According to MIT:
Breakthrough infections: What you need to know
.....
Breakthrough infections are expected. No vaccine is perfect, but it’s useful to consider just how good these vaccines really are. It was only about 13 months ago that the FDA just released its
criteria for the development of a COVID-19 vaccine. To win approval, the agency said, a vaccine should be shown to “prevent disease or decrease its severity in at least 50% of people who are vaccinated.”
At least 50 percent efficacy. It might seem like a low bar, but that’s comparable to the annual influenza vaccine, which prevents millions of illnesses and thousands of deaths every year, even when scientists don’t do the best job of matching the vaccine to the flu viruses that end up in circulation. For example, in 2019, when the flu vaccine had an efficacy value of just
45 percent, the shot is
estimated to have prevented 7.52 million illnesses, 3.69 million medical visits, 105,000 hospitalizations, and 6,300 deaths.
Do people get the flu after getting a flu shot? Of course, and that’s expected. But if you get the flu after getting a flu shot, you’re likely to be much less sick than you would otherwise have been.
Vaccinated people are well protected from severe illness. As with the annual flu shot, people who become ill with COVID-19 after vaccination generally get a whole lot less sick than they otherwise would have been. But because the overall efficacy of the COVID vaccines is so much higher than your annual flu shot, they are much more protective against serious illness than your yearly flu shot. Even with the Delta variant.

Breakthrough illnesses are no fun, but a breakthrough infection is unlikely to land you in the hospital — or worse. According to the
CDC, as of July 26, only 6,587 vaccinated Americans had become sick enough to be hospitalized with breakthrough infections, out of more than
164 million who have been fully vaccinated. That is a breakthrough hospitalization rate of a little more than 0.003 percent. There have been 1,263 COVID-19 deaths in vaccinated individuals, representing a death rate of 0.0008 percent among vaccinated individuals.
In addition, the vast majority of those who do become seriously ill from breakthrough infections are older or have underlying medical conditions. An
Israeli study, for example, showed that 96 percent of patients hospitalized with breakthrough infections had preexisting health conditions, such as hypertension, congestive heart failure, or diabetes. And CDC data
shows that three-quarters of those hospitalized with breakthrough infections in the US were aged 65 and older. This is in line with what we’ve known all along — that certain
underlying medical conditions increase the risk of severe COVID-19 and that the likelihood of severe illness or death from COVID-19
increases steadily with age.

It appears the science does a better job against the virus than praying to magic Jesus.
