Using targeted antiviral prophylaxis (TAP) on close contacts of suspected flu cases can effectively contain an epidemic, with only 2% of the population becoming ill and a death rate of 0.04 per 1,000 people. TAP is nearly as effective as vaccinating 80% of the entire population, especially when used for eight weeks.
The study found that inactivated influenza virus vaccines are effective in protecting children against the flu, reducing hospitalization rates comparable to those of elderly people. Vaccinating children can also protect adults from getting infected and save money on treatment costs.

This year's flu season is severe due to a mutated virus that has changed slightly since last year's vaccine was designed. Young children are at higher risk of getting seriously ill as they haven't encountered the virus before and lack immunity. Experts recommend vaccinating all children aged 6 months to 23 months to prevent complications.
