"Many parents look to their physicians as the ultimate sources of information," said Dr. Walter Orenstein, associate director of Emory University's Vaccine Center, adding "now it's up to them."
The new analysis looked at dozens of medical studies completed since the 2011 report. It echoes some of those findings and included vaccines that report hadn't addressed.
The journal Pediatrics published the report online Tuesday. Among its conclusions:
--Newer evidence confirms a link between the measles-mumps-rubella vaccine and fever-triggered seizures. The seizures rarely cause long-term health problems, but can be frightening for parents.
--Apparently, flu shots can also spur fevers that can trigger seizures. The seizures seem to happen more often in children who get a vaccine against pneumococcal bacteria the same day.
--Newer vaccines against rotavirus, a severe diarrheal disease in children, slightly raise the risk of a rare bowel blockage.
The risks of serious side effects were deemed very low. For example, the rotavirus vaccines were linked to no more than five extra cases of the blockage for every 100,000 kids vaccinated.
