The number of people I see calling for Nazi-style restriction of movement, working, and even living based on vaccination status is utterly terrifying. The people who thought that a bakery should be forced to make a cake for a customer now support companies only hiring or serving vaccinated people (good for them! Happy!) while decrying companies who hire or serve only unvaccinated people (they're evil! Sad!) technically exercising the same freedom as evil.
The US is not the entirety of the world, vaccinated people still catch and spread the virus at the same rates even if they have no symptoms, not quite 50% of the entire world population has been vaccinated. The crowd of "if wearing a mask saves just one life" has turned into a group of fascist pieces of filth.
One. Freaking. Year.
This is the research that caught my attention: Findings from a UK study showing vaccines are helping
Reading your sources, I saw this:
Now if they were to combine the mRNA vaccine with an inactivated virus vaccine, would that allow the immune system to evolve and give better resistance to the variants as they occur?
Your sources actually reinforced my statement about the current vaccines reducing the severity for breakthrough cases.
