Some May Get Tiny Needle Flu Shots
September 6, 2011 by staff
The first flu vaccine that works with a puncture in the skin less fear instead of a needle an inch long is going to market this fall. Sorry guys, this option so far is for adults only, and is so new that will take a bit of searching to find a fix.
But there are plenty of other varieties – standard shots, a special high-dose vaccine for older adults and the needle jet nose-choice – for everyone. At least 166 million doses of flu vaccine are expected to occur this year.
The big question is whether people will get it. Usually, the annual flu vaccine varies between earlier versions and the different strains of flu arise. This year, the vaccine is a duplicate, because the three flu strains that people who became ill last winter are still in circulation.
Scientific studies are not clear how much a person’s immunity decreases over a year, although it varies depending on age and overall health. However, federal health officials and the American Academy of Pediatrics weighed the evidence and say no to skip the vaccination this year – that’s the only way to ensure that your immune system is fast enough to keep the best protection.
“We will not be able to expect that the vaccine will protect through a second season,” says Dr. Lisa Grohskopf the Centers for Disease Control and Prevention.
An annual vaccination is now recommended for almost everyone, except babies under 6 months and people with severe allergies to eggs used in their preparation. Last year, 49 percent of boys and 41 percent of adults were vaccinated.
They say you never get the flu? You could be a carrier unknowingly spreading the misery when you feel something more than a cold, says Dr. William Schaffner of Vanderbilt University, president of the National Foundation for Infectious Diseases.
“You should be vaccinated every year to ensure that both you are protected and that you give maximum protection to the people around you,” he says.
Here are some questions and answers about the flu vaccine:
Q: How is the surface the new vaccine efficacy?
A: Fluzone from Sanofi Pasteur, intradermal needle is used less than a tenth of an inch long to inject the vaccine just under the surface of the skin. This layer, called the dermis, is so rich in a type of immune cell that the new vaccine uses a lower dose of the same vaccine that regular flu vaccines. The studies found that led to more protection than any vaccine muscle strength – despite causing more skin reactions such as redness, swelling and itching. There are few data on the perception of pain.
But only for 18 – to 64 years old. It has not been studied in children and skin more tender. Sanofi estimated to sell for less than 1 million doses this year to introduce the new product approved doctors, before launching a full season next flu market.
Q: What about the flu vaccine ouchless original, the version in a nasal spray?
A: MedImmune FluMist is for a group of different ages, people from 2 to 49 who are healthy, meaning anyone with health problems or is pregnant. Unlike influenza vaccines are made with killed influenza virus, FluMist is made with live but weakened virus.
Q: For older adults, the CDC recommended the injection of high doses?
A: The immune system weakens with age; so do not respond as well to a vaccine against the flu. Sanofi Fluzone doses is a standard shot into the muscle and contains four times the usual dose to stimulate the immune response in people older than 65. First sold last year, studies are still ongoing route in the event that results in less illness and hospitalizations. May cause more side effects typical of flu vaccine. The CDC says it’s OK for older people to choose between an injection of high doses and regular injections of a variety of manufacturers.
Q: Who is most at risk from the flu?
A: Young children, anyone over 50 years, anyone with chronic medical conditions like asthma and certain heart problems or kidney disease, and pregnant women. A flu vaccine during pregnancy has the added advantage of conveying some protection for the baby.
Q: When should I get?
A: At any time, but it takes two weeks to produce, protection against the flu usually begins to circulate around November and peaks around January. Some drugstore chains began vaccinating a month. Next month, Hawaii began to offer free school immunizations for primary and secondary students.
Do not get discouraged too long, says Dr. Scott Gorenstein Great Neck, NY, an emergency room doctor whose son Nate, then 4, to die of the flu during the 2009 pandemic. The boy had already been exposed to the vaccine was available last time in the fall. Now, says the whole family Gorenstein inoculated in early autumn – even though Nate has developed an allergy to the vaccine as a precautionary measure and control in the hospital for a dose.
“We were lucky,” says Gorenstein, who now advises a group called Families Fighting Flu. “I just do not want to be a statistic that can be prevented.”
