The Covid vaccines, a triumph of science and public health, are estimated to have prevented millions of hospitalizations and deaths. Yet even the best vaccines produce rare but serious side effects.
An interesting recent study on COVID....
Higher CO2 Levels Have a Concerning Effect on Viruses Floating Through The Air

... Keeping CO2 levels low reduces infectious airborne viral loads, new research suggests. While the study focused on the pathogen behind COVID-19, it has clear implications for reducing the risk of transmitting viruses in spaces where ventilation is limited.
"Opening a window may be more powerful than originally thought," says University of Bristol chemist Allen Haddrell, "especially in crowded and poorly ventilated rooms, as fresh air will have a lower concentration of CO2, causing the virus to become inactivated much faster."
By measuring SARS-CoV-2 capacity to remain infectious while aerosolized in droplets under different environmental conditions, Haddrell and colleagues discovered the virus's stability is directly impacted by CO2 levels in the air. They used a new technique called Controlled Electrodynamic Levitation and Extraction of Bioaerosol onto a Substrate (CELEBS), which measures the impact of temperature, relative humidity, and different gas concentrations on suspended virus particles.
Atmospheric CO2 concentrations are currently around 400 parts per million (ppm). Crowd enough people in a closed room, however, concentrations can soar to around 3,000 ppm. The team found the number of viral particles that can remain infectious under these elevated concentrations can be 10 times higher than what would be found in outdoor air.
"The high pH of exhaled droplets containing the SARS-CoV-2 virus is likely a major driver of the loss of infectiousness," explains Haddrell. "CO2 behaves as an acid when it interacts with droplets. This causes the pH of the droplets to become less alkaline, resulting in the virus within them being inactivated at a slower rate." ...
@#30 ... Also, let's not forget that the entire executive and legislative branches were exempt from mandatory vaccination. ...
Congress often exempts itself from the laws it passes, and has done so for years (decades?).

Again, what's your current alias' point? Aside from deflection.
Right wingers don't get that.

It's not that they don't understand, it's that they don't care. Right wingers don't care about anyone other than themselves. Period.
There are countless articles from nurses and doctors that document how during the pandemic these vaccine deniers begged and pleaded for the vaccine AFTER it was too late and they were being placed on a ventilator (and most likely dying from COVID).
"I'm admitting young, healthy people to the hospital with very serious Covid infections," wrote Cobia in a Facebook post on Sunday.
"One of the last things they do before they're intubated is beg me for the vaccine. I hold their hand and tell them that I'm sorry, but it's too late," she added, referring to patients who have to be put on a ventilator.
Alabama public health officials recently reported 96% of Alabamians who have died of Covid since April were not fully vaccinated.

Now you might say, "Well, it's THEIR choice" and you're not wrong. But every hospital bed occupied by someone dying of COVID is not there for other patients. Doctors, nurses and supplies are used. Hospitals incur costs that might not be paid if the patient doesn't have insurance. That effects us all.
To see into a persons moral character look at how they react to the smallest inconvenience to save the life of a stranger. The pandemic exposed that in all of them.
