Are Covid 19 recovered people protected from a second coronavirus attack? This is the doubt many have. Well, the World Health Organization has revealed that there was “no evidence” for this.
The WHO in a scientific brief said “there is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.” It also warned governments against giving “immunity passports” or “risk-free certificates” to cured persons. This could increase the risk of spreading of the virus as the recovered people may not follow the guidelines.
The WHO came out with such a warning as some countries pointed out to these certificates for using to travel or go to work. Chile had last week said that they would issue “health passports” who have recovered from coronavirus. It said that they could rejoin the workforce.
The UN Health Agency said that it was continuously reviewing the evidence on antibody responses to SARS-CoV-2 infection. Most of these studies show that people who have recovered from infection have antibodies to the virus, the Agency added.
The WHO said that several countries were testing for SARS-CoV-2 antibodies in humans, especially in close contacts of known cases, health workers or within households. The Agency said that they fully supported such initiatives.
