Question 1

What is the MMR vaccine?

Accepted Answer

It's a combination vaccine that protects against three viral diseases: measles, mumps, and rubella.

Question 2

Who should get the MMR vaccine?

Accepted Answer

Children routinely receive it (first dose at ~12–15 months, second dose ~4–6 years). Teens and adults without documented immunity should receive two doses, especially if they are at risk (e.g., healthcare workers, travellers).

Question 3

How safe is the MMR vaccine?

Accepted Answer

It has one of the strongest safety records among vaccines. Side effects are mild and transient; serious reactions are infrequent.

Question 4

How many doses are required?

Accepted Answer

Two doses are standard. The second dose provides additional protection and reduces the likelihood of failure after the first dose.

Question 5

Why is the MMR vaccine important for public health?

Accepted Answer

It prevents outbreaks, reduces disease burden, protects vulnerable populations, and helps maintain immunity (herd protection).

Question 6

Does the MMR vaccine cause long-term side effects?

Accepted Answer

There is no credible evidence linking the MMR vaccine to long-term adverse effects. Extensive studies confirm it is very safe.

Question 7

What strains or types does this vaccine protect against?

Accepted Answer

The vaccine contains live attenuated strains of measles virus, mumps virus, and rubella virus, the very viruses that commonly cause these diseases globally.
