What is in Vaccines?
Vaccines only use the necessary ingredients that they need to be as safe and effective as possible. The only ingredients used provide immunity, keep the vaccine safe and long lasting, and are there for the production of the vaccine
Is it safe to get multiple vaccines at once?
Scientific data shows that getting several vaccines done at the same time does not cause chronic health problems. Certain combinations of vaccines can cause fever, and occasionally febrile seizures. Talk to your doctor for more information regarding multiple vaccines.
What do I do if a vaccine is recalled?
In many cases, a person who has been vaccinated will not need to do anything if that vaccine is recalled. If the recall is due to low potency or strength, the person may need to be vaccinated again. If it is recalled due to a possible safety concern, the person should be aware of their reaction and talk to their doctor if concerned.
How does the CDC's Immunization Safety Office monitor the safety of vaccines?
- Vaccine Adverse Event Reporting System (VAERS): An early warning system to which anyone can report suspected vaccine reactions and issues.
- Clinical Immunization Safety Assessment (CISA) Project: Clinical research on vaccine-associated health risks in certain groups of people conducted by CDC and several medical centers.
- Vaccine Safety Datalink (VSD): Ongoing monitoring and proactive searches of vaccine-related data conducted by CDC.
Emergency Preparedness for Vaccine Safety: CDC can activate emergency preparedness activities to ensure that vaccines remain safe in the event of a disease outbreak where mass vaccination is necessary.
