TRICK QUESTION...There is NO DIFFERENCE between unvaccinated people vs. people vaccinated against COVID-19 when it comes to catching and spreading COVID-19
We can ALL spread COVID-19 if infected.
What about viral loads between the 2 groups?
Infection with the SARS-CoV-2 Delta Variant is Associated with Higher Infectious Virus Loads Compared to the Alpha Variant in both Unvaccinated and Vaccinated Individuals (PRE-PRINT)
"The Delta variant displaced the Alpha variant to constitute 88.2% of the circulating lineages in the National Capital Region by July, 2021. The Delta variant associated with increased breakthrough infections in fully vaccinated individuals that were mostly symptomatic when compared to the Alpha breakthrough infections, though it is important to note there was a significantly longer period of time between vaccination and infection with Delta infections.
The recovery of infectious virus on cell culture was significantly higher with the Delta variant compared to Alpha in both vaccinated and unvaccinated groups.
The impact of vaccination on reducing the recovery of infectious virus from clinical samples was only observed with Alpha variant infections but was strongly associated with low localized SARS-CoV-2 IgG for both variants. A comparison of Ct values showed a significant decrease in the Delta compared to Alpha with no significant differences between unvaccinated and vaccinated groups"

No Significant Difference in Viral Load Between Vaccinated and Unvaccinated, Asymptomatic and Symptomatic Groups Infected with SARS-CoV-2 Delta Variant
"We found no significant difference in cycle threshold values between vaccinated and unvaccinated, asymptomatic and symptomatic groups infected with SARS-CoV-2 Delta. Given the substantial proportion of asymptomatic vaccine breakthrough cases with high viral levels, interventions, including masking and testing, should be considered for all in settings with elevated COVID-19 transmission."
Wide variations in viral load
"When they analyzed the data, the researchers found wide variations in viral load within both vaccinated and unvaccinated groups, but not between them. There was no significant difference in viral load between vaccinated and unvaccinated, or between asymptomatic and symptomatic groups."

When are viral load and viral shedding the highest?
The temporal patterns of viral shedding vary among different infections. The consensus for COVID-19 is that the viral load and viral shedding are highest on early days of the infection, peaking on or before symptoms onset. One study estimated that 44% of transmission could occur before the first symptoms show up. Another study monitored viral shedding over the course of disease progression and found that viral shedding drops 5 days after symptoms onset and stops after day 10.
COVID-19’s temporal shedding profile is in stark contrast to SARS. Viral shedding for COVID-19 peaks much earlier, and at much higher levels. Unfortunately, heaving shedding early in infection makes it harder to contain the virus, which likely contribute to COVID-19’s rapid spread."
So, if we can all catch COVID-19, we can ALL transmit COVID-19 to both vaccinated and unvaccinated people, and when infected, both vaccinated ans unvaccinated have the same viral loads...
WHY ARE THE UNVACCINATED BEING EXCLUDED FROM SOCIETY WITHIN AUSTRALIA?
