Tucked away in the following article is some actual data about breakthrough infections.

"Of the 95 million people fully vaccinated in the US until 26 April, 9,045 developed breakthrough infections, according to the Centers for Disease Control and Prevention (CDC).
Eight hundred and thirty five (9%) were hospitalised and 132 (1%) died. Nearly a third of the hospitalised patients and 15% of the deaths were reported as "asymptomatic or not related to Covid-19"."
The way the present the percentages (as a percentage of the people re-infected is of course designed to be sensationalist.
If you take the numbers of people hospitalised/fatalities as a percentage of the 95m people fully vaccinated (and strip out the cases not related to covid) the odds are infinitesimal. approx 1 in 10,000 get a breakthrough infection, less than 1 in 100,000 end up in hospital and slightly over 1 in a million unfortunately die.
