So that’s what it is!

Netflix has that warning on every episode, so ¯\_(ツ)_/¯

It’s not even that! The electrons don’t even move particularly much. The energy is moved by the E/M field created around the circuit, which is even more wild and mind bending.

It does depend on the disease and the vaccine.

Usually, yes, vaccinated people can still carry and transmit the disease. However, they’re much more likely to have less severe or even no symptoms, and for many diseases they’re also much less likely to transmit than an unvaccinated person.

The real answer to your question is: the more people that are vaccinated, the safer everyone is. It is the height of self-centered self-importance for anti-vaxers to consider their right to avoid minor side effects as more important than the health and safety - potentially even the life - of the immunocompromised people in their community.

That’s measuring airflow required, which is not equivalent to energy required.

You can very safely remove the “probably” from your first sentence.
