Merchants of herd death oversold immunity. People are being reinfected immediately again after Omicron infection.

We have the data: Both laboratory experiments and actual cases.

1/ Image
Evidence from a study showing immunity based upon “mild" Omicron infection is weak for Omicron reinfection, and limited for cross immunity to Delta infection.

2/
 medrxiv.org/content/10.110… Image
Overall, immunity from Omicron infection is much lower than the immunity from Delta infection, correlated with the severity of infection. So unless you get a severe infection with all of its consequences you also don’t get immunity from having another infection.

3/
And recall even immunity from severe infection wanes rapidly in a few months.

4/
Summary: "Neutralizing immunity...from Omicron and Delta"

"We found a significantly smaller rise of neutralization titers associated with milder Omicron breakthrough infection in vaccinated individuals, to only approximately one-third of the rise associated with boosting.

5/
"We also identified limited cross-variant immunity to Delta."

6/
"Thus, breakthrough infection from Omicron may enhance cross-protection against Delta, and vice-versa, [only] inasmuch as there is a sufficiently large increase in baseline neutralizing immunity, which appears to be related to the clinical severity of the infection.

7/
"Our findings parallel those from another study from our group that demonstrated limited cross-variant immunity after milder Omicron variant infection in unvaccinated individuals in a mouse model and in human patients.

8/
"Taken together, our results suggest that Omicron-induced immunity may not be sufficient to prevent infection from another, more pathogenic variant, should it emerge in the future.

9/
Actual cases of reinfection by Omicron are so widespread they are manifest to anyone who is not closing their eyes:

Important addition:

Anthony Leonardi @fitterhappierAJ has shown that the immune system T-cells are damaged by covid (shades of HIV), potentially undermining not just Covid immunity but immunity to other diseases, and part of Autoimmune dysfunction after covid.

Thread: Public Comment on HICPAC Concerns 🧵

1/ I’m here not to address HICPAC directly, but to speak to those listening—healthcare professionals, patients, and advocates—who are committed to public health and safety.

Let me highlight several critical concerns.
2/ Members of HICPAC and the organizations they represent have significant financial conflicts of interest.

This issue, documented in a complaint submitted to the HHS Office of Inspector General, raises serious questions about the integrity of their guidance.
3/ Additionally, HICPAC has operated in secrecy, with workgroup meetings closed to public scrutiny.

This violates the Federal Advisory Committee Act, which mandates transparency. Such closed-door decisions erode trust and undermine accountability.
