A new study published in JAMA Network Open found live vaccinations safe and effective for children who have received liver or kidney transplants, offering protection against life-threatening conditions. The study showed high antibody levels and minimal adverse events following vaccination.
Scientists have developed a trivalent vaccine candidate that provides broad and long-lasting protection against COVID-19 infection by delivering the vaccine via the nose. The vaccine triggers a strong neutralizing antibody response and protects mucosal areas, preventing disease symptoms.
A nationwide ecological study in Brazil found a significant decline in MMR vaccine coverage between 2006 and 2020, with approximately half of municipalities falling short of the 95% target. This decline may leave these areas vulnerable to future outbreaks.
A third of under-fives attending Paediatric Emergency Departments have unmet vaccination need, with tetanus and MMR vaccination coverage levels below target. Researchers call for catch-up campaigns to reach this vulnerable group.
Researchers create a modified live attenuated mumps virus for delivery, showing it induces stronger immune responses and provides superior protection against SARS-CoV-2. The new vaccine candidate uses a prefusion version of the spike protein and offers potential to enhance MMR childhood vaccine.
Researchers have published the first-ever look at a key stage in the life cycles of measles and Nipah viruses, revealing how future therapies might stop these viruses. The study identifies how paramyxoviruses utilize a host cell lipid for viral spread, providing a new target for developing inhibitors of the assembly process.
Researchers found an inverse correlation between mumps IgG titers and COVID-19 severity in vaccinated individuals. Those with higher mumps antibody levels had lower disease severity, suggesting the MMR vaccine may be protective against COVID-19.
A study by University of California - San Francisco researchers found that over a three-year period, more than a dozen ICE detention centers experienced large, repeated outbreaks of vaccine-preventable illnesses, including influenza, chickenpox, and mumps. The Centers reported nearly half of the infections occurred in two facilities.
Administering the MMR (measles, mumps, rubella) vaccine could serve as a preventive measure to dampen septic inflammation associated with COVID-19 infection. Vaccination has no contraindications and may be especially effective for healthcare workers who can easily be exposed to COVID-19.
Analyzing viral genomes from an outbreak can show how a virus is evolving and being transmitted. The study revealed new links between cases that first appeared unrelated and details about how the disease was spreading in Massachusetts and elsewhere in the US.
A recent study analyzing over 200 mumps virus genomes provides insights into the US outbreaks, revealing a dominant strain responsible for many cases. The research also demonstrates the value of high-quality genomic data in public health surveillance and suggests future efforts should incorporate whole genome sequencing.
Outbreaks of vaccine-preventable diseases like measles and whooping cough were associated with introduction of legislation changing vaccine exemption laws in states. The study found a correlation between health improvements and increased legislative activity related to vaccine policies.
A study by Emory Vaccine Center and CDC found immunity against mumps virus insufficient in a fraction of college-aged people who received MMR as children. The results highlight the need for better understanding of immune response to mumps and vaccines.
Recent outbreaks of measles and mumps have demonstrated the importance of integrated infection prevention response. Studies show that standard patient and visitor messaging, active surveillance, and timely initiation of precautions can effectively control outbreaks. Vaccination rates were also critical in stemming the outbreak, with a ...
A recent resurgence in mumps cases in the US is attributed to declining immune protection from the mumps vaccine. Researchers propose a booster dose at age 18 as a potential solution to maintain population immunity and control outbreaks.
A new analysis from Harvard T.H. Chan School of Public Health suggests that waning immunity is a major factor in the recent mumps resurgence among young adults in the US. The study found that vaccine-derived immune protection against mumps persists for approximately 27 years after the last dose.
A study found that youth infected with HIV in utero may not have adequate immunity to measles, mumps, and rubella, even if vaccinated. Those who started antiretroviral therapy early were more likely to have protective antibodies against these diseases.
Researchers have discovered a subset of plasma cells in the bone marrow that serve as an immune archive, preserving a catalog of how the body responded to measles and mumps viruses in childhood. These long-lived cells can provide valuable insights for vaccine designers aiming to create long-lasting antibodies.
