This Symposium volume is based on selected presentations from the meeting and contains both reviews and research articles. It is divided into six topic areas that include genomics and pathogenesis. Of course CNN thinks that this is a horrible development, but in their article they also admit that this is working. SMi is proud to present the Transdermal and Microneedle Drug Delivery Conference, taking place on the 24th to 25th January 2022, in London. A section of a dissolving microneedle patch encapsulating a model vaccine (colored red). The key novelty of their new manufacturing process is to micro-mold vaccines into the shape of the microneedle core, and insert all of the molded vaccine cores into arrays of the microneedle shells at the same time, offering a fabrication method similar to the manufacturing process of computer chips, as shown in this video: “This is a tremendous advantage, compared to the previously-reported SEAL and other traditional methods to fabricate vaccine carriers, in which vaccine is often filled slowly one by one into each polymeric shell/carrier,” Tran says. Such patches resemble a piece of Velcro, with hundreds of tiny microneedles made of sugar. Yet vaccine trials are not to be hurried, as they ensure safety and efficacy.

Microneedle patch delivers COVID-19 DNA vaccine, doesn't require cold storage. Previous efforts to create such a single-injection vaccine include a technology called SEAL (StampEd Assembly of Polymer Layer), developed in 2017 by Nguyen, to create single-injection vaccine microparticles which can deliver vaccines after several defined periods, simulating multiple bolus injections. This is in major contrast to the vaccine, which creates immunity to just the spike protein of the virus, thus limiting the immunity and making it much easier for the virus to break through the vaccine-induced immunity.
