Still something like 93% effective against severe illness, yes? I think that's what I saw. Still among the best vaccines ever developed. Once they get their BLA later this summer, I *think* they'll be able to put out modified shots as an addendum to the BLA the same way flu vaccines do every year. The benefit there is they can likely get them into your local Walgreens or CVS in a matter of weeks upon emergence of a new variant that's evading the existing vaccine. J&J will be left in the dust at that point.
“Reports from Israel that Pfizer may only be about 64% effective against mild cases of Delta variant, but still strong against severe disease”
“Still something like 93% effective against severe illness, yes?”
I think that is what was just reported in Israel.
On another post, someone posted a paper from “Public Health England” (Technical briefing 17
25 June 2021), https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/997418/Variants_of_Concern_VOC_Technical_Briefing_17.pdf
On page 39, they indicate that the vaccine (I believe they are talking about Pfizer BioNTech, but did not verify), was less effective against Delta for symptomatic Disease (79%, vs 89% against Alpha, for fully vaccinated), but was actually MORE effective against hospitalization from Delta (96%, vs. 93% against Alpha, fully vaccinated).
On a different topic, it also notes that C.37 (Lambda), the Peruvian variant, is now on their radar screen as a Variant Under Investigation.
