LONDON (AP) — With swine flu now an official pandemic, the race is on among drugmakers to produce a vaccine.
GlaxoSmithKline said Thursday after the World Health Organization declared a global flu epidemic that it would be ready within weeks to begin large-scale vaccine production. Sanofi-Aventis also said it had started working on its own version. On Friday, Swiss pharma giant Novartis announced it had created an experimental vaccine that has been tested in people. Novartis' vaccine was made via a cell-based technology that may prove faster than the traditional way of making vaccines, which relies on chicken eggs.
