Hello doctor,

My daughter is 1 year and three months. She was diagnosed by her pediatrician to have molluscum virus. Initially, there were 23 blisters (watery substance) started from 15th. The doctor advised applying Caladryl lotion on blisters and nothing else. No cream/powder, nothing. She was advised to take bath with drops of Dettol/Savlon in it. Right now, most blisters dried up and some more growing (current count is 8).

The issue is, she needs to take her vaccine (varicella vaccine) on the 7th. It seems like the doctor is keen to give it as well. There are some other vaccines as well to be given normally at 15 months.

I just need to double check, is it safe to go for the vaccine now? The doctor said molluscum will come and go on its own, but I am anxious to get my daughter out of it sooner. She has no itching and fever and is full of energy (touch wood). Please suggest three things:

  • Any alternative treatment for faster healing of this blister and to stop growth in any other places of the body?
  • Is vaccine mentioned above safe to be taken on 7th?
  • Is there any need to do any blood test to rule out any underlying disease?

I am really tensed. Please assist and suggest the best consultation for my daughter.

Please advise.



Welcome to

If it is molluscum, nothing to be worried about but if it is chicken pox, you need to start Acyclovir therapy for faster relief. Are the blisters causing some marks after they fade? Please discuss with your pediatrician about the probability of chicken pox. You can delay the scheduled vaccine for another week till she is free from this viral infection because the immune system is altered and the vaccine may flare up the infection. I suggest you hold the vaccine for a week or two.

If it is surely molluscum, the treatment what you are getting is appropriate as it goes on its own. No other tests or treatment required. Only thing is that you need to maintain good personal hygiene. No need to be tensed just relax, she will be alright.

Thank you.

Thank you doctor,

The doctor examined and confirmed the prescription as molluscum. How can I be double sure that it is molluscum? Any test needed?

As these bumps/blister goes away, I give you their life cycle below. Red small bump (microscopic) >> a bit enhanced in size (with water inside) >> then water matured to be white head on top of the bump >> after that it gets dried up >> dry skin peels out >> no scar/marks after they fade out.

What do you think? Is this chicken pox or molluscum?



Welcome back to

It seems to me like molluscum only, molluscum may initially appear to be chicken pox, but unlike the pox, these tiny blisters are not itchy or irritating. They do not leave any scar or mark on the skin whereas the rash from chickenpox may leave a mark or scar. So, it is molluscum. There is no test to differentiate both except history and clinical examination. Continue same medications.

I hope it helps.

Thank you.
