How can Ayurveda help in boosting human immune system?

Every second another fellow human is being attacked by Covid-19. Everyday there is a fear that one of our loved ones or even us ourselves might get the covid-19. As long as humans know, we humans have always overcome any problem humanity as ever faced, keeping that in mind, I believe that we can overcome this one too. We should come together (I mean that figuratively not literally) and help kick away Covid-19 and the rest of it's family. And to do this, we need to boost our immunity and follow the scientific ways of Ayurveda.
