In reply to the discussion: CDC study shows three-fourths of people infected in Massachusetts covid-19 outbreak were vaccinated [View all]Ms. Toad
(34,130 posts)108. Again. I'm pretty sure transmission is possible in breakthrough cases
regardless of the variant. Too many people are prone to speaking in absolutes, or in exaggeration, without providing the data to back it up.
Heck - just the other day Biden said if you get the vaccine you won't get sick and you won't die.
It is hyprebole like this that increases the risk when vaccinated people treat it as gospel truth,
Delta certainly is much more contagious in vaccinated people than earlier variants - but I am prettysure it is a matter of degree, not binary.
Is a vaccinated person less likely to transmit the virus than one who is unvaccinated? Does viral load play a role?
Studies show that even though vaccinated people can get infected, their viral loads (the amount of virus present), as well as the duration of the viral shedding (how long viral particles are released during daily activities) are much lower compared to individuals without the vaccine. In that regard, the vaccination itself reduces the transmission rate.
Without vaccination, COVID-19 is transmitted largely by asymptomatic people. Its estimated that between 50% and 60% of transmission is by those who are infected but without symptoms, so they dont even know they are infected. Because they are unvaccinated, they might have a very high viral load, and that plays a big role in the course of the illness and likelihood of spreading the disease.
After vaccinations, such instances are dramatically reduced and the overall asymptomatic infection rate is much lower. Even if these individuals do become infected without symptoms, the viral load can be lower and the time period of shedding is narrower, so overall the chance of these people spreading the virus is much lower.

UABs Infectious Disease Expert Dr. Michael Saag says fully vaccinated people can become infected asymptotically or with minimal symptoms and still spread COVID-19 to others.
Saag says the situation with the New York Yankees is a good example of where a handful of players who got vaccinated still spread it to others.

Those percentages would be meaningful if all the vaccinated were infected with the Delta variant.

If it was neutralized, how would it reproduce in the host at the same rate as in the unvaccinated?
