2. The vaccine effectiveness (VE) vs Omicron symptomatic infection vs Omicron falls off 15+ weeks, as was seen with the Israeli data, here more so with Pfizer compared to Moderna
3. But protection (VE) vs Omicron hospitalization remains quite high (Moderna > 90% thru 9 weeks)
4. First read out for VE vs Omicron fatality, in age 50+
95% with booster (59% without)
5. Summary data for VE vs Omicron over time for each outcome strongly reinforces the booster/Dose 3 impact and the high level of protection maintained vs hospitalization out to 6 months👍

New CDC genomic data shows continued rise of the KP.3 variant that accounts for 1 of 3 Covid cases.
LB.1 is gaining, too, as JN.1 fades away
This variant growth advantage plot by @BenjMurrell (H/T @siamosolocani) shows why this is the case. Note KP.3 is the one at far left w/ almost 3-fold advantage to JN.1.
Reinforces why the decision to develop the KP.2 vaccine booster (instead of JN.1) was a good one
Spike mutation map to show the differences betweem KP.3 and JN.1 (and LB.1, KP.2)
The connection between #SARSCoV2 and neurodegeneration
@TheLancetNeuro
Quotes below: 1. SARS-CoV-2 infection should be considered as a risk factor for Alzheimer’s disease, even though the distinction between causation versus disease acceleration is not clear.thelancet.com/journals/laneu…
2. Inflammation in patients with COVID-19, and controlled experiments show prolonged neuro-inflammation after mild SARS-CoV-2 infection
in macaques.
3. A direct correlation has been reported
between prior SARS-CoV-2 infection and increased risk
of Alzheimer’s disease (figure).
4. So far, the estimated lifetime cumulative risk of dementia due to hospitalisation for any viral infection is 1·48 (95% CI 1·15–1·91).
Breaking down the risks and benefit for lecanemab, the amyloid beta-directed antibody vs Alzheimer's drug approved @US_FDA last year. It doesn't look good.

Sorry, @washingtonpost, but this is not "another Covid-19 uptick" as you put it in your Health Alert. You ignore the best metric for infections that we have at present—wastewater—focusing only on hospitalizations washingtonpost.com/health/2024/01…
3 New #LongCovid reports 1. Vaccination protection—1 dose 21%, 2 doses 59%, 3 doses 73% among ~590,000 people in Sweden (strong association) bmj.com/content/383/bm…
2. 3-year prospective follow up of a cohort of ~1350 participants, hospitalized in China
—Lung function restored back to baseline in most
—Higher risk of reinfection that people w/o Long Covid
—Half w/ persistent symptoms thelancet.com/journals/lanre…
