Let them play (bundled up, of course) in the snow! Flu vaccines are about 65% effective, but only generally work for one season.

Mostly, the immune system stops the virus taking hold, but as the temperature drops, so does the body’s ability to fight off the intruder. The common cold viruses can survive better when humidity is low 3,4. A study published in The New England Journal of Medicine in the late 1970s famously debunked the belief that the common cold is linked to cold exposure, but British cold researchers have maintained that there is a cold–to–common cold connection.
