Shоwn belоw is аn excerpt frоm аn аrticle written by Esther Landhuis in the May 2022 issue of Scientific American. The title of the article is “What Does ‘Protection’ against COVID Really Mean?” Read the excerpt, then answer the questions that follow. More than two years into the COVID-19 pandemic, scientists are still scratching their head over a basic question: Is there something they could measure to tell if people are protected? Researchers call such measures “correlates of protection”—indicators that a person is unlikely to get seriously ill if infected by a pathogen such as SARS-CoV-2, the virus that causes COVID-19. Data so far have focused heavily on a single parameter: antibodies. These specialized proteins, produced by white blood cells called B cells after people get infected or vaccinated, help defend against future disease by blocking viral entry into cells. That protection is short-lived. Antibody levels start dropping in a few months. Yet “we’re not seeing hospitalizations go up as fast as antibodies are going down,” says immunologist E. John Wherry of the University of Pennsylvania. “So what gives?” A key source of protection for the previously infected, he and other experts suggest, are memory T cells. These durable immune cells do not necessarily stave off infection but do keep mild symptoms from worsening. Given their persistence, T cell levels measured in large numbers of people after infection or vaccination could help determine a correlate of protection. In fact, on April 21, Wherry and dozens of other researchers, physicians and biotech representatives sent a letter to the U.S. Food and Drug Administration urging the agency to monitor the abundance of T cells—alongside antibody levels—to better assess immunity at the city, state or national level to  determine the effectiveness of new vaccines undergoing review by regulators. “The need for many doses is not practical at a population level. We need vaccines that give broader protection and last longer, and there’s important work ahead,” said Ofer Levy, one of the letter’s signees, in a recent Harvard Medical School press briefing. Unlike neutralizing antibodies, T cells recognize a broad set of targets on the virus. Whereas antibodies attach to small fragments of a single protein—the protruding “spikes” on the surface of SARS-CoV-2—T cells detect not only snippets of spike but a wide range of other viral proteins.   Here are two questions to think about after reading the excerpt above: Q1: Consider the part of the excerpt above highlighted in yellow. Based on what you know about how T-cells work, explain why T-cells might not prevent viruses from getting inside cells, but yet they can make it harder for the virus to spread once it’s inside a cell. Q2: Consider the part of the excerpt above highlighted in green. Based on what you know about how T-cells work, explain how/why T-cells, as a whole, can recognize more parts of the spike protein as compared to B-cells. Question: Which of the two questions above would you prefer to answer for this exam?
