That isn't what the pharma companies claim. No vaccine is 100% effective, and it reduces the health of the victim, hence the 5 week wait for the body to regain natural immunity.

Every person exposed to the virus will become infected to a certain degree. The real question is how their bodies will react. Healthy people with strong immunity will shrug off the virus. Vaccinated people will have more problems, and may allow the virus to mutate, as the vaccines are based on unnatural synthesised viruses of virus particles.
