That's weird. Because it's the same shot twice. At work my entire team has had the pfizer vaccine (Noone sick). A few vaccines have a two shot dose. Is this like the flu shot gives you the flu type of FUD?
No, it's like the “shot designed to produce an immune reaction gives you an immune reaction” story. Which is true. Also true for the flu shot.
Which doesn't give you the flu, but can give you (shorter-lived, milder) flu symptoms, because “flu symptoms” are mostly symptoms of the immune response to the flu.
I know around 20 people who have gotten the vaccine and this is consistent with what they experienced too. Most of them reported some flulike symptoms that were somewhat worse than the flu shot.
