I wonder were all the Scarlett fever is coming from?
The childrens flu vaccine.

"Live attenuated influenza vaccine enhances colonization of Streptococcus
pneumoniae and Staphylococcus aureus in mice"

Our findings are, to the best of our knowledge, the first to demonstrate
that vaccination with a live attenuated viral vaccine can directly modulate
colonizing dynamics of important and unrelated human bacterial pathogens, and
does so in a manner highly analogous to that seen following wild-type virus
infection.
Importance: Following infection with an influenza virus,
infected or recently recovered individuals become transiently susceptible to
excess bacterial infections, particularly Streptococcus pneumoniae and
Staphylococcus aureus. Indeed, in the absence of preexisting comorbidities,
bacterial infections are a leading cause of severe disease during influenza
epidemics. While this synergy has been known and is well studied, what has not
been explored is the natural extension of these interactions to live attenuated
influenza vaccines (LAIVs). Here we show, in mice, that vaccination with LAIV
primes the upper respiratory tract for increased bacterial growth and
persistence of bacterial carriage, in a manner nearly identical to that seen
following wild-type influenza virus infections. Importantly, LAIV, unlike
wild-type virus, did not increase severe bacterial disease of the lower
respiratory tract. These findings may have consequences for individual
bacterial disease processes within the upper respiratory tract, as well as
bacterial transmission dynamics within LAIV-vaccinated populations.
