wtf are you talking about? trial data - "prevents 95% of cases" https://www.statnews.com/2020/11/18/pfizer-biontech-covid19-vaccine-fda-data/   early data from Israel - "Israeli study finds Pfizer vaccine 95% effective against COVID-19" https://www.reuters.com/article/us-health-coronavirus-israel-pfizer/israeli-study-finds-pfizer-vaccine-95-effective-against-covid-19-idUSKBN2AH281 early US data of 4k health workers - "'Real world’ study by CDC shows Pfizer and Moderna vaccines were 90% effective"  https://www.statnews.com/2021/03/29/real-world-study-by-cdc-shows-pfizer-and-moderna-vaccines-were-90-effective/"   Pfizer 88% effective against Delta in the UK - "Wednesday's study found that two doses of Pfizer's shot was 88% effective at preventing symptomatic disease from the Delta variant, compared to 93.7% against the Alpha variant"- https://www.reuters.com/business/healthcare-pharmaceuticals/two-doses-pfizer-astrazeneca-shots-effective-against-delta-variant-study-finds-2021-07-21/   Moderna and Pfizer 90-92% effective against Delta in Canada - https://www.alberta.ca/stats/covid-19-alberta-statistics.htm#vaccine-outcomes   There has literally been like one piece of data quoting an "ineffectiveness" against Delta, the Israel charts that were released (which even still said "39% effective" which is still better than zero).  But as I posted yesterday, that may have been based on incomplete data.
