An immunity passport is an official document that certifies “an individual has been infected and is purportedly immune to SARS-CoV-2.” In principle, this can then give an individual more freedom to travel and socialise, allowing people to enter a country if they can provide evidence that they have already recovered from COVID-19.
The theory is that by providing proof of a positive and then a negative test, the person will have had the disease and is expected to have developed antibodies or other forms of immune memory to protect them from getting ill again.
Hungary has introduced a policy allowing people to enter the country if they can provide evidence that they have already recovered from COVID-19. Iceland is planning on introducing a similar policy that will allow people who have already had COVID-19 to be exempt from the nationwide mask mandate.
This raises difficult questions as some people with underlying health conditions, including autism, panic disorders and breathing difficulties, are already exempt from wearing a mask but have not necessarily recovered from infection or have any immunity to it.
In April, the World Health Organization (WHO) cautioned against the use of immunity passports saying: “there is not enough evidence about the effectiveness of antibody-mediated immunity to guarantee the accuracy of an ‘immunity passport’ or ‘risk-free certificate’.” It recently confirmed that this position has not changed.
WHO also suggested that immunity passports could in fact increase the risks of continued transmission, because those carrying one would ignore public health advice about physically distancing. COVID-19 Vaccine Passport/Certificate
Immunity passports also raise ethical issues due to concerns that documentation could be fraudulently reproduced, and could even incentivise otherwise healthy people to “willfully seek out infection” so they could enjoy more freedom.
