NanoPass Intradermal Injection Platform Proven to Support COVID-19 Vaccine Antibodies Using 1/15 of the Dose Reports China Institute of Medical Biology

NES ZIONA, Israel and Shanghai, China, February 7, 2022 /PRNewswire/ — Intradermal COVID vaccination studies are emerging as part of a global effort to increase available doses by harnessing skin immunity to reduce the dose required for effective vaccination. In a landmark study published recently by scientists at IMB[1], subjects were immunized twice with IMB’s inactivated SARS-CoV-2 vaccine intramuscularly. Approximately six months later, 20 participants randomly received 1/15 (™600 device. Significant increases in antibody levels were demonstrated one week and 2 months after injection (X8-10 and X12.5-97 from baseline, respectively). Six months later, antibody levels were reduced but remained significantly higher than baseline (X8.5-12). These results showed that the 3rd intradermal boost provided robust and sustained immunogenicity (>6 months) with favorable safety (no fever and only mild redness and swelling at the injection site).


CEO of NanoPass, Dr. Yotam Levin said: “We commend Chinese researchers for their continued pioneering work during COVID-19, with the goal of developing, evaluating and improving vaccines against this horrific pandemic. Excitingly, the study design n used only 1/15 of the dose, potentially allowing a 15-fold increase in available doses and demonstrated durability of response for at least six months. The study was conducted with the MicronJet600 injection device, which is registered in China and most major markets, and which provides consistent intradermal inoculation.”


This step is a joint effort between NanoPass and YNC, who supported IMB. YNC has been working hard to promote NanoPass intradermal delivery platform in China and this cooperation is a major step on the way to helping China fight against COVID-19.


CEO of YNCNi Jian says: China has made significant progress in the fight against COVID, however, antibodies drop to a significantly low level six months after vaccination, providing a hotbed for the recurrence of the pandemic. This means that finding a way to improve antibody levels and maintain such high levels for longer becomes critical. Thanks to the reliability and consistency of MicronJet600 for intradermal injections, IMB, with our support, found a method to significantly increase the antibody level (from 8 to 97 times) and maintain it at a high level for at least six months. This milestone discovery and follow-up study should provide important weapons for global victory over COVID-19.
