It is that time of year again. I gave my first flu shot of the season this afternoon. The flu vaccine is your best defense in preventing the flu. The vaccine can't prevent all cases of the flu since the viruses are always changing. Each year the flu vaccine is set to help against 3 or 4 strains of the virus. It also takes about 2 weeks after receiving the vaccine for protection to develop.
