Nobody at Tencent has liked to be vaccinated, especially children, but no matter how painful the vaccination is, it is always much better than being sick. Despite the potential risks of vaccines, the data show that in the United States alone, the vaccine has left millions of children away from the disease. Therefore, vaccination is absolutely necessary.
Then again, it is quite painful for children to inject vaccines. Fortunately, a recent concept study "MucoJet" from the University of California, Berkeley, was successful and is expected to replace injection equipment within ten years.
The R&D staff used a 3D printing device to print out MucoJet and experimented with animals. Experiments have shown that MucoJet can import vaccine-sized molecules into the immune system through the mouth, which plays the same role as the vaccine.
The use of MucoJet is similar to that of a vaccine. First you need to squeeze the MucoJet, then let the device stay on your cheek for about ten seconds. At this time. MucoJet's high-pressure fluid flow and immune system trigger molecules to penetrate the mucosal layer to stimulate the cheek's immune response. That is, the pressurized jet replaces the pain caused by the needle.
Kiana Aran, a professor of mechanical and bioengineering at the R&D team, said: Compared to traditional needles, MucoJet can more effectively enter the immune system and trigger an immune system response.
At the same time, Kiana Aran said: Most modern second-second methods using muscle or subcutaneous injections, because the vaccine itself contains live virus components, so the safety and effectiveness when passing through the mucosal surface is limited. MucoJet injections can be safer and more effective.
Until now, MucoJet's R&D team has successfully performed experiments on animals. In the future, MucoJet will also need to conduct experiments on larger animals such as monkeys and pigs. Research and development staff said: Ideally, MucoJet is expected to be listed in the next five to ten years.
