If NZ ever "opens up" they're going to have increased cases.  This thing is going to bounce around for years, and they haven't given their population any chance at all to start developing herd immunity. 

I don't disagree with their initial plan, we had no idea what this thing really was.  But at this point, they're simply delaying the inevitable. 

The path is determined-- open slowly, manage the hospitals, and move back to normal.

Antibodies also come with an expiration date: Because they are inanimate proteins and not living cells, they can’t replenish themselves, and so disappear from the blood just weeks or months after they are produced. Hordes of antibodies appear shortly after a virus has breached the body’s barriers, then wane as the threat dissipates. Most of the B cells that produce these early antibodies die off as well.

But even when not under siege, the body retains a battalion of longer-lived B cells that can churn out virus-fighting antibodies en masse, should they prove useful again. Some patrol the bloodstream, waiting to be triggered anew; others retreat into the bone marrow, generating small amounts of antibodies that are detectable years, sometimes decades, after an infection is over. Several studies, including those led by Dr. Bhattacharya and Dr. Pepper, have found antibodies capable of incapacitating the coronavirus lingering at low levels in the blood months after people have recovered from Covid-19.

“The antibodies decline, but they settle in what looks like a stable nadir,” which is observable about three months after symptoms start, Dr. Bhattacharya said. “The response looks perfectly durable.”

Seeing antibodies this long after infection is a strong indication that B cells are still chugging away in the bone marrow, Dr. Pepper said. She and her team were also able to pluck B cells that recognize the coronavirus from the blood of people who have recovered from mild cases of Covid-19 and grow them in the lab.
Multiple studies, including one published on Friday in the journal Cell, have also managed to isolate coronavirus-attacking T cells from the blood of recovered individuals — long after symptoms have disappeared. When provoked with bits of the coronavirus in the lab, these T cells pumped out virus-fighting signals, and cloned themselves into fresh armies ready to confront a familiar foe. Some reports have noted that analyses of T cells could give researchers a glimpse into the immune response to the coronavirus, even in patients whose antibody levels have declined to a point where they are difficult to detect.

Scientists See Signs of Lasting Immunity to Covid-19, Even After Mild Infections

New research indicates that human immune system cells are storing information about the coronavirus so they can fight it off again.

• Coronavirus patients who do not require hospitalization can still experience a number of long-term health issues.
• Doctors are already finding that otherwise recovered coronavirus victims tend to experience lingering symptoms such as fatigue, breathing issues, and a host of cardiovascular problems.
• A recent CDC report found that one-third of coronavirus patients endure symptoms that don’t go away.
