Pfizer, US Army nab a new approval for a decades-old vaccine

It won’t make Pfizer even a minuscule fraction of what its other new vaccines have and will earn, but the New York drugmaker has gotten yet another inoculation approved by the FDA.

Pfizer announced Monday that US regulators have OK’d Ticovac, the company’s vaccine for tick-borne encephalitis, a virus that infects the brain and nervous system and can sometimes cause long-term cognitive, skeletal or muscular effects.
