No: A child should get a measles vaccine (MMR = measles, mumps, rubella vaccine) once after his first birthday, and a second time after his 4th birthday or at age 4-5 years. Some children get an extra dose of measles vaccine BEFORE their first birthdays, but that extra dose is for extra protection and does not count towards the future 2 doses. Thus, some kids have 3 total doses.

It will just help to boost his immunity - nothing bad about that.

No problem: This is often recommended at 6 mo for travel in countries with measles outbreaks. It would not count as the first dose in the normal series, needing to be given on or after age 1 and again after 4-5. The only "side effect" of any note is it hurts to get a shot. The other stuff promoted by vaccine haters has been debunked.
