2020.04.17 SARS-CoV-2 study on rhesus macaques seems to show at least limited immunity.

❝ In this preprint, Bao et al. investigated acquired immunity to. Four rhesus monkeys were infected with SARS-CoV-2 and two were reinfected after confirmed recovery. After primary infection, viral replication was detected in the nose, pharynx, lungs and gut, with histopathological evidence of lung damage. Sera collected from recovered monkeys before reinfection exhibited neutralizing activity against SARS-CoV-2. Upon reinfection, viral replication was not detected in nasopharyngeal or anal swabs, and reinfected monkeys did not show any signs of COVID-19 disease recurrence. This suggests that immunity acquired following primary infection with SARS-CoV-2 may protect upon subsequent exposure to the virus. ❞

Immunity and COVID mutation rate
There's some dispute on the Coronavirus mutation rate. The basics are it is an RNA type virus, that's twice as complex and mutates at half the rate of the seasonal flu. Combined, that's an effective mutation rate at 1/4th the Flu. Is that slow enough that we can create vaccines? We aren't sure yet. We think so. But some Chinese researchers dove deeper and found more mutation and outcomes than expected. So need more info. On the other hand, there seems to be evidence in at least limited immunity (plasma/antibody treatment, low re-infection, and study on monkeys). Also there were a few stories about China or Korea finding patients who had been cured that later tested positive. But it is believed that it's just residual RNA fragments that haven't been flushed from the body yet. (Nothing to worry about).
COVID Studies
Antibody tests are proving that continuing lockdown is senseless, and that we are completely being lied to about the denominator (how many total cases there are), which inflates the death rate and scares people unnecessarily.
