If all goes well, this new shot would last for multiple flu seasons, so you wouldn't have to roll up your sleeve every fall and -- importantly -- it would be more effective than the shot you get now. Way more effective.
That's the day Sonn became one of the first people to receive an experimental flu vaccine that could one day radically change the shot you get every year.Michael Sonn receives follow-up testing after becoming one of the first people to receive an experimental"universal" flu vaccine as part of a clinical drug trial at the National Institutes of Health.While the current flu shot keeps millions of people from getting the flu every year, it's far from perfect.
Seasonal flu: What you need to know 01:46The reason is that the flu virus is constantly changing. Strains that wreak havoc one flu season are gone the next, replaced by strains that maybe haven't been around for years."Flu is really scary and tricky," said Dr. Julie Ledgerwood, chief of the clinical trials program for the Vaccine Research Center at NIAID, which is a part of the National Institutes of Health, and one of several sites around the US participating in the vaccine trial.
Health experts push to change laws on child flu vaccines 02:32The 1918-1919 Spanish flu pandemic infected a third of the world's population and killed 50 million people.Losing his parents at 6 years old left a mark on Sonn's grandfather, and subsequently on Sonn himself."He really had great trust in science and medical research, so I know he would be proud I'm taking part in this," Sonn said.
Don't believe this about the flu 01:21In the meantime, some flu shot manufacturers have taken smaller steps toward a better flu shot.Most of the flu vaccines on the market today are made using chicken eggs -- just like the ones you eat for breakfast. Scientists pick what flu strains they think will attack during the upcoming flu season, put those viruses in the egg where they multiply, and then once they've grown, use those viruses to make the vaccine.
But he added that this approach still requires growing the virus, which is time consuming. The faster and more precise method is not to grow the virus at all and instead just create the virus' protein, he said."We clone the gene that codes for the specific protein we want," Fauci said."I don't even want to see the virus. I just need the sequence of that virus, the genetic map of that virus. And you could send that to me by email.
