"It decreases the possibility that a vaccine-resistant strain is running around. We're not just trying to prevent the spread, but the evolution of novel variants, which are so rare at this point that we haven't yet identified them," he said. The model also simulated waves of low and high transmission, similar to the effects of large-scale interventions such as lockdowns.The study showed that three factors increase the probability of a vaccine-resistant strain taking hold:These factors, Rello said, are obvious to some degree.
