@David Somewhere along the line--maybe a scant 7 days after the message--the warning that vaccine only took full effect 14 days after, was lost. Also, people took antivirals. These were never a cure, were they?
Can anyone state...categorically...how many infections will cause Long Covid, when there are Long Haulers from #Alpha, and #Delta, and #Omicron, after a single *known* infection?
Abandoning the science wasn't such a good idea.

Effect of Severe Acute Respiratory Syndrome Coronavirus 2 (#SARSCoV2) Reinfection on Long-Term Symptoms in the Innovative Support for Patients With SARS-CoV-2 Infections Registry (INSPIRE)

> The timing of initial infection, reinfection, and the variants involved may play important roles in longer-term clinical outcomes. Repeated infection with Omicron variants may increase the risk of long-term symptoms.

> For individuals who experienced their first infections in either the pre-Delta or #Delta periods, the odds of having ≥3 symptoms 3–6 months after their most recent infection was lower in those reinfected than those with a single infection (weighted adjusted odds ratio, 0.45 [95% confidence interval, .21–.95] and 0.51 [.32–.79], respectively). However, in individuals reporting their first infection during the #Omicron wave, the odds of reporting ≥3 symptoms after the most recent infection was higher in those reinfected than in those with a single infection (weighted adjusted odds ratio, 1.54 [95% confidence interval, 1.02–2.34]).

pmc.ncbi.nlm.nih.gov/articles/ “The overall SAR of 37.2% was lower in the contacts of both vaccinated index cases (34.9% vs. 63.2%; p = 0.014) and index cases with a previous SARS-CoV-2 infection history (27.0% vs. 46.3%; p = 0.002). Index case vaccination showed a protective effect against infection for their household contacts (aOR = 0.21; 95%). The household SAR was high when the #Omicron variant circulated. Vaccinated index cases were less likely to transmit #SARSCoV2 to their contacts.”

PubMed Central (PMC)Vaccinated COVID-19 Index Cases Are Less Likely to Transmit SARS-CoV-2 to Their Household Contacts: A Cohort StudyThe aim of this study was to evaluate the impact of index case vaccination on SARS-CoV-2 transmission to household contacts. In our epidemiological cohort study (May 2022–November 2023), we surveyed registered index case vaccination status and test ...

@www.cidrap.umn.edu "Immunity was 81%" is such a BS phrasing without giving a time though CIDRAP! It's right in your title that waning is key!!

The article itself is SO much more accurate!

"Effectiveness rapidly declined after the previous infection, dropping from 81.3% at 3 to 6 months to 59.8% in the next 3 months and 27.5% in the 3 months after that. Protection was negligible after 1 year. Efficacy was 59.5% in the first year, plummeting to 4.8% thereafter.

Overall effectiveness against symptomatic reinfection was 45.4%, declining rapidly thereafter"

Many people only read headlines! 😦 🙃 😦
