MMR and V (two visit), MMR+V (one visit) or MMRV (one visit)

My baby #3 turns 1 today. 

This means that he will be due for his Measles, Mumps and Rubella (MMR) vaccination in accordance to the Singapore National Child Immunisation Program. We can opt for this MMR vaccine or for added convenience MMR+V (MMR and Varicella in two separate injections) or MMRV (MMR and Varicella in one injection). Varicella is also commonly known as chicken pox.

We had made an appointment with the government polyclinic for the MMR vaccination not only because this is the free (fully subsidised) option but this option poses the least risk for fever and fever induced seizures (fits). We will do the Varicella vaccination 42 days later.
