Where can I read about effectiveness of vaccines? I've got two Pfizer vaccine shots. Your post made me disappointed. All the time I thought that I'm more protected than others, but now it turns that my chances to die are simply much lower. I still can catch something and it might damage my organs...
I'm about to have my first abroad vacation during pandemic period. The vacation is already half spoiled, because most of places I can not simply visit even with vaccine certificate. In addition, I can be reverted back home after landing, because of silly rule "your kid got covid confirmed", while he is much younger than 12 years (in our country only people who are older than 12 years old can be vaccinated).

The article was published two weeks ago, based on a study done by Mayo Clinic Health System. The sample size was huge (>50,000) so I am sure that the numbers they are providing are closer to the truth. And the worst part is that Moderna is proving to be much more effective when compared to Pfizer. The former is 76% effective against the delta strain, while the latter has only 42% efficacy. Also, a study in Israel claims that the efficacy of mRNA vaccines get reduced after 6-7 months of the second dose.
This is interesting especially since Pfizer just got full FDA approval in the United States, which means that it is likely to increase market share as Moderna has not been fully approved and continues just to be approved on an emergency basis. If there really is such a large disparity it outcomes over time, hopefully Moderna will be approved and gain marketshare.
