how does the immune system fight off viruses it’s complicated but basically when a virus enters your body it hijacks your cells and starts replicating your immune system detects this and sends in the tea cells to identify the virus then the tea cells release chemicals that activate other parts of the immune system like natural killer cells which kill infected cells and also be cells which produce antibodies that neutralize the virus but viruses are sneaky immutate constantly which allows them to escape the immune system’s detection that’s why we get sick with different strains of flu every year the immune system has to start from scratch each time but there is hope a new vaccine technology called mRNA has shown to be very effective at training the immune system to recognize and destroy viruses even if they mutate so it’s possible we ll have better vaccines for diseases like flu and covid-19 in the future this is 1 minute
