I pray it don't mutate again.

There are probably dozens of strains but that's normal, the variations between strains are usually small and being immune from one means being immune from all (or at least most) strains. If there's a major mutation, then it can be a different story. There are numerous measles strains for example but you only need the vaccine for "Measles A" and then you should be immune to all strains.


On a more positive note; most novel (new in humans) viruses become LESS severe in terms of symptoms / risk of death as they mutate over time. Viruses don't actually "want" the host to die - they want to exist as quietly as possible to spread as far as possible and live as long as possible in their host,so they become less severe as they adapt to human physiology.

They CAN mutate into something "worse" but its actually quite rare.
