From late 2020 amidst a surge in cases, new legislation was passed enacting international travel restrictions and again limiting participation in public events, banning nursing home visits and closing upper secondary schools. Primary schools remained open throughout the pandemic, and face masks were not generally recommended for the public or in healthcare settings. Vaccinations in Sweden began in December 2020. Spring 2021 saw a surge of the Alpha variant of the virus, and further tightening of restrictions and recommendations. In late 2021, vaccine passports and other measures were introduced. On 9 February 2022 almost all regulations and restrictions were abolished, and from 1 April 2022 COVID-19 was no longer classified as dangerous to the general public or society at large (although reporting requirements stayed in place).
