Covid-19 prevention research focuses on identifying and implementing measures to reduce the transmission of the SARS-CoV-2 virus, which causes Covid-19. This includes studying the efficacy of vaccines, testing strategies, mask-wearing, social distancing, and other public health interventions. Researchers are also investigating the role of factors such as age, underlying health conditions, and immune responses in determining susceptibility to the virus. The goal of this research is to develop evidence-based guidelines and strategies to prevent the spread of Covid-19 and protect public health.
