THURSDAY, June 2, 2022 (HealthDay News) -- Children who have had COVID-19 aren't protected against the Omicron variant, but vaccination does cut their chances of infection, a new study shows. "I hear parents say, 'Oh, my kid had COVID last year,'" said senior study co-author Dr. Adrienne Randolph, from Boston Children's Hospital. "But we found that antibodies produced by prior infections in children don't neutralize Omicron, meaning that unvaccinated children remain susceptible to Omicron," she added in a hospital news release.For the study, Randolph and her colleagues analyzed blood samples from 62 children and teens hospitalized with severe COVID-19, 65 children and teens hospitalized with COVID-related multisystem inflammatory syndrome in children (MIS-C), and 50 youngsters who had...

WEDNESDAY, June 1, 2022 (HealthDay News) -- Breastfeeding may literally help your baby breathe more easily, according to new research that found the longer an infant is fed mother's milk exclusively, the lower the baby's chances of developing asthma."Breastfeeding for at least six months was the most protective but, importantly, it is likely that shorter amounts also provide some protection against asthma," said study author Dr. Keadrea Wilson, an assistant professor of neonatology at the University of Tennessee Health Science Center in Memphis.The American Academy of Pediatrics recommends exclusive breastfeeding for about six months, followed by continued breastfeeding as foods are introduced for one year or longer, due to the long list of potential health benefits associated with...

WEDNESDAY, June 1, 2022 (HealthDay News) -- Not every woman is ready to become a mom in her late teens, 20s or even by her mid-30s, but a natural decline in fertility can make it more difficult to have a baby at age 40 and beyond.Now, a new study shows that freezing eggs while younger is a largely successful option for many women who are fertile in their younger years but want to delay pregnancy for a while.The researchers looked at success rates of using a woman's own frozen eggs over 15 years. They found that about 70% of women who had eggs frozen when they were younger than 38, and thawed at least 20 of those eggs, later had a baby.Not only that, but egg freezing and then thawing at a later date provided a higher pregnancy success rate than using fresh embryos with assisted...
