more ....

AGAIN ...NEVER ANY HEALINGS ..... why is that ??

How the hell are these people not swinging?

Those who have been jabbed are already shedding. Some of us who are having reactions to it is our body trying to get rid of it.
