“CSL -SQirus was negatively influenced by considerably low flu immunization percentages, in particular in the United States,” said CSL Chief Executive and director Dr. Paul McKenzie.
The American Centers for Disease Control and Prevention said in September that flu vaccine recording in the US had slowly increased before the COVID-19 Pandemie, but since then fell to the lowest level in 12 flu seasons for children and six seasons for adults.
CSL Behring, which makes blood derived from blood for people with rare diseases, did much better, with a turnover of 10 percent to $ US5.7 billion ($ 9 billion).
