> How is this even possible in such a short amount of time? I Mutations on organisms such as viruses depend on the raw amount of virus duplication which happens, not per se "time", if you have a large amount of hosts, and therefore high amounts of duplication that increases the duplication rate making it more likely that mutations will occur, therefore speeding up the mutation rate, and as it happens with large countries still not taking strong measures against covid there's ample amount of hosts which can incubate new mutations.... Also, ought be noted that mutation is entirely random, this is *not* "a consequence to vaccines existing", most mutations will be neutral, others negative to the virus itself, but few might have positive effects on its vitality, or incubation period or others
