英国 PepTcell 公司声称,已设计了一个数学程序,能预测/确定在人和动物流感病毒株中60多年没有改变的病毒成分。基于这些保守的、有免疫原性的病毒成分,合成了一组可用于单个疫苗的六肽,此疫苗无需每年改变疫苗成分就可提供抗目前和将来病毒株的长期保护作用。传统疫苗用鸡胚生产,当新的毒株出现时,所用病毒必须改变,从而导致较长的疫苗生产准备时间,且需要猜测在下个流感季节或暴发中的主要 PepTcell, the UK, claims that it has designed a mathematical program that predicts / determines viral constituents that have not changed for more than 60 years in human and animal flu strains. Based on these conserved, immunogenic viral components, a set of hexapeptides was developed for use as a single vaccine that provides long-term protection against current and future virus strains without requiring an annual change in vaccine composition. Traditional vaccines are produced with chicken embryos and the viruses used must change when new strains appear, resulting in longer vaccine production preparation times and the need to guess the major
