The case rate among fully vaccinated is very, very low.
COVID-19 Vaccine Breakthrough Cases: Data from the States | KFF
To quote from the above link:
Overall, we find that:
Half of states (25) report some data on COVID-19 breakthrough events (see Table 1). Twenty-four provide data on breakthrough cases, 19 on hospitalizations and on deaths.
Fifteen of these states regularly update these data, often on a weekly basis. The rest use a different frequency, have one-time reports, have stopped updating, or have an unclear reporting frequency.
The data reported from these states indicate that breakthrough cases, hospitalizations, and deaths are extremely rare events among those who are fully vaccinated against COVID-19 (see Figure 1). The rate of breakthrough cases reported among those fully vaccinated is well below 1% in all reporting states, ranging from 0.01% in Connecticut to 0.29% in Alaska.
The hospitalization rate among fully vaccinated people with COVID-19 ranged from effectively zero (0.00%) in California, Delaware, D.C., Indiana, New Jersey, New Mexico, Vermont, and Virginia to 0.06% in Arkansas. (Note: Hospitalization may or may not have been due to COVID-19.)
The rates of death among fully vaccinated people with COVID-19 were even lower, effectively zero (0.00%) in all but two reporting states, Arkansas and Michigan where they were 0.01%. (Note: Deaths may or may not have been due to COVID-19.)
The surge in COVID is occurring among the unvaccinated.
The solution to COVID, and getting back to life as “normal” is: Get vaccinated.
