The International Monetary Fund last month forecast that China's economy, the second-largest in the world, would decelerate from 4.8% last year, to 4.6% in 2025 and 4.5% in 2026. A collapse in the Chinese housing market has undermined consumer confidence.
Overall sales of Gardasil fell 17% to $1.55 billion in the final quarter of last year, mainly due to the lower demand in China.
Gardasil vaccine protects against cancer-causing human papilloma virus or HPV infections. The pause announcement comes a month after Merck received approval in China for use of the vaccine in males.
“We believe China still represents a significant, long-term opportunity for Gardasil, given the large number of females and now males with our recent approval that are not yet immunized,” Davis said.
