It says that the ' effectiveness', of the vaccines can drop to 20% after 5 months or so
If you understand about vaccines, that's the weirdest statement .
The vaccines effectiveness drops????
WTF???
Vaccines mimic the virus. And triggers an antibody production response from your immune system.
And that antibody count goes back down towards zerro over time.
THAT IS NORMAL. For all vaccines.
They make it sound like, that's bad.
But your immune system has a ' memory '
And it's this memory is what stays with you for life.
