Getting re-infected by the novel coronavirus could be possible within six months of recovery, according to a new study published by a team in Amsterdam. If that is the case, then Israel’s hope of testing 1 million Israelis for antibodies to SARS-CoV-2 partially to keep the economy open in any subsequent rounds may be shattered.

A team of 13 researchers from the country located in the Western Netherlands recently uploaded a paper to Medrxiv, an internet site that distributes unpublished manuscripts about health sciences, after monitoring 10 subjects who had contracted at least one of four species of seasonal coronaviruses over a time span of 35 years (1985 to 2020). In “Human coronavirus reinfection dynamics: lessons for SARS‐CoV‐2,” they claim that “an alarmingly short duration of protective immunity to coronaviruses was found... We saw frequent reinfections at 12 months post‐infection and substantial reduction in antibody levels as soon as 6 months post‐infection.”

Since there is no treatment or vaccine for the novel coronavirus, or COVID-19 - the disease to which it leads - the only way to stop its spread is through social distancing and good hygiene. As such, long-term protective immunity could impact the overall course of the pandemic, the post-pandemic period and any subsequent waves. Until now, this concept has been a key component of the Health Ministry’s second wave strategy.
The Health Ministry recently revealed that it had purchased serological tests with the aim of surveying as many as 1 million people to determine how much of the public has been infected. Since around 80% of people who get the virus show little or no symptoms, they can carry and spread it without knowing.

However, “serology-based tests that measure previous infections for SARS‐CoV‐2 may have limited use if that infection has occurred more than one year prior to sampling,” the Amsterdam researchers explained.
Relatedly, there has been ongoing discussion about herd immunity, the idea that when a threshold proportion of a population is immune to a certain pathogen this protects even non‐immune individuals against the infection by limiting overall spread. Such a concept has proven effective with a variety of other viruses, including hepatitis and influenza A. However, achieving herd immunity may be challenging due to rapid loss of protective immunity, if the Amsterdam study is correct.

“It was recently suggested that recovered individuals should receive a so‐called ‘immunity passport,’ which would allow them to relax social distancing measures,” the authors explained. “However, as protective immunity may be lost by six months post infection, the prospect of reaching functional herd immunity by natural infection seems very unlikely.”

You want positive?
I think you should wait on that, like the rest of us.
