Multi-Dose Vial Safety Reminders for National Immunization Awareness Month
Posted on by
August is National Immunization Awareness Month, an observance to acknowledge the importance of routine vaccination for people of all ages. Project Firstline wants to ensure that all healthcare workers who give vaccines understand the importance of safe injection practices, and that they use multi-dose vaccine vials safely and correctly.
A multi-dose vaccine vial is a vial of liquid medication that contains more than one dose of medication. Many vaccines come in small bottles with more than one dose of vaccine inside of them. These multi-dose vaccine vials are used multiple times to vaccinate multiple people with a fresh needle and fresh syringe every time. A specific set of safety procedures are required and should be used every time a vaccine is prepared and given to help ensure they don’t become dirty and possibly harm people. Here are 10 injection safety steps to remember when working with multi-dose vaccine:
- Always prepare injections away from patient care spaces in a clean designated area. Preparing multi-dose vials in a separate space helps ensure they are handled correctly and decreases the chance for mistakes.
Clean your hands before touching the vial. Germs from your hands could get on or inside the vial and contaminate the vaccine as well as put the patient at risk for infection.- Check the label to make sure it is a multi-dose vaccine vial. If it’s not, the vial should only be used once for a single patient. Next, confirm the vaccine is not expired. Expired vaccines may not work as well and should not be used.
- Make sure the vaccine appears the way the vaccine maker tells you it should. If it doesn’t or you’re worried something has gotten inside the vial, don’t use it. You can check the instructions from the vaccine maker to find out what the vaccine is supposed to look like. Any unusual color or cloudiness is cause for concern because it could be contaminated.
- Use brand-new, sterile needles and syringes for every vaccine dose. Just using a new needle is not enough because if the syringe has been used, blood can get into the vial when you draw up the vaccine. Even if the syringe looks clean, you could risk the spread of viruses like hepatitis C or HIV.
- Disinfect the top part of the vial (the vial stopper) with an alcohol prep pad every time you draw up a vaccine. Germs can live on the top of the vial. If it’s not clean, germs can get pushed into the vial when you insert the needle into it, contaminating the vaccine inside. Those germs could be then injected into patients and make them sick.
- Let the vial stopper dry completely before you stick the needle in to draw up a dose of vaccine. This gives the alcohol time to kill any germs that may be on top of the vial.
- As soon as you draw up the first dose, write the date and time on the label indicating when the vial was opened. Follow your facility’s policy or the manufacturer’s label instructions to prevent the vaccine from being given to patients beyond its use date.
- Follow the vaccine maker’s instructions for storage and for how long you can use the vaccine after you first access the vial, which varies by product. Beyond-use or improperly stored vials must be thrown away.
- Never “pool” doses. Combining partial doses from multiple vials to make one dose for a patient could increase the risk of germs or other contaminants getting into the vaccine.
Injection safety is an important element of Standard Precautions and should be used in all healthcare settings with all patients or residents to prevent the spread of germs, including bloodborne pathogens like hepatitis B and C. Using multi-dose vaccine vials safely ensures that your patient gets the full benefit of the vaccine without being harmed by the injection.

I really like the information provided in the above article. A nurse in Medintu uses gloves and a mask before using the syringe at home for eaderly care of people for moe information you can visit our site https://medintu.in/home-care-services-in-hyderabad/
Nice Article . Important to note that adhering to aseptic technique during vial preparation and administration is non-negotiable. Maintaining sterility helps prevent infections. If you are interested to know more Esketamine Treatment
Thank you for highlighting the significance of multi-dose vial safety. These vials can be convenient, but they also require careful attention to prevent contamination and ensure accurate dosing. By reinforcing safe practices, we not only protect patients but also contribute to the Mental health of those responsible for administering medications.
What is the recommendation for storage and handling single patient multi-use medications such as Metered Dose Inhalers in the hospital setting? What are the best practices for Respiratory Therapist delivering these medications?
I have seen multiple doses of flu vaccine and Covid vaccines drawn up and refrigerated by one nurse and used by multiple other nurses. I appreciate the comments of your article and recommendations but when you are dealing with large groups of people some suggestions are not practical.
Excelente información de vital importancia.
After 40 years working in injection safety and vaccine-preventable diseases, I would be interested in your data supporting your recommendation that doses should be prepared in a separate area away from the place where they will be injected. In my career, I have seen many errors in which one person draws up the vaccine dose and a second administers the wrong dose. People also recap the syringe after drawing it up, which increases the risk of contaminating the needle or getting a needlestick. It also means that the person administering the dose can not verify what vial it came from, what the vial looked like, or if it came from a single-dose or expired vial. Labeling each syringe is also error-prone and often unintelligible.
I think it is a better practice to have the same person draw up and administer the dose. In high-volume EPI campaigns overseas, a small team can give 2500 doses in a day and still draw up their own doses. In those contexts, it is also important to have the administrator check the vaccine vial monitor.
Otherwise, thank you and your team for your work in injection safety.
I really like this!! I will be sending to all of the IPs in our Company and will encourage them to use the Injection steps as part of their infection control and prevention education for this month.
A nurse using multiple doses vial must wear gloves and mask before using the vial and syringe .
Thanks
