Vaccines are one of the greatest health interventions ever developed. They’ve been cited as being as important to keeping communities healthy as having access to clean water and safe sanitation.1 Through scientific investment and ingenuity, today we
First: mRNA vaccines are quicker to develop than traditional vaccines—which take years. With mRNA vaccines, once researchers have genetically sequenced the virus and have identified an immunogen, a vaccine can be ready for clinical trials in as little as a few weeks. This is how the Pfizer/...
People around the world are now getting jabs of the new coronavirus vaccines. Two of them, one made by Pfizer and BioNTech and another made by Moderna are unlike any other vaccine. Instead of using weakened or inactivated components of the virus to activate the body’s immune response, thes...
The flu vaccine. The COVID-19 vaccines. You may have a lot of questions about them – and if they work together. Read on to learn what makes each vaccine different and why it’s important to get both vaccines this fall. Flu vaccines and COVID-19 vaccines: What’s the difference? Whi...
Both use a technology called messenger RNA (mRNA), which has been studied and experimented with for decades in different forms, but has never been used in a commercial vaccine. Pfizer and Moderna, the companies behind the two most promising mRNA vaccines, are building on years of resear...
Since none of the explored therapies can directly kill the virus, vaccines have become the last hope to stop the pandemic. However, vaccine development is generally a time-consuming process, taking years to complete. As a great surprise, Moderna Biotechnology, Inc. delivered a vaccine named mRNA...
“The protein is put on the cell, the immune system recognizes it and makes antibodies — therefore immunity.” The mRNA vaccines are similar, but structurally different with Brown simplifying it by saying Pfizer and Moderna “put the RNA right into your arm.” ...
scientists aren't sure about this yet -- it could be problematic for other vaccines using adenoviruses, such as the Johnson & Johnson's and Russia's Sputnik V. (TheModerna and Pfizer vaccines use mRNA, a different technology.) Researchers have begun to see some extremely rare cl...
have been linked with an increased risk of the disease. This has also beencovered in a blog on Covid-19 mRNA vaccinesthat Chris Woollams put together on the finding in approximately six studies of extraneous DNA fragments, including SV-40, in the Pfizer and Moderna Covid-19 vaccines. Not...
opportunities for creating future mRNA vaccines that are tailored to fight different infectious diseases. Other scientific advances over the last two decades, such as encapsulating the mRNA into fat molecules known as lipid nanoparticles (LNPs) to protect the molecule and enhance its delivery into ...
