Skin Patches Could be a New Era in Vaccine Against Pandemics

pandemics
Scientists have unveiled a ground breaking way of treating influenza using innovative skin patches.

The breakthrough has the potential to spell the end of using needles to vaccine against pandemics.

It’s believed that the patches could be sent out in the post and could be administered by anyone with no need for medical training.

The skin patches possess several microscopic needles that are made of biodegradable plastic.

The needles can painlessly enter the surface of the skin and deliver the vaccination into the system.

Tests have so far indicated that the patch can possibly work better than the traditional way of vaccination using syringes.

Experiments have been conducted in laboratory’s on mice and revealed that the patches are better than injections at preventing flu.

This is due to the vaccine entering the body at skin level which is the most important area for the immune system.

In contrast syringes place the vaccine into muscles that are not as adept at producing immune reactions.

Those mice who received a second vaccination, three months after the first vaccination, through skin patches shrugged off influenza easier than the mice who received injections.

Professor Mark Prausnitz of the Georgia Institute of Technology in Atlanta gatech.edu who led the research team is confident that the breakthrough has the potential to transform vaccination.

He told the independent.co.uk “The dissolving micro needle patch could open many new doors to immunisation programmes by eliminating the need for trained personnel to carry out the vaccination.

“This approach could make a significant impact because it could enable self-administration as well as simplifying vaccination programmes."

Developing World may Benefit From Breakthrough

One of the greatest advantages from the skin patches could be the increased capacity for treating developing world patients.

The reductions in necessary infrastructure has the potential to expand immunisation programmes reaching more of those in need.

Currently inoculating with needles is expensive and needs trained professionals to carry out the injections.

There would also be less of a risk of contamination from dirty needles using the patches, and the problem of how to store needles that need to be reused would also be eradicated.

Skin Patch Vaccination: How it Works

Each skin patch is to be armed with 100 micro needles, made from the plastic polymer polyvinylpyrrolidone, and are already in use for medical equipment that is placed inside the body.

The micro needles, which are six times the thickness of human hair, are then covered with freeze dried vaccine.
After the micro needles have pierced into the skin they dissolve within a few minutes ferrying the vaccine into the most important cells in the immune system, which are prevalent in the skin.

The immune cells inside the skin are designed to capture the ‘antigens’ that are a component of the vaccines.
Further trials involving animals will need to take place and it could be several years scientists believe before the skin patches become used routinely.

Safeguard the Achilles

One of the most painful tendon injuries is Achilles. But there are also ways to avoid these injuries. Here are some of them: You’ll feel a burning and piercing in the tendon above your heel and it can even make a crackling sound when you move it. Any higher up your calf and it’s more likely that you’ve strained or pulled a muscle. Rupturing your Achilles tendon is a exceptionally painful experience and you’ll know when you’ve done it. Your Achilles tendon connects your calf muscles to your heel bone and is made of thousands of individual fibers of collagen. Restricted blood flow to this area slows repair and pain will worsen if you keep training . Four important factors in healing the Achilles are: rest, ice, compression and elevation. If your tendon is harmed take a break from all weight bearing sport (except swimming) for at least 2 weeks. You can recover from mild injury in a couple of weeks but a severe one can take 5 months. In order to prevent Achilles injury in

Stye - Symptoms and Treatment

A stye is an infection, typically a bacterial infection, which causes a painful red lump either on the edge or inside of the eyelid. Bacteria grow at the root of an eyelash follicle or inside an oil gland. The bacteria can be a result of poor hygiene, touching the eyes with unwashed hands or chronic inflammation. The stye resembles a pimple or a boil and is usually filled with pus. A stye does not pose a risk to vision and most often heals without treatment within a week. However, a stye may require treatment with a doctor if the infection does not resolve with at-home remedies. Symptoms of a Stye A stye is not usually hard to spot. Not only does a red lump form on either the top or bottom eyelid, but pain is also an immediate symptom of the condition. Typical symptoms of a stye include: red lump on the eyelid similar to a pimple watering of the eye eyelid pain and swelling clear or yellow fluid collecting in the stye A normal stye will come to a head in approximately three to

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi
