Disclaimer - I have no particular understanding of these things. --- End quote --- isn't that basically the evolve in evolution? --- End quote --- I would have called it Natural Selection. That is to say, nothing new is produced. Instead, certain properties of an existing organism enable it's survival and consequent domination of it's environment. |

Would it still work? Would it cause any harm? --- End quote --- The multiple vaccines are not likely to interact at all as they target different, even if only slightly antigens. The Pfizer and Moderna vaccines provide mRNA that once inside the cell produce a protein fragment that is a portion of the virus spike. Your cells use this mRNA to make copies of this protein which your immune systems then reacts to by creating antibodies and T-cells. Once your immune system has reacted, it retains the ability to respond more quickly in the future. The second vaccine helps to boost the level of response to the presence of the COVID virus. As such, it is unlikely that one vaccine will help to boost the other since they create different antibodies for different antigens. |

Disclaimer - I have no particular understanding of these things. --- End quote --- isn't that basically the evolve in evolution? --- End quote --- Evolution consists of two separate things, mutation and selection. There is no guiding force causing mutations. They happen randomly and constantly resulting in a genome population with variation. When these mutations result in poor performance in the environment those organisms reproduce less often and the frequency of the genes they carry are reduced. When the mutations result in better survivability in the environment the frequency of the gene increases. In a disease population that is not wide spread (no where near herd immunity numbers) there is no competition. Many strains of the disease can spread without influence on one another. There is no real competition. Once herd immunity levels are approached only a significant mutation that prevents existing antibodies from attacking the virus will be able to spread widely. That is why we need to continue to take all precautions to minimize the spread of the disease; so the disease can be brought to Australian levels where it can be tracked and traced out of existence. |

Note I said logical, not ethical. |
