The BNT162b2 Pfizer/BioNTech COVID-19 vaccine retains its efficacy against B.1.1.7 in the UK and in reports from Israel.
“Current epidemiological evidence is that the BNT162b2 Pfizer/BioNTech COVID-19 vaccine retains its efficacy against B.1.1.7 in the UK24 and in reports from Israel.28,29”
From Impact of SARS-CoV-2 variants on the total CD4+ and CD8+ T cell reactivity in infected or vaccinated individuals (2021) · cites this paper as [28]
Vaccine coverage of 79%, 90%, and 65% was reported in three recent single-centre studies of health-care workers in Israel and the UK.
“three recent single-centre studies in health-care workers in Israel and the UK reported vaccine coverage of 79%, 90%, and 65%, respectively.”
Variability in vaccine effectiveness estimates between studies could result from differences in study design, testing protocols, and study populations.
“Variability in estimates of vaccine effectiveness between studies could result from differences in study design, testing protocols, and study populations”
Current vaccination efforts are resulting in substantial preventive benefits among working-age adults.
“These interim vaccine effectiveness findings for both Pfizer-BioNTech’s and Moderna’s mRNA vaccines in real-world conditions complement and expand upon the vaccine effectiveness estimates from other recent studies (3–5) and demonstrate that current vaccination efforts are resulting in substantial preventive benefits among working-age adults.”

“Amit et al estimated a vaccine effectiveness of 85% from 1528 days after the first dose, though they also estimated a 45% reduction from days 1-14 which may indicate that those vaccinated had a lower baseline risk.(31) It is not clear whether this analysis is based on symptom onset date or test date.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
