As with other immune-biological materials, side effects may occur with this vaccine.

Possible side effects are:

  • Stronger local reaction with the formation of ulcers (ulcers) which last longer and leave a bigger scar.
  • Stronger and prolonged reaction at the injection site  and of the regional lymph glands, which become inflamed (BCG-itis) leaving an additional scar or the process ends under the skin, and due to the accumulated calcium can be palpable.
  • Allergic reactions in the form of rash, hives, itching, anextremely rare anaphylactic reactions are also possible. 
  • Very rare reactions to the vaccine can include inflammation of the bones or joints.

There is no uniform recommendation regarding the treatment of BCG-itis. Mostly the process is just monitored and spontaneous healing occurs. Sometimes surgical drainage of the gland is done.

Distant reactions to vaccination are treated.
