However, this vaccine is non-sterilizing, meaning that it does not stop people from getting infected in the nose but stops progression to the lower respiratory tract thus preventing hospitalization. Before the delta variant the vaccines also worked surprisingly well at reducing infections, but with the Delta variant this is much less clear (if you have any links to studies on this topic I am very interested to see them).
Now we are risking the opposite situation. Most people that I encounter say "I am fully vaccinated" (so I don't need to wear a mask, take precaustions, etc). But the studies on these COVID vaccines have always shown that with great enough exposure the vaccinated will get infected and transmit that infection to others.
