Tennessee, I am very sorry to hear about your diagnosis while glad you found us. However, as a pharmacist, I'm sure you're aware that genetically modifying viruses is a common way of producing vaccines as well as many other lifesaving applications, and that adjuvants derived from the soapbark tree, e.g. as is the one in Shingrix, are among the most common, while being continuously improved. As you no doubt also know, there are no case reports or trials to substantiate a connection.
Shingrix has been demonstrated to be a vast improvement on Zostavax's safety and efficacy as a vaccination against shingles, and shingles (which my siblings have both had) is an extremely painful and disabling illness. I would feel very badly if someone were to increase their risk based on any fear of ALS.
Best,
Laurie
