It would appear so. Some believe the SARS, or maybe it was the MERS vaccine, which many Italians took years ago, may have made them more vulnerable to the CV.
I’ve seen that stated.
I know the poster who said it.
I’ve asked him *repeatedly* to give documentation of such.
I’ve been ignored each time.
*I* can find NO such vaccine was given *anywhere* to *anyone*.
If you have any documentation that such happened, I’d love to see it. A brand/commercial name, company that developed it, etc. Anything.
