@The Anointed,
- The jab is not a cure, it is a vaccine.
- No one has ever claimed any vaccine is 100% effective, there are always breakthrough cases although the severity of Covid in the case of a breakthrough is significantly reduced.
- There are close to 4 million nurses in the US so if you have a vaccine that is 90-95% effective (making it an excellent vaccine) there will still be tens of thousands of nurses at risk for a breakthrough, especially if they are exposed everyday. It sounds like the nurse in your example wasn't showing any symptoms though so the vaccine seems to have helped her there.
- It is really weird that a nurse would save her needles as needles are hazardous medical waste and are usually immediately disposed of in special puncture proof containers. Maybe your story is not true as no reputable nurse would save used needles.
