#3: New Flu Vaccine Patch Proving as Effective as Standard Injection
Although some participants who received the patch reported mild skin reactions such as localized redness or itching, none of the participants reported serious adverse reactions. Participants who received the vaccine via patch or injection had similar antibody responses. More than 70% of those who received the patch preferred that delivery method over the flu shot. The participants who applied the patches to themselves received similar vaccine doses to those whose patches were administered by healthcare workers, showing that the delivery method could eliminate the need for a trip to the doctor’s office.
“This bandage-strip sized patch of painless and dissolvable needles can transform how we get vaccinated,” said NIBIB director Roderic I. Pettigrew, MD, PhD in the press release. “A particularly attractive feature is that this vaccination patch could be delivered in the mail and self-administered. In addition, this technology holds promise for delivering other vaccines in the future.”

#2: HIV Vaccine Moves One Step Closer to Becoming Reality
Scientists from The Scripps Research Institute and the La Jolla Institute for Allergy and Immunology may have found the best delivery mode for a vaccine against HIV. The results of their new study show that “optimizing the mode and timing of vaccine delivery is crucial to inducing a protective immune response in a practical model,” according to a press release on the study.
For their study, published in the journal, Immunity
, the scientists found that, “administering the vaccine candidate subcutaneously and increasing the time intervals between immunizations improved the efficacy of the experimental vaccine and reliably induced neutralizing antibodies.” These antibodies are key in promoting an effective immune response as they inactivate an invading virus before it is able to set up shop in the body. According to the press release, these neutralizing antibodies, “have been notoriously difficult to generate for HIV.”
