CDC SAYS NEW MEASLES VACCINATION COULD INCREASE GLOBAL COVERAGE

FROM:  CENTERS FOR DISEASE CONTROL AND PREVENTION
Microneedle Patch for Measles Vaccination Could Be a Game Changer
Promises to Increase Reach of Immunization Coverage Globally

A new microneedle patch being developed by the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) could make it easier to vaccinate people against measles and other vaccine-preventable diseases.

The microneedle patch is designed to be administered by minimally trained workers and to simplify storage, distribution, and disposal compared with conventional vaccines.
                                                                                                                                             
The microneedle patch under development measures about a square centimeter and is administered with the press of a thumb. The underside of the patch is lined with 100 solid, conical microneedles made of polymer, sugar, and vaccine that are a fraction of a millimeter long. When the patch is applied, the microneedles press into the upper layers of the skin; they dissolve within a few minutes, releasing the vaccine. The patch can then be discarded.
                                   
“Each day, 400 children are killed by measles complications worldwide. With no needles, syringes, sterile water or sharps disposals needed, the microneedle patch offers great hope of a new tool to reach the world’s children faster, even in the most remote areas,” said James Goodson, Ph.D., epidemiologist from the CDC’s Global Immunization Division. “This advancement would be a major boost in our efforts to eliminate this disease, with more vaccines administered and more lives saved at less cost.

Getting the measles vaccine to remote areas is expected to be easier because the patch is more stable at varying temperatures than the currently available vaccines and takes up less space than the standard vaccine. Because microneedles dissolve in the skin, there is no disposal of needles, reducing the risk of accidental needlesticks. The measles patch is expected be manufactured at a cost comparable to the currently available needle and syringe vaccine.

Twenty million people are affected by measles each year. Unfortunately, global coverage with the measles vaccine has been stagnant for the last few years at around 85 percent, which is well below the coverage of up to 95 percent needed to interrupt transmission of the disease.

Because measles is vaccine-preventable and the measles virus survives only in human hosts, the world’s health officials are aiming for measles elimination. Having a simple patch administered by minimally trained vaccinators could help increase vaccination coverage and achieve the goal of measles elimination.

MEASLES STILL A THREAT 50 YEARS AFTER MEASLES VACCINE APPROVED

FROM:  U.S. CENTERS FOR DISEASE CONTROL AND PREVENTION 
Press Release Measles Still Threatens Health Security
On 50th Anniversary of Measles Vaccine, Spike in Imported Measles Cases

Fifty years after the approval of an extremely effective vaccine against measles, one of the world’s most contagious diseases, the virus still poses a threat to domestic and global health security.

On an average day, 430 children – 18 every hour – die of measles worldwide. In 2011, there were an estimated 158,000 measles deaths.

In an article published on December 5 by JAMA Pediatrics, CDC’s Mark J. Papania, M.D., M.P.H., and colleagues report that United States measles elimination, announced in 2000, has been sustained through 2011. Elimination is defined as absence of continuous disease transmission for greater than 12 months. Dr. Papania and colleagues warn, however, that international importation continues, and that American doctors should suspect measles in children with high fever and rash, “especially when associated with international travel or international visitors,” and should report suspected cases to the local health department. Before the U.S. vaccination program started in 1963, measles was a year-round threat in this country. Nearly every child became infected; each year 450 to 500 people died each year, 48,000 were hospitalized, 7,000 had seizures, and about 1,000 suffered permanent brain damage or deafness.

People infected abroad continue to spark outbreaks among pockets of unvaccinated people, including infants and young children. It is still a serious illness: 1 in 5 children with measles is hospitalized. Usually there are about 60 cases per year, but 2013 saw a spike in American communities – some 175 cases and counting – virtually all linked to people who brought the infection home after foreign travel.
