you can always catch an illness from a child but most of these are viral (like colds). your pneumonia shot only protects you from certain types of bacterial pneumonia (pneumococcus). it would not protect you at all from viruses. any respiratory virus can cause pneumonia or sinusitis if you are prone to these types of infections.
i have had a pneumonia shot can i get either a sinus infection or walking pneumonia from my 6 year old grand daughter? . and can i be a carrier to others in my age group?
