Coronavirus immunity: What do we know?

Synopsis

Sweden opts against a lockdown during the COVID-19 pandemic, leading to scrutiny over its strategy to achieve herd immunity. Observers note that this approach results in one of the highest per capita death tolls in Europe, raising questions about the effectiveness of the Scandinavian model. Six months into the pandemic, uncertainty remains regarding the duration of immunity following infection. A recent study indicates significant drops in antibody levels within months after contracting COVID-19. Monica Jones discusses the controversial concept of an immunity passport, which could indicate whether individuals have recovered from COVID-19 or been vaccinated. This idea faces opposition due to concerns it may encourage people to seek infection for greater freedom. Health Minister Yun's bond supports the idea despite the debate, highlighting the need for citizens to know their immunity status. Meanwhile, countries like Iceland consider alternative measures, such as requiring negative COVID-19 tests for entry, rather than implementing compulsory immunity passports.
