A cashier and her friend were discussing what vaccine is better in front of me. They agreed that AstraZeneca is the worst and they should avoid it. They were talking because their bosses want to vaccinate all the employees. I had a strong desire to tell them that all the covid vaccines are dangerous, but I didn't. I know by experience that average people will never believe a stranger saying something like this if mass media are silent. All I understood is that at least average people don't trust all covid vaccines.
