Vaccines for COVID-19 moving closer

As the world reels from illnesses and deaths due to COVID-19, the race is on for a safe, effective, long-lasting vaccine to help the body block the novel coronavirus SARS-CoV-2. The three vaccine approaches discussed here are among the first to be tested clinically in the United States. How vaccines induce immunity: The starting line In 1796, in a pastoral corner of England, and during a far more feudal and ethically less enlightened time, Edward Jenner, an English country surgeon, inoculated James Phipps, his gardener’s eight-year-old son, with cowpox pustules obtained from the arm of a milkmaid. It was widely believed at the time that once milkmaids became ill with cowpox, a relatively mild disease, they were no longer susceptible to smallpox. The young boy became quite ill, but recovered in about a week. Jenner then injected James with material from a smallpox pustule and observed that nothing untoward happened. A new scientific approach to disease prevention was born. A century later, it became clear that vaccination — a term Jenner coined from the Latin name for cowpox, Vaccinae variolae — worked because vaccines induce protective immune responses. We now know that vaccines can generate neutralizing antibodies by activating immune cells called B lymphocytes that secrete those molecules. Antibodies specifically recognize a shape on a virus or a toxin and bind to it, much like a key that tightly fits into a lock. They can then block the virus or toxin fro...

Analysis suggests too little attention is paid to gender disparities in medical trialsCoronavirus – latest updatesSee all our coronavirus coverageHistorically, medical research has often taken a one-size-fits-all approach, lumping women and men together despite growing evidence that the sexes differ in how they catch and fight disease.A stark example was the heart drug digoxin, which was widely marketed in the late 1990s on the basis of a trial that showed it to beeffective and safe. But over time a higher incidence of side-effects in women emerged. When the same dataset wasanalysed on the basis of sex, it showed dig...

Authors: Mishra VN, Kumari N, Pathak A, Chaturvedi RK, Gupta AK, Chaurasia RN Abstract An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Wuhan City, China, in December 2019. Since then, the outbreak has grown into a global pandemic, and neither a vaccine nor a treatment for the disease, termed coronavirus disease 2019 (COVID-19), is currently available. The slow translational progress in the field of research suggests that a large number of studies are urgently required. In this context, this review explores the impact of bacteriophages on SARS-CoV-2, especially conce...
