CDC data "shows" vaccines 5x more effective than prior COVID-19 infections

This is the study the Superintendent of Health in Malta is using to justify vaccine mandates:


"Among hospitalized patients, the agency found that those who had gotten two shots of the Moderna or Pfizer vaccine were less likely to test positive for COVID-19."

"These findings suggest that among hospitalized adults with COVID-19-like illness whose previous infection or vaccination occurred 90-179 days earlier, vaccine-induced immunity was more protective than infection-induced immunity against laboratory-confirmed COVID-19," said study authors."

"WHY IT MATTERS

The agency used data from 187 hospitals in the VISION Network, which includes Columbia University Irving Medical Center, HealthPartners, Intermountain Healthcare, Kaiser Permanente Northern California and Northwest, Regenstrief Institute, and University of Colorado.

By examining data from adults hospitalized between January and September 2021, it compared the odds of testing positive for COVID-19 among adults who had not received an mRNA vaccine, but who'd had a previous novel coronavirus infection, with individuals who had gotten two Pfizer or Moderna shots.

The chances of testing positive for COVID-19 were 5.49 times higher among the former group.

The benefits of vaccination in this particular study appeared to be higher for Moderna recipients and for those older than 65. The agency noted several limitations, including potential misclassification of patients and selection bias.

The study only examined adults who had tested positive more than three months prior to their hospitalization in order to reduce the chances that their illness was related to an ongoing infection rather than a new one.

It also did not include those who had received only one mRNA vaccine dose, those who obtained their second shot less than two weeks before hospitalization or those who received the Johnson and Johnson vaccine.

In addition, wrote researchers, "These results might not be generalizable to nonhospitalized patients who have different access to medical care or different healthcare-seeking behaviors, particularly outside of the nine states covered."

Overall, they said, the messaging remains consistent:
Everyone eligible should get the vaccine – including those who have already had COVID-19."

I went to look up for counterpoints online and found a good study explanation here:

I don't know if OP was referencing the tables below, but in Table 1, 1,020 non-inoculated persons were hospitalized with COVID-like illness compared to 6,328 fully inoculated persons being hospitalized with COVID-like illness. Out of the patients who had tested positive for COVID, 89 of them were non-inoculated while 324 were fully inoculated. Regarding age groups, more people were hospitalized with COVID-like illness in the fully inoculated group versus those in the non-inoculated group, especially patients aged 50 and up.
In Table 2, for the section, "Any mRNA vaccine, no restriction of time since previous infection or completion of vaccination," 18,397 fully inoculated persons were hospitalized with COVID-like illness with 542 of them testing positive for COVID. In the non-inoculated group, 2,085 of them were hospitalized with COVID-like illness with 130 testing positive for COVID. For the section, "Any mRNA vaccine, examining the potential influence of time since previous infection or completion of vaccination," 12,231 fully inoculated persons were hospitalized with COVID-like illness with 448 of them testing positive for COVID. In the non-inoculated group, 1,389 of them were hospitalized with COVID-like illness with 107 testing positive for COVID.
For the section, "Before Delta predominance (January–June 2021)," 1,115 fully inoculated persons were hospitalized with COVID-like illness with 18 of them testing positive for COVID. In the non-inoculated group, 831 of them were hospitalized with COVID-like illness with 70 testing positive for COVID. However, for the section, "During Delta predominance (June–September 2021)**," 5,213 fully inoculated persons were hospitalized with COVID-like illness with 306 of them testing positive for COVID. Moreover, in the non-inoculated group, 189 of them were hospitalized with COVID-like illness with 19 testing positive for COVID.
For the section, "By age group, yrs: 18-64," 1,425 fully inoculated persons were hospitalized with COVID-like illness with 71 of them testing positive for COVID. In the non-inoculated group, 556 of them were hospitalized with COVID-like illness with 49 testing positive for COVID. For the section, "By age group, yrs: greater than or equal to 65," 4,903 fully inoculated persons were hospitalized with COVID-like illness with 253 of them testing positive for COVID. In the non-inoculated group, 464 of them were hospitalized with COVID-like illness with 40 testing positive for COVID.
From the above, the CDC was more concerned with ratios rather than the number of patients who were hospitalized with COVID-like illness and had tested positive for COVID based on their COVID inoculation status.

Though the study also easily becomes bunk while taking into account that the CDC has guidelines to test vaccinated people differently from unvaccinated people:

The study compared the number of COVID-infected people in each group to the number who had had a documented prior infection (unvaccinated group) or fully vaccinated 90-179 days prior. This is a weird study design to begin with since it bears no relevance to the general population. They should be looking at how many previously-infected and previously-vaxxed people at the hospital there were compared to vaccination rates in the geographic areas from which those infected people came from.

The raw data also show that more vaccinated were reinfected than naturally immune, 324 to 89. Even after converting to percentages, the naturally immune group show a 9% reinfection rate while the vaccinated group showed 5.5%. This is a ratio of 1.7, not the claimed 5.49. They get the 5.49 by doing manipulation and adjustment for socioeconomic factors and other B.S.

On top of that, the study doesn’t take into account re-infection rates in the general population, but only in those who were sick enough to show up at hospital.

The number of people with a prior infection is also suspiciously low, almost certainly too low. 1000 out of 200,000 is about 0.5%. Way more people than that have already had SARS2. That number should be at least 20%, so more like 40,000 or higher.
