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...

Background Cardiovascular disease is a significant health problem in the United States, attributed to more than 30% of all deaths annually. Anxiety has been associated with cardiovascular disease risk and is thought to be associated with cardiovascular disease risk through inflammatory pathways. Objective The purposes of this study were to examine the relationship between anxiety and systemic inflammation in individuals at risk for cardiovascular disease and to determine if single-nucleotide polymorphisms (SNPs) associated with inflammation moderate this relationship. Methods A secondary analysis was cond...

Conclusions Young adults are not armed with the accurate knowledge to make informed choices about using e-cigarettes. E-cigarette users are understudied and tend to value appearance and physical sensation over health. Social norms related to e-cigarette use are linked to perception of identity and the current technology-focused culture.
