They're certainly less effective vs variants, but I haven't seen any convincing data suggesting that vaccines are totally ineffective against them. In fact, the article also quotes one of the authors as saying: "The bottom line is, this can happen — it can be true that vaccinated people can spread the virus. But we do not yet know what their relative role in overall community spread is."

Looks like against delta the vaccines could have as low as 39% efficacy against preventing symptomatic COVID. https://www.cnbc.com/2021/07/23/delta-variant-pfizer-covid-vaccine-39percent-effective-in-israel-prevents-severe-illness.html https://www.cnbc.com/2021/07/23/delta-variant-pfizer-covid-v...

  We keep using percentages as if they had a true meaning. All the values that keep flying around cannot be compared, as they all measure slightly different things. That 39% number (protection against symptoms) wasn't checked at the trials, or at least wasn't reported. In that same article, they state that protection against being hospitalized/ICUed is still around 90%, which are the same values we heard before. Guess that doesn't sell clicks.

    It absolutely was reported and tested for, please don’t spread misinformation.

      If that is the case, it has absolutely nothing to do with the reported "around 90% effectivity" that was in the headlines for the four main vaccines. Saying that delta diminishes the effectivity from over 90% to 39% is spreading misinformation. Implying it, as the above linked article does, is spreading misinformation, knowing that lots of people doesn't read beyond the headline. Vaccines are still more than 90% effective against delta variant, or any other variant so far. The 39% above only means that vaccinated people has "only" that protection against being infected (that is, being positive on a PCR test). Even if you are asymtomatic you are counted as infected, thus the vaccine alegedly didn't protect you. But vaccinated people still has around 90% protection against being hospitalized, even in delta variant environments. The only conclusion we can get is: herd immunity is still far. Get vaxxed ASAP, because this thing will keep spreading.

        Even if you are asymtomatic you are counted as infected Incorrect the vaccine trials only tested for symptomatic COVID not asymptomatic, so your assertion here is wrong. The 39% number is for symptomatic COVID only. Also if you read my original comment you’ll see I only refer to symptomatic COVID and not to death or hospitalizations, perhaps you should read more closely before blindly accusing me of being misleading.
