Its commitment to innovation and willingness to self-fund large programs created major vaccines with drug-like potential, and little competition, itself a hallmark of the business to which Merck, and few other companies, has remained loyal. But the costs and risks of the program raise questions as to its long-term viability at a time when Merck's profits are under increasing pressure.
