Midday Roundup: Going to Disneyland? Make sure you've had your shots

Sick days. Health officials in California this week warned people who have not been vaccinated for measles to stay away from Disneyland in Anaheim, the epicenter of an outbreak that has infected 70 people. The outbreak began in December and has affected more than just the theme park. A high school in Orange County asked 24 unvaccinated students to stay home for three weeks after a student with measles came to school. A movement against childhood vaccinations appears to be playing a role in the outbreak and public health officials’ response to it. The families of about 3 percent of incoming kindergartners in Orange County have registered “personal-belief exemptions” to vaccinations, according to the Los Angeles Times. In some California counties, that number is in the double digits.

Real-world trials. Trial doses of two new Ebola virus vaccines are expected to arrive in West Africa today. Researchers plan to conduct a major test of the drugs in Liberia, where the Ebola epidemic is waning but not over yet. Up to 27,000 people could participate in the study, which will compare the effectiveness of the drugs to each other and a placebo. The U.S. National Institutes of Health developed the first vaccine, and Canadian health officials developed the other, with both being manufactured by U.S. companies. The World Health Organization says the Ebola epidemic in West Africa has infected more than 21,000 people and claimed more than 8,600 lives.

Pending decision. The attorney general of Nebraska asked a federal court to pause a lawsuit about same-sex marriage there pending the U.S. Supreme Court’s expected ruling on the issue this summer. The high court announced this month it plans to consider whether the 14th Amendment of the Constitution requires states to issue marriage licenses to same-sex couples as a matter of equality. Litigation on same-sex marriage is underway in a handful of states and in the 5th U.S. Circuit Court of Appeals, which includes Texas, Louisiana, and Mississippi. Most states have already seen federal courts strike down existing laws defining marriage as between one man and one woman. The American Civil Liberties Union is fighting the request for delay in Nebraska, noting that couples are ready to get their marriage licenses now.

Illegal affair. The Navy has removed its commanding officer at Guantanamo Bay, Capt. John R. Nettleton, after linking him to an ongoing death investigation. The Coast Guard found the body of Christopher Tur, a civilian who worked on the base, in the waters of Guantanamo Bay on Jan. 11. While investigating his death, officers uncovered accusations that Nettleton was having an affair with Tur’s wife, which is a violation of military law. Nettleton was reassigned to a staff position in Jacksonville, Fla. In his role at Guantanamo Bay, Nettleton commanded the naval base but did not have a role in the famous detention center that houses suspected al-Qaeda operatives.
