Covid-status certificates could lead to deliberate infections, scientists warn

Immunity certification could foster an erroneous sense of no risk' in people's behaviour, according to analysts

Covid-status certificates - to allow those who have been vaccinated, recovered from the virus or have tested negative to attend an event or holiday abroad - could do harm as well as good, UK government science advisers have warned.

While they could encourage some people to get vaccinated, the scientists say others may deliberately go out to get infected, in order to test positive for antibodies and get a certificate enabling them to mix more freely.
