Coronavirus immunity
Coronavirus immunity may only last six months raising doubts over ‘immunity passports’
The discovery by scientists at the University of Amsterdam has raised questions over whether ‘immunity passports’ could be a route out of lockdown...
Researchers tested 10 men for four coronaviruses, which cause the common cold, regularly over the course of 35 year and found that there was ‘an alarmingly short duration of protective immunity’.
The found that after six months the levels of antibodies had substantially reduced and by 12 months people were frequently reinfected with the virus, The Times reported...
The study, which has not yet been peer-reviewed and did not include women, suggests people may have to get the jab annually to be immune to the bug.

gruesome to think about, but I kind of like the idea:
Cardboard hospital bed transforms into coffin when coronavirus patients die
Rodolfo Gomez, from Colombia, designed the bed-coffin combo after he saw disturbing images of coronavirus victims and other dead people being dumped in the streets of Guayaquil, Ecuador

Then there’s the problem with it mutating. Just because the person may have antibodies for one strain, doesn’t mean they have them for the other dozen strains. That’s why flu vaccines fail so many years.
There have been many studies over the years of the 4 coronaviruses that cause common cold symptoms, all of them showing 6-12 months of immunity. One study showed that after about 6 months, you can be reinfected with HCoV-229E and be asymptomatic, yet still shed the virus at contagious levels. It seems really likely at this point that SARS-CoV2 confers at least 5 or 6 months immunity, and hopefully much longer.
