Yes. As early as the 1960s, research has shown that measles vaccines are highly effective in preventing disease and the complications caused by the disease after exposure. According to CDC data, receiving two doses of the MMR vaccine provides the highest level of protection, at 97% effectiveness. Even if only one dose is received, protection is still extremely high, at 93% effectiveness.
It only takes a few days for antibodies to develop in response to the MMR vaccine. Within two to three weeks, the immune system is fully primed after vaccination.
