Results:
SARS-CoV-2-naïve vaccinees had a 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021. The increased risk was significant (P<0.001) for symptomatic disease as well. When allowing the infection to occur at any time before vaccination (from March 2020 to February 2021), evidence of waning natural immunity was demonstrated, though SARS-CoV-2 naïve vaccinees had a 5.96-fold (95% CI, 4.85 to 7.33) increased risk for breakthrough infection and a 7.13-fold (95% CI, 5.51 to 9.21) increased risk for symptomatic disease. SARS-CoV-2-naïve vaccinees were also at a greater risk for COVID-19-related-hospitalizations compared to those that were previously infected.
Conclusions:
This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SuARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity. Individuals who were both previously infected with SARS-CoV-2 and given a single dose of the vaccine gained additional protection against the Delta variant.
The largest real-world analysis comparing natural immunity -- gained from an earlier infection.

I keep posting this stuff so studies can be compared with the narrative. Also, keep in mind that these low percentages are done in a lab setting with the virus being shot at the mask. The mask also is the correct size for sealing; the mask is not constantly touched, the mask has not been saturated with vapors from breathing, and the mask is new, not reused daily.
An analysis by mask use showed ILI (RR=6.64, 95% CI 1.45 to 28.65) and laboratory-confirmed virus (RR=1.72, 95% CI 1.01 to 2.94) were significantly higher in the cloth masks group compared with the medical masks group. Penetration of cloth masks by particles was almost 97% and medical masks 44%.

The results show that a standard surgical and three-ply cloth masks, which see current widespread use, filter at apparent efficiencies of only 12.4% and 9.8%, respectively. Apparent efficiencies of 46.3% and 60.2% are found for KN95 and R95 masks, respectively, which are still notably lower than the verified 95% rated ideal efficiencies.

I want to share studies and research so parents can be informed on the possible dangers of mask use. Remember we also have no long term studies on wearing masks for hours a day.
In a new study published by The Journal of the American Medical Association (JAMA), entitled “Experimental Assessment of Carbon Dioxide Content in Inhaled Air With or Without Face Masks in Healthy Children,” Polish researchers found that within just three minutes, the level of carbon dioxide present in the air being breathed in by school children wearing masks was six times higher than the legal limit of 0.2% carbon dioxide by volume (2,000 parts per million), as set by the German Federal Environmental Office. In open-air settings, CO2 levels are about 0.04% by volume, or 400 parts per million.

It seems to be that masks are only effective when used in professional or controlled lab settings. In the general population within covid surges they did little to no good. Why? Is it because the people would rather risk the virus than wear a mask? Does the general population see it as tool for tyranny? Does the majority of the population wear the wrong masks? Don't properly dispose of them? Don't change or wash them as necessary? Constantly shifting and touching them? Wearing them the wrong way? Can't breath in them?
For some reason the masks by current studies suggest they work but only if worn by a professional, the correct type of mask or in controlled lab setting.
Mask mandate and use efficacy in state-level COVID-19 containment
Damian D. Guerra, Daniel J. Cierra

Conclusions Mask mandates and use are not associated with slower state-level COVID-19 spread during COVID-19 growth surges. Containment requires future research and implementation of existing efficacious strategies.

How effective is a mask in preventing COVID‐19 infection?

Based on these studies, all people, regardless of physical conditions and professions, should wear masks at all times in prevention of COVID‐19.

An Israeli case study conducted by researchers at top Ivy League universities appeared to confirm that natural immunity was 27 times more effective than
vaccines at preventing symptomatic transmission of the deadly
coronavirus.
“This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant,” they wrote, according
to medRxiv.
