The field data cited is not independent since it is tainted by bias and money interests. Natural immunity stops covid spread in its tracks.
Not true. People can and have gotten covid more than once. If immunity from having the disease was so much more effective, they could only get covid once. In fact both vaccine immunity and "natural" immunity wane at about the same rate.
Infection can be reduced via Iodine nasal spray 2 times a day.
It's not clear where the idea that Betadine (povidone-iodine) could potentially prevent COVID-19 came from. There appears to be no reliable data that suggests that povidone-iodine can help prevent COVID-19 or its spread, Cassandra M. Pierre
, MD, MPH, an infectious disease physician and the medical director of public health programs at Boston Medical Center, told Health
in September 2021. However, research concerning its efficacy has been growing but mixed.
The efficacy of PVP-I gargle in decreasing COVID-19 transmission risk was explored by researchers in 2021.1 They looked at the evidence of the gargle's virus-killing aspects in relation to COVID-19. With that evidence, they endorsed the use of a diluted gargle (0.5% PVP-I) as a preventative measure when it comes to COVID-19.
Another study indicated that gargling with PVP-I resulted in salivary SARS-CoV-2 suppression for 60 minutes.2 However, a limitation of this study was that there was no control group for the study and that the findings might be more suited for short-term use by medical providers—namely, dentists or physicians who needed to perform an oral examination.
The efficacy of PVP-I in nasal form was also a point of exploration. Researchers discovered that there was a SARS-CoV-2 viral load reduction in all individuals from the 2021 study.3 The participants used placebo (saline), low-concentration PVP-I, and high-concentration PVP-I nasal sprays. However, there was not a significant difference in the viral reduction between the different groups.
Doctors don't recommend the general use of Betadine to prevent or treat COVID-19. Further, Betadine's manufacturer, Avrio Health, has also warned customers against using Betadine to prevent COVID-19. A statement has been included on Betadine's official website indicating that the sore throat gargle, as well as the first aid products, have not been approved to treat COVID-19.
Are There Any Dangers of Using Betadine as a Gargle or Nasal Spray?
Ingesting povidone-iodine can pose health risks. According to Dr. Adalja, povidone-iodine is commonly used for a gargle for sore throats, but accidentally ingesting it—whether you swallow it by mouth or put it up your nose and it drips down your throat—could cause gastrointestinal upset. If too much is swallowed, you'll need to seek medical attention or contact a Poison Control Center.
"High doses of povidone-iodine could also cause kidney problems," added Dr. Adalja, along with potentially interfering with thyroid function. Furthermore, according to Dr. Pierre, "it may tarnish the color of a person's mucus membranes and skin, and even cause pulmonary irritation and shortness of breath."
There is, of course, another danger too: It's that people are using remedies like povidone-iodine instead of the vaccine—which is proven to work.4 "It's odd because there's so much evidence for the vaccine, but people are turning to povidone-iodine…" said Dr. Adalja.
The best, safest evidence-based methods for preventing COVID-19 (and staving off severe disease and hospitalization) remain to be vaccination and masking.5 "People are looking for a quick and easy fix," said Dr. Pierre. "But the quick and easy preventative measure that's actually safe and proven is getting the vaccine and continuing to wear a mask."
Not enough time for all trials. The process was called operation warp speed under Trump. They cut a lot of corners and received immunity from lawsuits under EUA.
They did not cut corners when it comes to safety. That was evaluated the same as any drug. The difference was that certain portions of the testing process were overlapped. Regardless of the trials, we now have almost 2 years of field data and billions of shots given around the world. We have the data now.
