Now the cat is really out. The flu vaccine that has been in used this season is just a tad better than a placebo. Placebos are nothing but made of filling materials, without medicinal value and the flu vaccine.
Federal officials this week said this season’s flu vaccine, already acknowledged to be highly ineffective, is performing even worse than earlier estimated, according to HealthjDay, a National Institutes of Health online news publication. First the CDC said it was approximately 50 percent effective, then it was down to 23 percent effective and now it’s even lower than that at 18 percent.
This is the reason why the dominant flu virus strain H3N2 was able to have its way infecting a lot of people.
And you will be shocked to know is even much lower for children who are the most susceptible to flu at only 2-8 percent. The injected vaccine is only at most 15 percent effective for children the Centers for Disease Control and Prevention said in a released statement.
Even worse, the nasal spray vaccine has zero effect on them, it said. “Neither vaccine worked well in protecting against H3N2 viruses this season” for children, it said.
Upon evaluating the new data, the CDC cancelled its support for the recommendation of nasal spray flu vaccine for children. It will come up with another recommendation who could use the spay this coming flu season in June.
“The decision not to renew … was made based on new data from more recent seasons which have not confirmed superior effectiveness of (the nasal spray) observed in earlier studies,” the statement said.
The advisory panel of CDC continued its support for a flu vaccine for healthy individuals six months and older.
The CDC explained that the flu vaccine has a effectivity rate for different age group. These are, for those ages between 18 and 49, its 18 percent effective. Individuals 50 years old and above it’s only 14 percent. How they came up with these data is not clear however.
Flu vaccine effectiveness has ranged from as low as 10 percent to 60 percent or better, CDC said. It did not say when the effectiveness rate was this close to the low end, although it has been measuring effectiveness since the 2004-2005 flu season.
Flu vaccines have been performing from as low as 10 percent to as high as 60 percent according to the CDC. It didn’t mention when these figures were taken. The CDC has been monitoring the effectivity rate of the flu vaccine since the 2004 and 2005 flu season.
The excuse given for the poor performance of the vaccine is that it did not match the virulence of the virus strain creating havoc this year. Over 66 percent of the H3N2 virus in circulation are much stronger than the available vaccines, CDC said
“We knew it wasn’t the best vaccine in history, and now we have data,” said George DiFerdinando, adjunct professor in the department of epidemiology at the Rutgers School of Public Health.
