New confirmed cases raise DRC Ebola outbreak total to 3,099
According to the World Health Organization's (WHO's) online Ebola dashboard, officials in the Democratic Republic of the Congo (DRC) confirmed 8 new cases of the disease today, raising the outbreak's overall total to 3,099. Health officials are also investigating 409 suspected cases.
Three new deaths were also recorded, which moves the fatality count to 2,074, the WHO said.
In an update today from the DRC's multisector Ebola response committee (CMRE) on seven cases identified yesterday, the CMRE said Beni and Mambasa had two cases each, while Kayna, Mabalako, and Mandima each recorded one case.
Global Vaccination Summit launches in Brussels
In an effort to galvanize global efforts to stop the spread of vaccine-preventable diseases and curb vaccine misinformation, the European Commission (EC) and the World Health Organization (WHO) today hosted the world's first Global Vaccination Summit in Brussels.
In a joint statement, Jean-Claude Juncker, EC president, said it's inexcusable that in a developed world, children still die of diseases that should have been eradicated long ago. "Worse, we have the solution in our hands but it is not being put to full use. Vaccination already prevents 2 to 3 million deaths a year and could prevent a further 1.5 million if global vaccination coverage improved," he said. "Today's summit is an opportunity to address this gap."
Tedros Adhanom Ghebreyesus, PhD, the WHO's director-general, said the world is at a critical turning point, with measles resurging and 1 in 10 children missing out on key childhood vaccines. "We can and must get back on track. We will only do this by ensuring everyone can benefit from the power of vaccines – and if governments and partners invest in immunization as a right for all, and a social good," he said. "Now is the time to step up efforts to support vaccination as a core part of health for all."
Over the past 3 years, seven countries—including four in Europe—have lost their measles elimination status, with new outbreaks resulting from gaps in vaccine coverage, including teens and adults who were never fully vaccinated. The summit's goal is to address vaccination barriers such as rights, regulations, and accessibility, as well as access to vaccination services. Other topics include social and cultural norms, individual motivation, attitudes, and knowledge.
The EC and the WHO also urged strong support for GAVI, the Vaccine Alliance, which plays a critical role in making vaccines available to lower income countries.

Moderna reports promising interim trial results for CMV vaccine
Moderna, Inc., a biotechnology company based in Cambridge, Mass., today announced promising interim findings from a phase 1 trial of its messenger RNA (mRNA) cytomegalovirus (CMV) vaccine (mRNA-1647).
Sallie Permar, MD, PhD, with Duke Medical School, said in a Moderna press release that CMV is the leading infectious disease cause of birth defects, and there is a need for a vaccine that can block transmission from mother to fetus. She said the interim data are exciting, because they show that the vaccine can induce immune response in seronegative individuals that is greater than what is seen in natural CMV infections. That finding is important, because natural immunity doesn't completely protect against congenital CMV transmission.
The phase 1 study enrolled 169 healthy adult volunteers, including those who have and haven't been exposed to CMV. Participants were randomized to receive placebo or one of four different vaccine doses given three times at 0, 2, and 6 months. The interim findings are based on the first three dose levels at 3 months, 1 month after the second dose, and before the third dose.
The safety analysis found that the vaccine was generally well tolerated with injection site pain the most common local adverse event.
Based on the interim phase 1 data, Moderna said it will advance mRNA-1647 to a phase 2 dose-confirming trial that will test the intended phase 3 study formulation.
CMV, a member of the herpesvirus family, infects about 25,000 newborns in the United States every year, and birth defects—many of them neurodevelopmental—occur in about 20% of them.
