Yes exactly. There could still be some nasty surprises in store with more dangerous variants (higher death rate, affects children etc - I really hope not). We will know soon. There are now populations that Delta has ravaged with and without vaccines so we should be able to do comparative studies and tell the difference soon with regards to immunity response between the two against new variants should one start spreading. The 2 year thing - the world is different than in 1918 and the virus is different so it might not go exactly the same way. But I’m hoping natural immunity and infection together will stamp it out soon. Would suck if the people who were vaccinated first will never be able to form broad long lasting immunity, or if vaccination has the effect of creating selective pressures of changing just the spike protein in some nasty way, which wouldn’t have necessarily happened if we had natural broader immunity. I am also vaccinated for the record, and amazed at the technical feat and future potential of mRNA vaccines. But evolution and immune systems are complex things.
