Oh please. Are you seeing reports in the news about rising numbers of reinfections? Or are you seeing more reports about breakthrough cases? I already know the answer. The CDC stopped counting breakthrough cases. Why you ask? They are afraid that if the numbers are reported, it may cause more resistance to getting vaxed. But the truth always comes out.
They New York Times did some research on breakthrough rates in the states that actually keep good records of this. Here is what they found:
To better understand the rates of infection in fully vaccinated people, The Times collected data from seven states—California, Colorado, Massachusetts, Oregon, Utah, Vermont, and Virginia—selected for keeping particularly detailed records. Analysis showed that in six of the states, breakthrough infections made up 18 to 28 percent of all newly diagnosed cases of COVID-19 in the past several weeks. Results also found that fully vaccinated people made up 12 to 24 percent of all COVID-related hospitalizations, and while the number of deaths was too small to be considered significant, it is likely higher than the original Centers for Disease Control and Prevention (CDC) estimates of .5 percent.

Study: Natural immunity 'stronger, longer' than vaccine immunity
New Israeli study shows recovered patients tended to have better outcomes than vaccine alone - though vaccine can enhance natural immunity.
A new Israeli study on coronavirus immunity suggests that people who were previously infected with the virus benefit from significantly stronger and longer-lasting immunity than the immunity provided by vaccination alone.
The study, a retrospective observational study conducted by Maccabi Healthcare Services, Tel Aviv University, Ashdod University Hospital, compared Israelis from three groups: people who had received vaccine and were never infected (SARS-CoV-2 naïve), people who were previously infected and did not receive the vaccine, and people who were infected with SARS-CoV-2 and then vaccinated after recovering.
Researchers found that natural immunity is stronger and longer-lasting than vaccination, but also noted that a single-dose of vaccine likely can offer additional protection from the Delta Variant to those who recovered from SARS-CoV-2.
For the study, researchers analyzed anonymized Electronic Health Records, a database which covers records for 2.5 million people in Israeli, spanning March 1st 2020 to August 14th 2021.
The study grouped the subjects into categories based on vaccination status and previous infection, correcting for demographic factors including age, sex, location of residence, as well as the timing of infection or vaccination.
In the first analysis, which only compared natural immunity to vaccinated immunity among the SARS-CoV-2 naïve, two cohorts of 16,215 people each were studied, with equal representation of age, sex, location, and time of infection or vaccination.
This model showed 256 total cases of infection, 238 were ‘breakthrough infections’ of the vaccinated and COVID naive, while 19 were reinfections among the unvaccinated, previously infected group. Adjusting for comorbidities, vaccinated COVID-naïve people had 13 times greater risk for infection than did the previously infected.
Of 199 symptomatic cases, 191 were among the vaccinated, just 8 were among the previously infected. After adjusting for comorbidities, researchers found the vaccinated were 27 times more likely to suffer a symptomatic case of the virus in comparison to the risk previously infected people had of having symptomatic reinfection case.
A total of nine hospitalizations were reported, eight of them among the vaccinated COVID-naïve group, with one among the previously infected. No deaths were reported in either cohort.
