From adenoviruses to RNA: the pros and cons of different COVID vaccine technologies


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. […]

Here’s Why Viral Vector Vaccines Don’t Alter DNA


— 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 […]

What Do We Really Know About Adenovirus Vectors for Vaccines?


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 […]

Pros and Cons of Adenovirus-Based SARS-CoV-2 Vaccines


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 […]

What are Adenovirus-Based Vaccines?


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 […]

Adenovirus-vectored Vaccines for COVID-19 – How Do They Work?


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 […]

8 tools that helped us tackle the coronavirus


Authors: Ryan Cross , Laura Howes , Megha Satyanarayana ADENOVIRAL VECTORS Viruses might be nature’s most efficient gene-delivery vehicles. At its essence, a virus is simply a package that shuttles genes into a host cell, which it then hijacks to make more viruses. About 4 decades ago, scientists started hijacking the viruses themselves in an attempt to make novel vaccines. The […]
