Important Innovations

  3D Printed Alternative to Needles                                                                 Source:  UNC-Chapel Hill New Tech That's a Breakthru for Vaccines Researchers at Stanford University and the University of North Carolina-Chapel Hill have developed a 3D printed plastic patch as an alternative to COVID-19 vaccinations by needles.  The patch contains an array of microneedles that directly deliver the vaccine into the skin.  The researchers say the microneedle patch is ten times more effective in producing an immune response than a needle and it is painless. Microneedle patches have been under development for decades.  But the breakthrough on this revolutionary new patch came from 3D printing the microneedles on a polymer patch just long enough to reach the skin ...

Closing in on COVID Vaccines Source:  COVID Vaccine R&D EU Historic Stimulus Package Researchers at Oxford University in the UK, along with AstraZeneca, have developed a COVID vaccine that is proving to be successful at building immunity against COVID.  Human trials on more than 1000 patients have proven the vaccine effective.  The vaccine has moved into combined Phase 2 and Phase 3 trials - the last stop to prove it works.  AstraZeneca has a $1.2 billion deal with the US to deliver 300 million doses this fall, if the vaccine is approved. Two More Vaccines Meanwhile, at Moderna Pharma in Cambridge, MA, an experimental mRNA vaccine is in human trials and it is proving to be effective. It has produced antibodies in all the patients involved in the trials And, in China biotech Cansino's vaccine is showing positive antibody responses in a Phase 2 trial.  It is entering Phase 3 trials despite the fact it is not as effective on people over 55 years...

Universal, Cheaper, Stable Vaccines Source:  University of Texas Medical Branch Galveston DNA Vaccines that Could Impact World Health Scientists at the University of Texas Medical Branch in Galveston have developed a universal vaccine platform.  It cuts production and storage costs by 80%.  It can be stockpiled at room temperature for years.  And the new vaccines are as effective and safe as current vaccines. DNA Based Immunizations The breakthrough is that the scientists engineered the vaccines in DNA form.   According to the scientists, testing proved a resounding success with the desired immunizations resulting. Global Health Impact The scientists' findings and their new vaccine methodology was published in EBioMedicine.  This is of particular importance to hot, 3rd world countries where 80% of the vaccine cost comes from refrigeration.
