That's about the stupidest question I've seen asked in this forum. Smallpox and polio vaccines are "sterilizing" or "perfect" vaccines. One jab and one receives immunity for life.
The novel, leaky,
unapproved, experimental,
genetically engineered,
chemically enhanced,
innate immune response reprogramming, biological agents neither prevent one from becoming infected by or transmitting COVID. Turned vaccinees into asymptomatic Typhoid Mary carriers and spreaders of COVID-19. In other words Granny killers. And the adverse consequences to immune systems resulting in an increase in cancer and the coming heart failures are only just beginning and will be felt for years. Yet they're not even having difficulty selling morons that lack a capacity for critical thought on boosters.
mRNA vaxx - functional reprogramming of innate immune responses- favoring cancer
This generation of leaky, variant-creating, dangerous, non-vaccines have been responsible for keeping the endemic phase of this virus going, right from vaccine rollout on.
