Authors: Joel Abrams The World Health Organisation lists about 180 COVID-19 vaccines being developed around the world. Each vaccine aims to use a slightly different approach to prepare your immune system to recognise and fight SARS-CoV-2, the virus that causes COVID-19. However, we can group these technologies into five main types. Some technology is tried and trusted. […]
— It’s pretty simple — they can’t Authors: by Veronica Hackethal, MD, MSc, Enterprise & Investigative Writer, MedPage Today March 12, 2021 Adenoviral vector vaccines have been in development for decades, but very few have been approved for use in humans. What does the history of adenoviral vector vaccine development tell us about their safety and their […]
Authors: BY TYLER DURDEN As shares of MRNA-vaccine purveyors Moderna and BioNTech tumbled on Wednesday, Reuters reported that the EMA, the EU’s medicines regulator, is looking into new potential side effects from the still-experimental MRNA jabs, including suspicious skin reactions and kidney ailments. According to Reuters, three new conditions have been reported by a small number […]
Authors: Caitlin Owens A new preprint study that raises concerns about the mRNA vaccines’ effectiveness against Delta — particularly Pfizer’s — has already grabbed the attention of top Biden administration officials. What they’re saying: The study found the Pfizer vaccine was only 42% effective against infection in July, when the Delta variant was dominant. “If that’s not a wakeup call, […]
Authors: By Serena Marshall and Lara Salahi February 24, 2021 — The newest COVID shot uses an existing technology but one with lingering questions As the U.S. hits the half-million death mark from COVID-19 — a grim milestone that is equal to roughly the entire population of Atlanta and more than that of Miami — a new […]
Authors: Eric J. Kremer1,∗ Main Text Most of us might be surprised by the rudimentary scientific rationale prevalent in the field of vaccine research just 50 years ago. For over a century after Louis Pasteur’s vaccine against rabies, approaches usually consisted of inactivating a virus, injecting it, and seeing if it protected the host. Unlike […]
Authors: By Dr. Sanchari Sinha Dutta, Ph.D.Reviewed by Sophia Coveney, B.Sc. Adenoviruses are considered excellent vectors for delivering target antigens to mammalian hosts because of their capability to induce both innate and adaptive immune responses. Currently, adenovirus-based vaccines are used against a wide variety of pathogens, including Mycobacterium tuberculosis, human immunodeficiency virus (HIV), and Plasmodium falciparum. What are adenoviruses? Adenoviruses are […]
Authors: Heather D. Marshall, PhD | Vito Iacoviello, MD Viruses are genetic material surrounded by a protein shell with the ability to infect cells, highjack cellular machinery, and make copies of themselves. Viruses are also detected by the immune system and stimulate innate and adaptive immune responses and quite often, potent immunological memory that protects the host […]
