There is more coming, but it not coming as quickly as we would like.Gellin said manufacturers have continued to tinker with the efficiency of the production of the H1N1 vaccine, making improvements to the yield, but that global influenza vaccine capacity is largely fixed, due to the number of facilities and the time-tested, but time-intensive, process of growing vaccine virus in eggs.However, one tool for stretching vaccine supply, called adjuvants, has not been employed by the United States in this pandemic.
