If there have been 5800 covid cases after vaccination, then is likely it is actually at least double?

I know we can’t know for sure, but assuming there are asymptomatic cases, then I would think it is actually more than 5800. Have you read or heard anything about that? If most people around the asymptomatic person are vaccinated then it would not start a new cluster of the virus.

Also, do you know how many breakthrough cases were Moderna, Pfizer, or J&J? How about the age breakdown of the people who had breakthrough cases?
