Health experts are urging individuals vaccinated against rabies since November 2023 to consult doctors due to a suspected counterfeit vaccine circulating in India. Australia's ATAGI flagged a fake rabies vaccine differing in formulation and packaging, warning it may not provide adequate protection. Doctors advise those unsure about their vaccine's authenticity or batch number to seek medical assessment for potential revaccination, emphasizing that while there's no need to panic, rabies is fatal once symptoms appear.
