New study highlights potential role of diet – MedNewsToday

Should we vaccinate children against SARS-CoV-2? – The Lancet

Following sharing with regulatory bodies of phase 3 trial data showing that Pfizer-BioNTech’s mRNA BNT162b2 vaccine was efficacious, immunogenic, and safe in children aged 12–15 years, several countries have authorised the use of the vaccine in this age group. Reactions to this news have been mixed. Although it is considered likely that children will have to be vaccinated against SARS-CoV-2 eventually, there is the question of whether now is the right time. Many public health figures think not, considering that children typically experience only mild illness and many of the world’s low-income and middle-income countries (LMICs) are reporting vaccine shortages. Countries with enough doses to cover their children might consider donating excess doses to countries that do not have enough vaccine to immunise the extremely vulnerable, older people, and front-line health workers.

FDA advisers debate standards on a coronavirus vaccine for young children – Washington Post

With coronavirus vaccines available to adolescents and adults, regulators are now turning their attention to younger children and the level of proof needed before authorizing shots for children as young as 6 months.
