The flu vaccine is extremely ineffective, even the CDC admits it publicly. I've gotten the flu vaccine once in my life and that same season I got the second sickest I've ever been in my life with a fever between 102 and 104 degrees sustained for five consecutive days. In any case, why was mask wearing never encouraged in the past during flu seasons. If masks actually work, they could save tens of thousands of lives annually in the United States, and hundreds of thousands globally.
And what if a permanent solution doesn't come about?
Of course people don't want to wear masks indefinitely. My point is that there is a double standard. While COVID is worse than the flu, many people die from the flu every year, including those who were vaccinated. So it's inconsistent to advocate for masks in this scenario and not in the other. Either one should be in favor of mandatory masks at all times, or never. Any other position is inconsistent with reality.
