RT "nbcnews/health/new-stripped-down-flu-vaccine-might-work-better-study-finds-6C10027328 They only ever admit the imperfections of a vaccination when they are promoting the one that will replace it. "Current flu vaccines are clunky at best. Most are still grown in eggs, an uncertain technology that takes months. Entire factories full of vaccine can be shut down because of contamination. Researchers have figured out how to make synthetic versions of the flu virus to use as a basis for the vaccine, but many still use real viruses, either killed or weakened so they don’t make people sick. And it’s never certain from one year to the next how well the vaccine will work. No one is precisely sure why, but the virus mutates every year, and a variety of strains circulate at any given time. The result is that some years the vaccine protects people well, and in others, it doesn’t.""
