Study: Flublok is more effective than traditional flu shot

Protein Sciences released data showing that Flublok Quadrivalent--its follow-up to the FDA-approved trivalent Flublok--outperformed the traditional egg-based quadrivalent vaccine. The study involved approximately 9,000 subjects aged 50 or older, half of whom were given Flublok Quadrivalent. The other have received an egg-based vaccine. The results show 31% more people were protected by Flublok than by the traditional vaccine. Release
