[ No, there is no evidence to support any benefits to “give the body a break” or “allow the immune system to settle down”. These are erroneous, non-medical assumptions that might seem common sense to people who aren’t doctors, but are based on fallacious information that has no basis in fact. ]
Have you ever had an allergy attack at the same time as being sick with the cold/flu?
It makes it a lot worse doesn’t it?
Also until you have had to suffer through an adverse vaccine reaction, you will never know, good luck on your next regualrly scheduled vaccination.
Hopefully you ask them to give you all the vaccines all at once. And hopefully you don’t get sick.
You should eat all of you meals at once too, it would save you bunch of time.
Maybe even hold in all your body waste until the end of the day, you can save a lot of time that way too.
Oh and please do all your breathing once a day too....
Do you eat multiple food groups at the same time? Do you eat your bread 5 hours after you meat in order to give your stomach "a break" or time to "settle down"? Do you space out vitamins?
See, this is the problem with making medical proclamations without any medical knowledge. You mistake "common sense" for evidence, and your "common sense" ends up being the wrong conclusion because it's based on erroneous assumptions, such as the immune system being "overloaded" by vaccines in the same way multiple illnesses will.
