During a rabies outbreak, a vaccine manufacturer stops selling its product without informing the FDA. Which law is violated?

• A. RA 7394
• B. RA 11223
• C. RA 11210
• D. RA 9502

Answer: (D)

During a public health emergency, regulators expect manufacturers to maintain access to essential vaccines and to keep authorities informed about any changes that could affect safety or availability. Stopping sales of a vaccine without notifying the FDA breaks the duty of regulatory transparency and disrupts oversight of product distribution during a rabies outbreak. Republic Act 9502 covers the regulation of pharmaceutical products and sets responsibilities for manufacturers to report changes in availability or distribution to the FDA. That obligation directly addresses ensuring continuous, safe access to vaccines for the population, which is why this option is the best fit for the scenario.

The other laws address broader consumer rights (without tying specifically to regulatory reporting on drug supply) or health coverage and system-wide health provisions, but they do not establish the exact regulatory duty to inform the FDA about halting sales of a vaccine in the middle of an outbreak.
