This is where it should be placed!
Proper placement of the vaccine is critical to the effectiveness of the vaccine AND to avoiding injury.
In other words, that vaccine must be placed smack dab in the middle of that Deltoid Muscle - where the muscle is the thickest. Highly vascularized MUSCLE absorbs the vaccine into the VASCULAR system, rapidly. If the vaccine is placed too low on the arm, the vaccine may be being inserted into the tendinous insertion of the muscle (the tendon) - NOT THE MUSCLE ITSELF. This hurts; this causes injury to the tissues; and the vaccine is NOT effective. |

Notice that the injection site is BELOW the Deltoid Muscle. This is being injected into the tendinous insertion of that muscle. This hurts; this can cause a serious injury; and the vaccine is NOT effective. |

Where is the correct anatomical spot for any IM (IntraMuscular) vaccine?
How do you determine where that spot is?
How do you determine where that spot is?

Instructions:
You MUST first find the anatomical landmarks of the Deltoid Muscle: Origin / Belly of / Insertion.
The INSERTION will feel flat and hard - it is - it is a flat tendon. [SAA] The BELLY will feel soft, pliable, an in the center it feels THICK. [It is thick, the thickest part of the muscle. And that muscle is highly vascularized. That's why muscle is red, has lots of blood, has lots of circulation, has lots of 'UPTAKE / absorption capability. 2. Once you have located the ORIGIN and the INSERTION, now you LOOK at your two landmarks and 'eyeball' the half way mark in - between them - dead center on the muscle mass. THAT is where the immunization is given. |
Last but NOT least......
You MUST select the appropriate
You MUST select the appropriate
- needle gauge for the viscosity (thickness) of the biological (vaccine), and the
- needle length for thickness of the muscle mass.
Rule of thumb:
Vaccine viscosity (thickness) is always the equivalent of H2O (water). The vaccine fluidity is very thin.
Therefore, a very thin (small) needle will work. 27g-29g.
No need to create a bigger hole, if you don't have to.
The Insulin Syringe is great!
Muscle mass will determine what length needle you should be using for the injection.
The smaller muscles (average females/older humans) have thinner muscles.
These muscles may only be an inch and a half thick.
Use a 1/2 inch needle.
The Insulin Syringe is great for that!
The larger Deltoids (bigger men/athletes) have thicker muscles.
These muscles can tolerate and will need a longer needle.
Use the 1 inch needle.

Vaccine must be placed in the center of the muscle mass to be properly absorbed & to avoid injury to the muscle.
Centered from top - bottom.
Centered from the "inside" - "outside".

If the vaccine is NOT properly placed and injected...
there is pain,
there is tissue injury,
there is interference with vaccine uptake.
The vaccination will not be a good experience
or have a good outcome
- for anyone.
Tip 1: Needle Insertion
Bevel up; 90 degree angle; set the needle to the skin (actually touch), then IN (insert), stabilize the needle; depress the plunger - DONE.
Tip 2: If the sleeve can't be moved all the way up to the TOP of the shoulder, the arm must come out of the sleeve.
The entire Deltoid should be exposed/VISUALIZED to be able to clearly see & feel the Origin, Belly, and Insertion of the muscle; to be able to place the vaccine in the middle of the muscle.
Do it RIGHT, or don't do it.
