Vaccine adverse events rarely recur when children receive the same vaccine again, or one with similar ingredients, according to researchers with the Canadian Immunization Research Network. Investigators analyzed 29 studies published between 1982 and 2016 on recurrent vaccine side effects in children. Severe reactions included seizures and a potentially dangerous allergic response called anaphylaxis. They found that just 5 percent of children who reported adverse events following immunization “had another allergic response after being re-vaccinated.” Fevers, a common side effect, recur more often but were reportedly “milder and short-lived the second time around.” The findings were published online Aug. 28 in the journal Pediatrics.
A new study from the University of Utah found that “religious young women are less knowledgeable about a vaccine that guards against several different types of cancer.” Researchers recruited female patients between the ages of 18-26 at the University of Utah Community Clinic. After analyzing over 300 responses, they found that “about 97 percent of non-religious women had heard of HPV, compared to about 90 percent of religious women. Similarly, religious women were less likely than their non-religious peers to have heard of the vaccine (60 percent), to know how HPV is spread and to have their healthcare provider recommend the shots.” Young women who practice religion were also “about half as likely to have received at least one dose.” Researchers were surprised by the gaps in education and vaccine uptake between groups, specifically considering that HPV is the most common sexually transmitted infection: “One thing you might expect is that they might be less likely to receive the vaccine or they may perceive themselves as having less risk,” said senior author Deanna Kepka, of the University of Utah’s Huntsman Cancer Institute and College of Nursing in Salt Lake City. ‘I wouldn’t expect them to be less informed about the vaccine.’”

Mothers who received seasonal TIV during pregnancy were significantly less likely to experience stillbirth compared with unvaccinated mothers. These results support the safety of seasonal influenza immunization during pregnancy and suggest a protective effect.

Pregnant women are at higher risk for serious illness and complications, including death, from influenza. For expectant mothers hospitalized with flu, early treatment with the influenza antiviral drug oseltamivir may shorten their time in the hospital, especially in severe cases, suggests a study published in The Journal of Infectious Diseases. The findings also underscore the importance of flu vaccination for this risk group.
