how does mmr vaccine works

Answer 1

The MMR (Measles, Mumps, Rubella) vaccine works by triggering the immune system to produce antibodies against the viruses that cause these diseases. The vaccine contains weakened or dead versions of the viruses that cannot cause the diseases themselves but are still recognized by the immune system. Upon receiving the vaccine, the body will recognize these viruses and produce antibodies to attack them, effectively building immunity to these diseases. This immunization gives the body the ability to fight off these viruses in the event of future exposure, decreasing the likelihood of contracting the diseases.
