They don't count as confirmed cases unless they report symptoms and test positive for the PCR. It's in the documentation for the Pfizer and Moderna trials and reported widely in the press.
What we need to know, however, is whether there are people who test positive but do not have symptoms. That will tell us whether the vaccines prevent infection, not just symptomatic disease.
If a person has already had Covid, or been significantly exposed, and didn't get sick, I don't understand why those people need the vaccine. They fought off the disease. They are part of the herd that now has immunity. Yes, its possible to get Covid again, but the vaccine itself does not give perfect immunity either.

The vaccine would act as a booster. Anyone who has had the disease could have an antibody level checked and pass on the vaccine if antibodies are still present.

If you already had COVID-19, you might be wondering if you should plan to get vaccinated.
Doctors are still looking into how long immunity from natural infection with the coronavirus lasts, but the current thinking is that antibody levels begin to drop after a few months ― particularly in asymptomatic and milder cases ― eventually leaving people susceptible to catching the virus a second time.
Though this particular issue needs more research, health experts suspect that people with a recent COVID-19 infection may be able to hold off a few months before getting the vaccine. Those who have been recovered from COVID-19 for several months, however, should plan to get the shot as soon as it becomes available to them.
