Pharmaceutical company GlaxoSmithKline says higher sales of vaccines and consumer healthcare products pushed up its earnings from core business by 19 percent in the first quarter.
Core operating profit, which excludes taxes, one-time items and restructuring costs, rose to 1.56 billion pounds ($2.28 billion) from 1.31 billion pounds in the same quarter a year earlier.
Sales of vaccines rose 23 percent to 882 million pounds and sales of consumer healthcare products increased 26 percent to 1.76 billion pounds. Pharmaceutical sales fell 1 percent to 3.59 billion pounds, hurt by competition for the Advair asthma treatment.

Chief Executive Andrew Witty says the results demonstrate the momentum across the group "driven by growth in sales of our new products, effective cost control and execution of our restructuring and integration plans."
