Q: Please tell me about the new M.M.R vaccine, which is being advertised on news channels.

A:The new MMR vaccine is made from a different strain of the virus. This vaccine has been shown to have lower incidence of neurological side effects, in comparison to the earlier vaccine. However, neurological side effects are extremely rare even with the older vaccine and the newer vaccine is much more costly. If you cannot afford the cost of the newer vaccine, do not lose any sleep and get the child immunised with the older vaccine type.
