Effectiveness of the Bivalent mRNA Vaccine in Preventing Severe COVID-19 Outcomes: An Observational Cohort Study
SSRN (The Lancet) ^ | Ronen Arbel, Abel Peretz, et al.

Posted on 01/09/2023 6:56:56 PM PST by semimojo

Background: During Late 2022, the SARS-CoV-2 Omicron BA.5 sublineages accounted for most of the sequenced viral genomes worldwide. Bivalent mRNA vaccines contain an ancestral SARS-CoV-2 strain component plus an updated component of the Omicron BA.4/BA.5. Since September 2022, a single bivalent booster dose has been recommended for adults who have completed a primary vaccination series and are at high risk for severe Covid-19 disease. Evidence regarding the effectiveness of the bivalent vaccine in reducing hospitalizations and death due to Covid-19 is warranted.

Methods: This retrospective cohort study included all members of Clalit Health Services, aged ≥65, eligible for a bivalent booster. Hospitalizations and death due to Covid-19 among participants who received the bivalent vaccine were compared with those who did not. A Cox proportional-hazards regression model with time-dependent covariates was used to estimate the association between the bivalent vaccine and Covid-19 outcomes while adjusting for demographic factors and coexisting illnesses.

Findings: A total of 622,701 participants met the eligibility criteria. Of those, 85,314 (14%) received a bivalent-booster during the 70-day study period. Hospitalization due to Covid-19 occurred in 6 bivalent recipients and 297 participants who did not, adjusted hazard ratio (HR): 0.19 (95% CI, 0.08-0.43). Death due to Covid-19 occurred in 1 bivalent recipient and 73 participants who did not, adjusted HR 0.14: (95% CI, 0.02-1.04).

Interpretation: Participants who received the bivalent vaccine had lower hospitalization and mortality rates due to Covid-19 than non-recipients up to 70 days after vaccination.

Sure they worked. And all of the studies that show the opposite is happening with every “booster?”

Branch COVIDians. SPIT.

So where do you hang your naked picture of Fauci? Good lord, I cannot believe that you are trying to sell the same lies a second time.

Could you share one of these studies with us?

15K per day is not official. It is a guess by the BBC.

The US accumulated its death total so far with a significant portion 2020 pre-vax using weaker-than-China mitigation measures. China ruthlessly locked down pre-vax and added to their very strict Covid death criteria, reported few.

China’s present Covid death surge is post vax. So the comparison to US numbers, many of them pre-vax, cannot be pure. The triggering event in China is clearly the relaxing of mitigation measures, though we do know the US vax effectiveness fades, as does Sinovac. This confuses the results further.

Overall, these effects make comparisons doubtful.

No thoughts on what’s going on with medical coding...?

Think about it.

If you’re in the hospital with complications from influenza, but you’re coded as a CoupFlu patient, how are you counted by Big Med and Deep State?

And that’s just one of the issues.

We know how the same dire issues with medical data that we do with elections.

The people who compile/count it.
