As the opv indisputably proves, live virus vaccines can and do shed.

Fact. It's why we usually don't give the OPV in countries where the risk of polio is low, like the US, UK and Australia

Let's not get into that part lol, it really riles me up what gates is doing. So when we know that live vaccines can shed, and we still use them in the mmr although attenuated, why is there nothing done after to ensure no shedding when it is known to be possible. I see a flaw

Because, as I said, different vaccines are very different. The OPV sheds, and that's actually one of the things that makes it so effective. There's no evidence that the MMR sheds, because the attenuation is different btwn different diseases

There are a few reported cases of shedding specifically into breast milk, but it's an extremely low risk unless you're currently lactating. Since we mostly vaccinate kids, not usually a problem

It's also something that doctors usually mention when they're vaccinating breastfeeding mothers, because they might want to take that into account before being vaccinated

I'm liking this conversation and so far can agree. There are cases of mm shedding but it's rare. However varicella shedding is not so rare. Why do we even have chicken pox vax, it was a fun week

Mostly because it can be very disabling and occasionally deadly. Not every country vaccinates against varicella

But it's more dangerous to catch it as an adult. Since vaccines don't provide lifelong immunity (why there are boosters) it seems safer to catch it as a child and skip the vaccine

With 2 doses of the varicella vaccine, the lifelong risk of getting the disease drops to less than 1%, so not sure I see your argument

That's not possible to determine since it hasn't even been around 80 years...

We can estimate lifelong risk based on the number of people infected in a year in a population of vaccinated individuals, if you look at your individual chance of getting sick post vaccine it drops even further usually
