Federal health officials released Tamiflu for children from the national stockpile and began taking orders from the states for the new swine flu vaccine. The new vaccine, which is different from the annual flu vaccine, is available ahead of expectations. More than three million doses were to be made available in early October 2009, though most of those initial doses were of the FluMist nasal spray type, which is not recommended for pregnant women, people over 50 or those with breathing difficulties, heart disease or several other problems. But it was still possible to vaccinate people in other high-risk groups: health care workers, people caring for infants and healthy young people.

More than three million doses were to be made available in early October 2009, though most of those initial doses were of the FluMist nasal spray type, which is not recommended for pregnant women, people over 50 or those with breathing difficulties, heart disease or several other problems.

本句复杂之处就在于从句里面又套了一个很长的非限制性定语从句，补充说明FluMist nasal spray type（喷鼻型流感疫苗）
