I don’t know about the rest of Europe, but Anders Tegnell himself was convinced that there would be no second wave in Sweden because of Sweden’s many infections in the first four months of the pandemic and the alleged level of (herd) immunity in the country. And for the past month or so, he has been busy telling his compatriots that it was a European, but not a Swedish problem. Europe had a second wave, Sweden didn’t.
An example:
STOCKHOLM, Oct 15 (Reuters) - Sweden reported 1,075 new coronavirus cases on Thursday but the country’s top epidemiologist said a recent rise in new infections was not the sign of a second wave.
Sweden, which has shunned lockdowns, leaving most schools, restaurants and businesses open throughout the pandemic, has seen the number of new cases trending higher since early September.
Many European countries are re-introducing restrictions to prevent the COVID-19 spread after a spike in transmissions. State Epidemiologist Anders Tegnell said countries like the Netherlands, France and Spain were experiencing a second wave but this was not the case in Sweden.“That would take a rather substantial spread in large parts of society that we are not at all seeing in Sweden,” he told reporters, adding however that the recent increase in cases needed to be taken “very seriously”.

Asked about a second wave later, when the numbers in Sweden continued to rise, Anders Tegnell declared that it wasn't important what you call it. However, he didn't hesitate at all when declaring the condition in the rest of Europe a second wave.
