placeholder Posted June 21, 2021 Share Posted June 21, 2021 Apparently, these results were about being vaccinated just once with the Pfizer vaccine: "The study found that after just one dose of the Pfizer jab, people are less likely to develop antibody levels against the Indian (B.1.617.2) variant, also known as Delta, as high as those seen against the previously dominant Kent variant (B.1.1.7) also known as Alpha." Also, there's this: Two doses of vaccine highly effective against Delta variant, U.K. officials say Two doses of the Pfizer-BioNTech or the AstraZeneca Covid-19 vaccines are highly effective against hospitalization from the Delta variant of the coronavirus, according to a new analysis from Public Health England released Monday. The new analysis found that two doses of the Pfizer vaccine were 96 percent effective against hospitalization from the Delta variant, and two doses of the AstraZeneca vaccine were 92 percent effective. “We know from the phase one studies that the second shot induces a level of virus-specific neutralizing antibodies that’s about tenfold greater than that after the first dose.” https://www.nbcnews.com/health/health-news/two-doses-vaccine-highly-effective-against-delta-variant-u-k-n1270776 1 Link to comment Share on other sites More sharing options...

Why can't we just have one definition ? Link to comment Share on other sites More sharing options...

Jajazazajaja Posted June 21, 2021 Share Posted June 21, 2021 These articles make me so angry. They mislead people by only talking about 1 dose, it’s really sad to see people mislead like this Link to comment Share on other sites More sharing options...

AnnieSeek Posted June 21, 2021 Share Posted June 21, 2021 (edited) 1 hour ago, cdemundo said: Because it's complicated? not really. Let's just have one universal percentage for one universal terminology. When i read 'EFFICIENCY' i take it to mean symptomatic disease. When i read 'hospitalisations' well thats obvious. But sometimes they play around with these two. Edited June 21, 2021 by AnnieSeek Link to comment Share on other sites More sharing options...
GroveHillWanderer Posted June 21, 2021 Share Posted June 21, 2021 10 hours ago, AnnieSeek said: They are becoming quite word savy here - sometimes they quote you a percentage for symptomatic efficiency, then they change the rules and it becomes efficency against 'hospitalisations'. Why can't we just have one definition ? Efficacy is always measured against a specific clinical endpoint. Since there are different endpoints (e.g. symptomatic infection, hospitalisation, severe illness, death etc) then there are different levels of efficacy against each of those different outcomes. If they'll only gave the efficacy in relation to one of the possible endpoints, that wouldn't tell you how effective it is in relation to the others. For instance, wouldn't you want to know how effective a vaccine will be in preventing you from dying? If you only have the efficacy against symptomatic infection, you wouldn't know how good it is at actually keeping you alive. Link to comment Share on other sites More sharing options...

Why can't we just have one definition ? Because there is more than 1 concern to address. 2 to be precise. One is about how well vaccines prevent it from being transmitted to others and the second concern is how seriously it will affect people who have been vaccinated. Both are legitimate concerns, don't you think? Link to comment Share on other sites More sharing options...
