The study, which has yet to be peer reviewed, had mixed but informative results. While the antibodies in those who had received their first shot of the vaccine were unable to neutralize the deadly South African variant known as B.1.351, the same group's T-cells — a type of white blood cells that play a central role in the immune system — were effective against all known variants. The antibodies in the same group were, however, able to fend off the highly transmissible UK variant, otherwise known as B117, as well as the original strain, moderately well. While both antibodies and T-cells play important roles in our immune system, antibodies are only able to fight pathogens including the SARS-CoV-2 virus by [attaching themselves to the outside]() of the pathogens. T-cells can both sense and destroy pathogens from inside infected cells and have lately become the subject of an [increasing number of studies]() involving the coronavirus. "It may not necessarily protect you against infection, but it’s very likely that this first dose will make it much easier for your immune system to make a good response the next time around," William James, a professor of virology at the University of Oxford who co-authored the Pfizer study, told *The Guardian*. "We think this is why that second dose produces such a good strong antibody response, because the T cells are already there, ready to react," James explained. Second doses, also commonly known as booster shots, were able to greatly increase the generation of antibodies, suggesting that they may play a more important role in the fight against the coronavirus than previously thought. "In more than 90 percent of cases, the antibodies that people are generating after the second dose are up at the sort of level that neutralises the virus and which we would expect to protect them from infection," James told *The Guardian*. "We’re pretty confident that they’ll be protected from infection by the South African strain and the Kent strain, as well as the \[original\] strain of the virus." The news comes just days after the COVID-19 vaccine manufactured by the University of Oxford and pharmaceutical AstraZeneca was [found to be ineffective]() against the South African variant. South Africa [stopped its planned rollout]() of the vaccine on Sunday as a result. In other words, scientists are still working night and day to understand the new variants — and our weapons against them. ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
