WHO Estimates The XE Subvariant More Transmissible Than Even BA.2
This should hold true if we are building natural immunity to a natural virus. But the UK has reported those with prior COVID-19 infection are about 15% more likely to develop a second Omicron infection. Whether this is evidence of a failure of natural immunity, a lab-made virus that manages to evade immunity or fallout from vaccination ("original antigenic sin") is unclear. Perhaps the missing context is to compare how often other respiratory viruses reinfect the same individual in the same season/year? White House Press Sec. Jen Psaki recovered from COVID-19 some months ago but was recently reinfected despite being fully vaccinated and boosted. She is by no means elderly and to the best of anyone's knowledge is not immunocompromised so what accounts for this? And to that end, is the CDC keeping statistics on reinfection rates?
Much confusion exists around why the CDC refused to acknowledge natural immunity on par with or better than that created via vaccination. One theory was that the CDC/FDA were intent on helping Pfizer and Moderna sell more vaccines. However, deviation from public health norms — i.e. recognition of natural immunity following infection, with some notable exceptions for HIV, malaria and similar viruses — would make sense if the CDC/NIH knows something about the origins/nature of this virus that the public does not. If, for example, COVID-19 is a product of gain-of-function research can we assume natural immunity will be durable or that that COVID-19 will attenuate into something harmless? Further complicating matters, leaky vaccines have been joined by leaky antiviral medications that promote the evolution of more, not less variants — at the added risk of more virulence. What the future holds is, unfortunately, anyone's guess.
