SINOVAC Donates 100,000 Doses of Hepatitis A Vaccines to Pakistan

November 9, 2022, Islamabad -- Sinovac Biotech Ltd. ("SINOVAC" or the "Company") (NASDAQ: SVA), a leading provider of biopharmaceutical products in China, announced that the Company donated 100,000 doses of the hepatitis A vaccine, Healive® to Pakistan, to help improve the local communities' health conditions during the country's post-disaster reconstruction.

This year, Pakistan suffered from the worst floods in the country's history, posing severe challenges to local people's lives. Residents at relief camps are vulnerable to disease transmission, and the outbreak of hepatitis A virus is highly likely, according to the Pakistani Federal Health Minister, Mr. Abdul Qadir Patel.

"Providing assistance to the flood-affected populations of Pakistan is the government's top priority. We are really grateful for the donation of 100,000 doses of the hepatitis A vaccine from SINOVAC for children and adults," said the minister during the handing over ceremony held in Islamabad on Wednesday.

As one of the flagship products of SINOVAC, Healive® is the first and only hepatitis A vaccine from China, which passed the assessment under the WHO Prequalification Procedure. It offers sustained protection for over 30 years after full-course immunization. Including in Pakistan, Healive® has been registered in 21 countries and organizations around the world, and authorized to be administered in 33 countries and areas, so far.

Dr. Muhammad Ahmed Kazi, the Director General of Pakistan Federal Directorate of Immunization, said, "I thank the whole SINOVAC team for the assistance provided and assure that it will be used in the best possible manner to benefit the children and adult populations of Pakistan. We are looking forward to a continued partnership."

Gao Qiang, Chief Operating Officer of SINOVAC, said, "Pakistan and China are close friends and all-weather strategic partners. As a leading provider of biopharmaceutical products in China, SINOVAC has established a good friendship and partnership with Pakistan for years. The donation shows not only our care to the country, but also demonstrates the social responsibilities we are taking on."

Prior to the announced donation of the hepatitis A vaccine, SINOVAC has provided approximately 100 million doses of CoronaVac®, its COVID-19 vaccine, to Pakistan since the outbreak of COVID-19.
