Is it safe to take bcg, polio, measles, rubella, meningitis (quadrivalent) and hepatitis b vaccines together on the same day?

Contraversial: Not clear as to why some children and even adults get a variety of reactions following vaccines. Obviously, there is an increased incidence of autoimmune problems worldwide, but this may or may not reflect increased vaccine use. No evidence that taking all together vrs separately will make any substantial ultimate difference, but personally, I am NOT clear regarding ultimate safety.
