For those in whom the characteristic redness appears, and who are
therefore known to be liable to catch diphtheria, doctors now advise a
course of protective injections similar to those which have proven so
successful against typhoid fever. This protective treatment consists of
three small injections, a week apart. There is no sore, as there is in
smallpox vaccination, and the injections are harmless. The protection
lasts for years, and perhaps even for life.
Why not have the doctor make a Schick test on your child, and if this
shows the lack of protection against diphtheria have him give the three
protective injections?
