The Centers for Disease Control and Prevention is warning about the dangers of injecting cold medicine.
The CDC said it is working with states to develop policies and procedures that will prevent cold medicine from being used as a form of immunization.
It said the agency is also working with vaccine manufacturers and health care providers to develop guidelines for administering the cold vaccine.
“The best way to protect the public from a potentially harmful vaccine is to avoid injecting cold-related products, especially in cases where it is possible to get cold,” said Dr. Anthony Fauci, CDC director.
He added, “The CDC will continue to work with states and other federal agencies to ensure they are doing everything they can to minimize the risks.”
The CDC is also encouraging people to get vaccinated.
The agency has issued an alert for adults who are at risk of becoming sick with the cold and the flu.
It is also urging people to avoid sharing needles with children and to get tested for the virus.
The cold is contagious through direct contact with the virus or through coughing, sneezing or sneezes.
Symptoms include a mild fever, sore throat, runny nose and cough.
It can cause coughs, shortness of breath and fatigue.
The flu can be mild and spread easily from person to person.
The U.S. Centers for Medicare and Medicaid Services said the CDC recommends adults get tested annually for the flu, and those who are likely to become ill should get tested.
