Aspirating the jabs not nominally done.
The reason is to keep the vaccine out of blood stream.
Sorry for the U-tube mike but you will not hear this on CNN Fox ect.
Better explained here:
Here's the medical science on this:
Design: A systematic literature review.
A systematic approach to searching the literature was undertaken using identified academic databases from inception to May 2014. Citation searching identified additional data sources. Six studies met the search criteria.
The majority of health professionals do not aspirate for the recommended 5-10 seconds. Administering an injection faster without aspiration is less painful than injecting slowly and aspirating. The main influences on the decision of whether or not to aspirate are based on what health professionals are taught and fear of injecting into a blood vessel.
Conclusions: In the paediatric vaccination setting, the practice of aspirating during the administration of an intramuscular injection is unnecessary and there is no clinical reason to suggest that these principles may not be applied when using the deltoid, ventrogluteal and vastus lateralis sites in other settings. Owing to its proximity to the gluteal artery, aspiration when using the dorsogluteal site is recommended. Nurses must be supported in all settings, by clear guidance which rejects traditional practice and facilitates evidence-based practice.
Relevance to clinical practice: Educators need to ensure that their knowledge is up to date so that what they teach is based on evidence. This may be facilitated via regular educational updates. Further research and subsequent guidance are needed to support evidence-based practice in intramuscular injection techniques in all nursing settings.
There is a shortage of consistent recommendations regarding aspiration before injection in published literature, regulatory guidelines, and medical and nursing school curricula. There is also no central and easily accessible place where one can access and review information and guidelines regarding the procedure. It is therefore important to bring all the evidence, published and otherwise, to the forefront for clinicians, researchers, regulatory bodies and device manufacturers so that they can make an informed decision. Based on our findings, the need for aspiration prior to administering an injection is dependent upon multiple factors. Systemic adverse effects profile and mode of delivery (IV vs IM and SC) of drugs plays a significant role in the decision to aspirate or not to aspirate. There is ample evidence that suggests that aspiration may not be required for IM and SC injections, while for IV injections the systemic side effects of the drug should be considered when aspirating before any injection.
Do you need to aspirate when giving
intramuscular (IM) injections?

Take home: aspiration is NOT needed for IM injections if proper technique and
location is used EXCEPT for the dorsogluteal site where it should be used.

It is common practice to draw back on a syringe after the needle is inserted to check whether it is in a blood vessel. While it is important to aspirate if the DG muscle site is used – because of proximity to the gluteal artery – it is not required for other IM injection sites (PHE, 2013; Malkin, 2008).
Dr. Ebraheim’s educational animated video describes the deltoid intramuscular injection, which is a common procedure.
This relates to your video cutworm. It won't allow me to copy much text but you can read it below. This would apply to all intra-muscular deltoid injections.
