Influenza is a hot topic in Winter. T he United Sstates Centersfor Disease and Prevention (CDC) recommends that people older than 6 months should receive flu shots.
Flu shots often have very low efficacy and many people who have received the flu vaccine still contractthe viral infection. And many people including doctors and nurses do not want flu vaccine because flu isoften times not a severe medical condition for healthy people and they fear the vaccine may cause somepotential side effects.
