Why do vaccines need to be reconstituted?
To minimize loss of vaccine potency, healthcare staff should reconstitute a vaccine just before administering it. Some vaccines must be discarded unless they are given immediately or within 30 minutes after they are reconstituted. Each vaccine’s package insert gives detailed instructions for reconstituting the product.
When should vaccines be reconstituted?
Because: Reconstituted vaccines should be used as soon as possible after mixing and discarded within 6 hours.
How do you dilute a vaccine?
Use 0.9% sodium chloride (normal saline, preservative-free) ONLY. Mix 1.8 mL of the diluent with the thawed vaccine. * Slowly inject diluent to prevent excess foaming or bubbling. Gently invert the vial 10 times before and after adding the diluent.
Who is responsible for correct storage of vaccines?
It is the responsibility of the person transporting and administering vaccines to assure themselves that the vaccine has been stored between 2-8°C prior to administration. This includes staff administering vaccines to patients outside of the practice, for example in their own home/care home setting.
How do you mix MMR?
Single Dose Vial — First withdraw the entire volume of diluent into the syringe to be used for reconstitution. Inject all the diluent in the syringe into the vial of lyophilized vaccine, and agitate to mix thoroughly. If the lyophilized vaccine cannot be dissolved, discard.
Why is BCG given at birth?
Background. In most tuberculosis (TB) endemic countries, bacillus Calmette Guérin (BCG) is usually given around birth to prevent severe TB in infants. The neonatal immune system is immature.
How many vaccines can be given at once?
There is no upper limit for the number of vaccines that can be administered during one visit. ACIP and AAP consistently recommend that all needed vaccines be administered during an office visit. Vaccination should not be deferred because multiple vaccines are needed.
What documents do you need to give vaccines?
Federal requirements mandate that you document five things when you administer a vaccine:
- The name of the vaccine and the manufacturer;
- The lot number and expiration date of the vaccine;
- The date of administration;
- The name, address, title and signature (electronic is acceptable) of the person administering the vaccine;
How can freezing damage vaccines?
Effectiveness cannot be guaranteed for vaccines unless they have been stored at the correct temperature. Freezing may cause deterioration of the vaccine and lead to hairline cracks in the ampoule, vial or pre-filled syringe which could potentially allow the contents to become contaminated.
Which vaccines are easily damaged by freezing?
Some of the most widely used vaccines are freeze-sensitive, including:
- Liquid Haemophilus influenzae type b (Hib)
- Hepatitis B.
