It created a certain amount of alarm at the beginning of its spread, which led several Member States to make substantial investments in vaccination programmes that turned out to be excessive, because in countries such as Poland, which did not take any exceptional measures, the mortality rate remained at the level of those countries that embarked on national vaccination campaigns, with costs estimated at many millions of euro.
