Effectiveness of the Pfizer-BioNTech and Oxford-AstraZeneca vaccines on covid-19 related symptoms, hospital admissions, and mortality in older adults in England: test negative case-control study
Effectiveness of the Pfizer-BioNTech and Oxford-AstraZeneca vaccines on covid-19 related symptoms, hospital admissions, and mortality in older adults in England: test negative case-control study
Objective To estimate the real world effectiveness of the Pfizer-BioNTech BNT162b2 and Oxford-AstraZeneca ChAdOx1-S vaccines against confirmed covid-19 symptoms (including the UK variant of concern B.1.1.7), admissions to hospital, and deaths. Design Test negative case-control study. Setting Community testing for covid-19 in England. Participants 156 930 adults aged 70 years and older who reported symptoms of covid-19 between 8 December 2020 and 19 February 2021 and were successfully linked to vaccination data in the National Immunisation Management System. Interventions Vaccination with BNT162b2 or ChAdOx1-S. Main outcome measures Primary outcomes were polymerase chain reaction confirmed symptomatic SARS-CoV-2 infections, admissions to hospital for covid-19, and deaths with covid-19. Results Participants aged 80 years and older vaccinated with BNT162b2 before 4 January 2021 had a higher odds of testing positive for covid-19 in the first nine days after vaccination (odds ratio up to 1.48, 95% confidence interval 1.23 to 1.77), indicating that those initially targeted had a higher underlying risk of infection. Vaccine effectiveness was therefore compared with the baseline post-vaccination period. Vaccine effects were noted 10 to 13 days after vaccination, reaching a vaccine effectiveness of 70% (95% confidence interval 59% to 78%), then plateauing. From 14 days after the second dose a vaccination effectiveness of 89% (85% to 93%) was found compared with the increased baseline risk. Participants aged 70 years and older vaccinated from 4 January (when ChAdOx1-S delivery commenced) had a similar underlying risk of covid-19 to unvaccinated individuals. With BNT162b2, vaccine effectiveness reached 61% (51% to 69%) from 28 to 34 days after vaccination, then plateaued. With ChAdOx1-S, effects were seen from 14 to 20 days after vaccination, reaching an effectiveness of 60% (41% to 73%) from 28 to 34 days, increasing to 73% (27% to 90%) from day 35 onwards. On top of the protection against symptomatic disease, a further 43% (33% to 52%) reduced risk of emergency hospital admission and 51% (37% to 62%) reduced risk of death was observed in those who had received one dose of BNT162b2. Participants who had received one dose of ChAdOx1-S had a further 37% (3% to 59%) reduced risk of emergency hospital admission. Follow-up was insufficient to assess the effect of ChAdOx1-S on mortality. Combined with the effect against symptomatic disease, a single dose of either vaccine was about 80% effective at preventing admission to hospital with covid-19 and a single dose of BNT162b2 was 85% effective at preventing death with covid-19. Conclusion Vaccination with either one dose of BNT162b2 or ChAdOx1-S was associated with a significant reduction in symptomatic covid-19 in older adults, and with further protection against severe disease. Both vaccines showed similar effects. Protection was maintained for the duration of follow-up (6 weeks). A second dose of BNT162b2 was associated with further protection against symptomatic disease. A clear effect of the vaccines against the B.1.1.7 variant was found.

The Red/Blue Divide in COVID-19 Vaccination Rates Continues: An Update | KFF
This analysis is an update to a previous analysis conducted in September 2021. Using county-level data, we analyzed trends in COVID-19 vaccination rates in counties that voted for President Trump in the 2020 election compared to counties that voted for President Biden. We find higher vaccination rates for counties that voted for Biden. However, rates among those fully vaccinated that have received a booster are similar between the two groups.

Is the Covid 'lab-leak' theory incorrect? What new study reveals
A study by the University of Edinburgh suggests Covid-19 did not originate in China’s Wuhan but evolved naturally in the bat population in northern Laos and China’s Yunnan province. The study, now published in the peer-reviewed journal Cell, challenges the ’lab-leak’ theory championed by US President Donald Trump. Here’s what it says

It's Not News, Nor 'Scandalous,' That Pfizer Trial Didn't Test Transmission - FactCheck.org
The COVID-19 vaccine clinical trials were designed to study the vaccine’s safety and efficacy in preventing symptomatic disease, not transmission. But online publications now misleadingly present the fact that the Pfizer/BioNTech vaccine was not tested for transmission as a “shocking admission” and proof that the company and the government lied.

Yes, vaccines curb COVID-19 transmission — but that's not enough to protect those without a shot
Even as highly contagious coronavirus variants are circulating, experts say leading vaccines are not only preventing infections but likely curbing transmission as well. But that doesn't mean the vaccinated can fully protect the unvaccinated, particularly in areas with lower vaccination rates.
