One of my friends older sisters, in her late 20's came down with the flu at night, then in the morning didn't go to school (she was a teacher) b/c she was sick. She went to the hospital that evening and was dead before midnight from inflammation of the heart caused by the Flu.
We already have flu vaccines. The article is about a different type of vaccine for the flu.
In the history of vaccination, has this ever happened?
What has happened is resistance to medicine. Vaccines reduce the opportunity for pathogens to be exposed to drugs by reducing the incidence and severity of illness.
It’s fine to take time to make informed medical decisions. But if your concern is resistance, vaccines are a friend.

It seems to be related to "leaky" vaccines.
The polio vaccines aren't "leaky", but we are seeing increasing problems with oral-vaccine-derived polio now: https://www.who.int/emergencies/disease-outbreak-news/item/2... - there are more cases of this than of "wild" polio nowadays.
Non-sterilising polio vaccines prevent illness but not infection and re-transmission. OPV is the one that sterilises.
