![]() The reason that vaccines may be approved so quickly is that the large clinical trials to assess vaccine efficacy and safety are happening at the same time as the large-scale manufacturing preparation, funded by the federal government’s Operation Warp Speed program.” 4. ![]() “In my opinion, safety is not compromised by the speed of vaccine development and emergency use authorization. A lot of people have expressed safety concerns based on how fast these vaccines were developed, approved and distributed.Īccording to Petri, the vaccines still went through every normal step – they just did them simultaneously. ![]() “Safety is the first and foremost goal for a vaccine,” says William Petri, a Professor of Medicine at the University of Virginia. CDC/Alissa Eckert, MSMI Dan Higgins, MAMS 3. Just as the pandemic hit, mRNA vaccine research had reached a tipping point. “The hopes that gene-based vaccines could one day provide a vaccine for malaria or HIV, cure cancer, replace less effective traditional vaccines or be ready to stop the next pandemic before it gets started are no longer far-fetched,” explains Fuller. The Moderna and Pfizer vaccines are proof that mRNA vaccines are ready for prime time – and far surpass their predecessors. “DNA and mRNA vaccines offer huge advantages over traditional types of vaccines, since they use only genetic code from a pathogen – rather than the entire virus or bacteria,” writes Deborah Fuller, a microbiologist at the University of Washington who has been working on gene-based vaccines for decades. How do they work? Are they safe? Do I really need two shots? Why do they need to be kept so cold? And will this be the vaccine technology of the future? Below, we highlight five articles from The Conversation that will help answer your questions about mRNA vaccines. MRNA vaccines are proving to be more effective than anyone had hoped, but as with any new medical advancement, people have a lot of questions. These gene-based vaccines have been in the works for decades, but this is the first time they have been used widely in people. So far, the majority of doses have been either the Moderna or Pfizer vaccine, both of which use mRNA to generate an immune response. Tens of millions of people across the U.S.
