Health experts speculate that reduced exposure to common pathogens during the pandemic lockdowns might have weakened children’s immune systems, making them more susceptible to infections."
In the post-mass vaccination period, I think that any speculation about the weakened innate immune response system needs to compare patient populations on a vaccinated versus unvaccinated basis. I don't buy that the weakened immune response is due to reduced exposure to pathogens. I'd be interested in reading any studies that support that claim. I think it is more likely that the mRNA vaccines play a large role in altering the innate immune response.
As I have been writing this post, I see that 'Preciouslife1' has just shared a corroborating report from the NY Post regarding an outbreak of child pneumonia in Massachusetts. He provides the following link.
I can only hope that the Novavax prototype vaccine uses the lenz cocktail, and that this protein-based vaccine becomes standard of care in the 194 countries where Novavax is approved, and that we can avoid the self-destruction which only benefits the proponents of mRNA vaccines.
