The president’s empty advice that children should receive separate jabs against measles, mumps and rubella will only lead to less take-up by parents

Nobody wants to hurt a child. The howl of pain, the tears, the look of betrayed shock all make it very hard to deliver a cherished small person to the needle-wielding nurse. But that’s part of being a responsible parent. It becomes a lot tougher if mum or dad is being fed mixed and erroneous messages about the benefits and harms of vaccination.

Parents have to make a lot of decisions about what’s right for their child, from the school they should go to and the food they should eat to the hours they should spend on the phone or watching TV. In the US, Donald Trump wants them to add another: do they choose to give their children separate jabs against measles, mumps and rubella, involving six visits to the clinic, or should they opt for the combined MMR vaccine, which does the job in two? For decades, the vast majority of families have been taking the advice of doctors, accepting their assurance that the MMR vaccine is safe and very effective. But what are they to think when a US president announces that the triple jab could be “quite lethal” and signs an executive order advising states to offer separate vaccines?

By now we know that charity, generosity and compassion are virtues that the US president doesn’t seem to have even in trace amounts

Many years ago, in the crowded corridor of a Manhattan hotel, I was surprised to find myself standing face-to-face with Imelda Marcos, then the first lady of the Philippines. At that time, she was said to possess 3,000 pairs of shoes.

I desperately longed to ask the wife of the dictatorial president Ferdinand Marcos why anyone could need all those shoes. And more importantly, why would someone spend so much of her country’s wealth on stiletto heels when so many citizens were so desperately poor? But natural reticence, good manners or simply fear prevailed, and I walked away.
