As COVID-19 spread globally, the nation of Sweden opted not to institute a strict lockdown policy. Instead, its citizens were encouraged to social distance, and businesses remained open. Their goal was to achieve herd immunity, and as of mid-May in 2020, 7.5% of residents in Stockholm (as a sample of the country) had been exposed to the virus and produced antibodies. These results show that Sweden achieved herd immunity by mid-May 2020.

True or False

False. While a portion of residents in Stockholm had been exposed to the virus and produced antibodies by mid-May 2020, experts have stated that Sweden did not achieve herd immunity at that time. Additionally, the strategy of not implementing a strict lockdown has been heavily debated and criticized by many experts and healthcare professionals.
