Next generation vaccine production

For decades, conventional inactivated vaccines have been produced by killing pathogens with toxic chemicals. However, this process often changes the surface structure of the pathogens to such an extent that the immune system is only able to induce a weak response. KyooBe Tech GmbH is offering a method that uses low-energy electrons to inactivate pathogens. Vaccines produced this way are much higher quality, making them safer and more effective.
