SITE OF COVID-19 VACCINATION

Unread post by Kunle Emmanuel »

Covid-19 vaccine is given intramuscularly into the deltoid muscle.

The deltoid muscle is the muscle forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle.

It consists of three muscle heads: the anterior deltoid, lateral deltoid, and posterior deltoid.

Why give in the muscle and not somewhere else?

The strength of muscle
1) First up: unlike the layer of fat just under our skin, muscle has an excellent blood supply to help disperse the vaccine, says Joanna Groom, an immunology researcher at the Walter and Eliza Hall Institute.

2) Muscle contains and recruits immune cells called dendritic cells, which take up antigens quickly and stick them on their surface, like a flag.

Dendritic cells then migrate to and slip into lymph nodes, "which are like large meeting places for the immune system", Dr Groom says.
There, they encounter T cells and B cells — white blood cells that help defend our body against specific pathogens.
A dendritic cell will present its flag to T and B cells until it finds those that recognise the antigen, then gives them the signal to multiply and, in the case of B cells, start manufacturing antibodies.

Choice of routes of administration of vaccines is done to maximise efficiency of vaccines and to reduce significantly adverse events following immunization.

A WORD OF ADVICE TO ALL

Allow Nurses who are taught in administration of vaccines do their work to prevent vaccine errors.
Good morning all, Stay safe
