#4: How Does the Flu Vaccine Effect Preterm Vs. Full-Term Infants?
Researchers led by Carl D’Angelo, MD, a physician in the Department of Pediatrics at the University of Rochester Medical Center in Rochester, New York, compared flu vaccine response in preterm versus full-term infants.
A similar study conducted in 2011 investigated the efficacy of administering the measles vaccine in preterm infants, due to the lower levels of antimeasles antibodies found in this population in comparison to their full-term counterparts. This study found that preterm infants should be vaccinated for measles at 5 months, rather than 9 months.
More recently, the researchers led by Dr. D’Angelo set out to examine the “relationships among the frequencies of influenza-specific antibody secreting cells (ASC) and ASC subsets (including LLPC) and antibody responses to influenza vaccines,” among these populations. Infants included in the study received their first flu shot (2 doses of inactivated, trivalent IV or quadrivalent IV during the 2012-2013 and 2013-2014 flu seasons) between 7 and 17 months. The first dose was administered on day 0 of the study, while the second was administered on day 28.

#3: Mumps Outbreak at Penn State Infects More than 80 Individuals
An outbreak that started in January at Penn State has not been declared over. According to local news sources, the outbreak has infected almost 90 individuals on campus.
Penn State immunization recommendations require most students to receive 2 doses of the measles-mumps-rubella (MMR) vaccine, unless they are exchange students, non-degree-seeking students, World Campus students, or are immune to infection, among others. Nevertheless, “most of the confirmed mumps cases are in students who received the Centers for Disease Control and Prevention-recomended two doses of MMR vaccine,” according to University Health Services (UHS).
According to Shelley Haffner, infectious disease manager at UHS, “While many students who contracted mumps earlier this semester are no longer infectious, we are still continuing to see several new cases each week on campus… It is important that everyone take steps not only to protect themselves from possible exposure, but also to prevent exposing others should they develop symptoms.”
Penn State has already taken the necessary measures to prevent further spread of the outbreak, including barring some students from campus, and isolating others.
