Merck said the shortage of its pediatric hepatitis B recombinant vaccine will continue through the rest of this year due to an ongoing manufacturing problem. GlaxoSmithKline will step in with its own pediatric vaccines to fulfill US demand, the CDC said.

CDC study finds low risk of Zika infection from semen
CDC researchers analyzed more than 2,000 semen and urine samples to test for the presence of the Zika virus after symptom onset, and found that the majority of semen contained the Zika genetic footprint for about 30 days, but the infectious virus was present in only 4%. The findings, reported in the New England Journal of Medicine, also showed that Zika infection through sexual transmission usually occurred within 20 days after symptom manifestation.

A study in Health Affairs found about 80% of uninsured patients willing to pay in full were able to obtain an appointment with a primary care clinician, while just 1 in 7 who needed to pay over time could secure a doctor's appointment in 2012-2013 and 2016. Federally qualified health centers were more likely to offer low-income discounts than private physician offices.
