A private company is trying to outdo PFE and MRK in the very large market for vaccines against pneumococcal pneumonia, which has become even more relevant during the COVID-19 outbreak:
COVID-19 patients who were previously vaccinated with Prevnar 13 and/or Pneumovax should have a lower risk of contracting (or dying from) secondary bacterial pneumonia.
I haven't found any meaningful data as to the prevalence of secondary bacterial/pneumonia infections along with COVID-19. Have you seen any confirmed cases?
If true then perhaps Prevnar 13 use should be extended to healthcare workers and other at risk populations I qualify based on age but unfortunately have not gotten it
