Practice tonight?

Are you a practicing physician in pediatrics, family medicine, internal medicine or immunology? How old are you? Your explanation is a bit suspect. Either you forgot the details of the material (pretty normal for docs who don't practice primary care and don't care to keep up with material that affects their and their family 's health) or you misunderstood something in microbiology and pharmacology classes. Also 99% of physicians I know would know better than to use anecdotal evidence of getting sick only twice with the flu after the only two times they got the vaccine. Were those years the vaccine was less effective? Or maybe the years the flu was more wide spread?

The flu virus mutates every single year (often multiple times per year) which is why there is a new vaccine annually. The immune system cannot be built up against a virus to which it has no exposure. Not getting the flu vaccine does not give you a better immune system. There is no relationship between those two independent acts. The virus does not mutate because of the vaccine either. Vaccines are there to prevent infection, not treat the infection. The viruses can mutate upon exposure to antivirals like Tamiflu. Eventually we may see some of that.

Now...you ARE correct about antibacterial soap. Bacteria DO mutate to form resistance against the soap just as they do against antibiotics. That is due to the methods by which antibacterial soap and antibiotics try to kill the bacteria.

Now I hope everyone enjoyed the microbiology lesson!😜

As an aside the cold temperatures for smaller children who are not well dressed can lead to frostnip and frostbite particularly when combined with being wet. Personally I was surprised that the clubs canceled at turf locations but there may have still been wet areas that they were afraid would ice over and be dangerous for slipping and falling. I know that on the grassy areas near me there was still standing water that turned to ice.
