Hursty AZ proven to be useless against current strains, absolute shambles
How did you come to that conclusion?
There was one study posted above with a tiny sample size, which claimed 2xAZ was ineffective at preventing “symptomatic infection”.
However, “symptomatic infection” means the sniffles. 2xAZ still appears to be very effective against serious illness.
Another example of fear-mongering and paranoia caused by social media and press spin, combined with people being incapable of reading properly.
