The effect of 3D printed vaccine patch is ten times stronger than traditional injection, and it can also complete the vaccination by itself

Science and Technology Daily, Beijing, September 27 (Reporter Liu Xia) According to a report by the Physicist Organization Network on the 26th, researchers at Stanford University and the University of North Carolina at Chapel Hill have created a 3D printed vaccine patch

Related research papers were published in the latest issue of the Proceedings of the National Academy of Sciences.

According to the researchers, the vaccine patch is convenient, easy to use and effective, and provides a new method for vaccination.

The results of the study showed that the vaccine patch produced a significant T cell and antigen-specific antibody response, and the immune response generated was 10 times stronger than subcutaneous injection

Microneedle patches have been studied for decades, but with little success

The new crown epidemic has made people aware of the importance of vaccination, but vaccination has to go to the hospital and requires professional injection; in addition, the vaccine also needs to be refrigerated

Researchers are continuing their efforts to make RNA vaccines (such as Pfizer and Modena's new crown vaccine) into microneedle patches for future testing

De Simon said: “One of the biggest lessons we learned during the new crown epidemic is that scientific and technological innovation can determine the success or failure of the global response.

When viewing short videos, one can often see babies who have received the newborn vaccine, wearing a "pain mask" at the moment of the injection, and crying
