The average healthy person suffers no adverse health effects from eating an egg a day. People with diabetes or who already have heart disease probably should eat no more than three egg yolks per week.
The nasal flu vaccine is more effective for young children, and the high-dose flu shot may be better for older adults, two new reports say. The advice on flu vaccines for children comes from a committee that advises the U.S. government. The Flu-Mist vaccine is preferred for healthy children ages 2 through 8, the committee said. This vaccine is given as a nasal mist. It contains live flu virus that has been altered so it cannot cause flu. Children can also receive standard flu shots. The new information about the high-dose vaccine comes from a study published August 15. Nearly 32,000 adults, ages 65 or older, were randomly divided into 2 groups. One group received standard flu shots. The other group got high-dose flu shots. Those who got the high-dose shots were 24% less likely to develop flu than those who got the standard shots.
