(HealthDayNews) -- Despite promotional materials in doctors' offices reminding parents that August is National Immunization Awareness Month, only kids in high-risk categories may be able to get all or most recommended shots. Some vaccines are in short supply, the Centers for Disease Control and Prevention says.
Among the early-childhood shots that may have to be rationed are those for chicken pox, pneumonia and certain strains of flu. Supplies vary across the country, as will the lengths of shortages, the CDC says.
Late last month, the CDC anticipated shortages of some flu and pneumonia vaccines to continue at least through the latter part of the year.
