vaccination

Four infants died after mmr shots.
Not maintaining the cold chain is said to be the probable cause.
I had once felt annoyed by someone who had commented about people not immunising their children and that being very unscientific...or words to that effect in one of the blogs I read.
This is what makes me thankful that I don't have small children to vaccinate. In fact, few years back, my daughter was admitted to a course in one of the institutes, where all the freshers had to have an anti-hepatitis shot. The vaccine was in a thermocol jar (the kind in which 2.5 l bottles of sulfuric acid are supplied) in the lecture hall at about 1 pm. The doctor was still administering the vaccine at 4 pm. I signed a statement saying that I had already given her an anti-hepatitis vaccine (true) and didn't want a booster dose. Three or four hours in a thermocol jar in July...what cold-chain are we talking about?
Weighing the risks, I feel, specially for boys, a bit of measles is better than the MMR shot. In any medical shop, vaccines are kept in a normal fridge. The temp. inside probably goes up to 25 or even 30 C after long power cuts that are regular features of life in our towns and cities.
Luckily for my peace of mind, when my kids were infants, this thought about break in cold chain did not occur to me. I only realised this when they were a little older and then I could plan their immunisation boosters before the summer power cuts. Except of course when my son got nipped by a dog. Now I will worry only when I have grandchildren.
