It wasn’t vaccine development that was “rushed”. The general principle of mRNA vaccines and the mechanism of action has been clearly understood for many years. It’s the regulatory process that was rushed (rightfully so) which expedited delivery of the vaccine.
when large groups of people (esp those immunocompromised) are not vaccinated, the viral load can increase in their bodies allowing the virus to mutate. That’s why you see delta omricon etc. this will go on until we reach herd immunity. Think of the vaccine like a ring placed around a house in a neighborhood during a fire. Eventually if enough houses have a ring around them, the fire has no where to spread and naturally dies off. Now here lies the rub, unless people in other countries have the same rates and access to vaccines as we do in the United States, it all doesn’t matter since they can have the virus mutate over there as well…unless we isolate ourselves.
