Hi all. Welcome to the Summer 2020 roundup of the latest news, articles, and information about Shoulder Injury Related to Vaccine Administration (SIRVA). I hope everyone is making it through this trying time.
I have seen several articles recently about coronavirus and the immune system, with speculation about why women are getting hit less hard than men. They invoke something which I have seen before, which is the evidence suggesting that women’s immune systems on average mount a more vigorous defense to invaders than men’s. (This is also suggested as one of several reasons that autoimmune disease is much more common in women.) I wonder if it is also part of the effect that SIRVA happens more frequently to women than men, in addition to the smaller average shoulder, arm, and deltoid size. It’s speculation, but interesting, and I’m seeing it in the news lately with respect to covid-19.
Anyway, on to SIRVA-related news:
New SIRVA Research
This comes from a nontraditional medical journal, but I’m including it for completeness:
This article is a data analysis of the frequency of subdeltoid bursitis following flu vaccination (one particularly common SIRVA injury). Their finding is that there are 7.78 additional cases of bursitis per 1 million persons vaccinated, although this relies on reported cases of SIRVA where some cases may still go unrecognized or incorrectly diagnosed:
And related editorial:
Both of the preceding two articles are behind a paywall other than their summaries, but let me know if you would like a copy.
This article was (to me) a fascinating read that intersects the vaccine court, the flu vaccine, and coronavirus misinformation: “The Star of ‘Plandemic’ Spent Years Flooding the Vaccine Court System with Bad Science“.
Here’s an article (pdf) out of Victoria, Australia, that briefly mentions SIRVA. It says that because SIRVA cases were perceived to increase in 2018, their Advisory Committee on Vaccines was alerted and new resources were developed, including a “national educational initiative on correct injection technique”. Sounds like an appropriate response!
This educational research article (pdf) is not related to why SIRVA happens or how to treat it, but I enjoyed reading about training pharmacists to safely administer vaccines (and avoid SIRVA) using an “augmented reality” (Microsoft Hololens) simulation, among other techniques (like learning on a mannequin). Because the place to stop SIRVA from happening is in training the people who give vaccines, I’m always interested in what programs are doing to step up their game.
