The Mysterious Disappearance of Influenza

 CDC advisers unanimously voted to add Corona vaccines to child immunization schedules

  • The European Medicines Agency approved Pfizer/BioNTech and Moderna vaccines for use in infants in the European Union
  • Lockdowns were effective enough to hurt the slower-moving mostly harmless viruses we've lived with for centuries, but influenza disappeared in almost all jurisdictions, whether they were locked down or not
  • Seasonal outbreaks have been a regular occurrence since the 1918 pandemic

Influenza seasonality

  • Rhinovirus peaks in the fall and the spring
  • RSV and adenovirus peak around the winter solstice or just after
  • The ordinary influenza peak follows the peak of these seasonal solstice viruses
  • It looks for all the world like virus seasonality is driven mostly by two phenomena: The dark winter months, which create a greater potential for infection; and the apparent interference of viruses with each other

Flu is different from SARS-2 and ordinary human coronaviruses

  • It's also somewhat dangerous for infants and kids under four years old
  • Thus, a lot of kids get taken to the doctor every flu season
  • Young kids saw their doctors at vastly lower rates during the pandemic because influenza wasn’t around to infect them

Why did influenza disappear?

  • The pandemic was a period of atypically low infections.
  • There is an upper limit to the number of people who can fall ill at any given time, and waves of virus infection recede when they’ve reached this limit.

Second clue: the second wave peaked precisely in the solstice-virus season, where we would expect a human-infecting coronavirus to be most advantaged

  • Pre-Omicron SARS-2 appropriated flu season for itself, while remaining dominant in its own solstice niche
  • Only a minority of the population - 10% or fewer - are susceptible to respiratory virus infection at any given time
