What is an example of a cold chain breach?
A cold chain breach occurs when vaccine storage temperatures have been outside the recommended range of +2 degrees Celsius and +8 degrees Celsius. The optimal storage temperature for vaccine is 5 degrees Celsius. Many vaccines are damaged or destroyed if stored at temperatures outside this range.
What can cause a breakdown in the cold chain?
A breakdown in the “Cold Chain” occurs when vaccines are NOT stored between +2˚C and +8˚C. This can be due to delay in refrigerating vaccines once delivered, faulty fridge, electrical power cut, fridge unplugged /switched off, or fridge door left open.
What happens if a cold chain is broken?
Breaking the cold chain can lead to public health concerns, by opening the door to: The premature spoilage of merchandise. The loss of organoleptic properties (taste, appearance, etc.). And the growth of harmful bacteria and microorganisms that multiply more easily in relatively warm environments.
Which of these are common AEFI’s from the varicella vaccine?
Common AEFI Seen 7–10 days after vaccination: Fever (can be >39.4˚C), lasting 2–3 days, faint red rash (not infectious), head cold and/or runny nose, cough and/or puffy eyes. Drowsiness or tiredness. Swelling of salivary glands.
What is cold chain for vaccines?
It takes a chain of precisely coordinated events in temperature-controlled environments to store, manage and transport these life-saving products. This is called a cold chain. Vaccines must be continuously stored in a limited temperature range – from the time they are manufactured until the moment of vaccination.
Why do Asplenic individuals require extra vaccines?
Individuals should importantly should be up to date with routine vaccinations (see online WA immunisation schedule), particularly Haemophilus influenzae B (Hib), and require additional pneumococcal, meningococcal, and annual influenza vaccination, due to their increased risk of overwhelming sepsis.
Can humidity destroy vaccines?
Storing vaccines. Vaccines are fragile, biological substances. They can become less effective or even destroyed if they are exposed to temperatures outside the recommended storage range — between +2°C and +8°C.
How long can vaccines be out of the fridge for?
Once the vaccine has been opened and diluted with saline, either vials or syringes can be stored or transported at room temperatures of up to 30°C for up to six hours.
What happens if a cold chain of vaccine is broken?
Once lost, vaccine potency cannot be regained. To maintain quality, vaccines must be protected from temperature extremes. Vaccine quality is maintained using a cold chain that meets specific temperature requirements.
What are the side effects of the Pfizer vaccine?
Side effects that happen within 7 days of getting vaccinated are common but are mostly mild. Some people have side effects that affect their ability to do daily activities. Side effects (such as fever, chills, tiredness, and headache) throughout the body are more common after the second dose of the vaccine.
What is AEFI?
The new guidelines define Adverse Events Following Immunization (AEFI) as any untoward medical occurrence which follows immunization and which does not necessarily have a causal relationship with the usage of vaccines.
