DUBAI, United Arab Emirates (AP) — Bahrain has begun offering a booster shot of the Pfizer-BioNTech coronavirus vaccine for some people six months after they received two shots of China’s Sinopharm vaccine.
The mixing of vaccines comes as the Mideast island nation struggles through its worst wave of the virus despite being one of the top countries in the world in per-capita inoculations.
The government’s BeAware mobile phone app allows those living in Bahrain to register for booster shots of either the Pfizer or the Sinopharm jabs. However, the government now recommends that people over 50, the obese and people with weakened immune systems receive the Pfizer shot regardless of if they first received Sinopharm.
Bahraini government and health officials, as well as its embassies abroad, did not respond to a request for comment Thursday from The Associated Press. Officials at Sinopharm could not be immediately reached.
The Wall Street Journal in its Thursday edition quoted Waleed Khalifa al-Manea, Bahrain’s undersecretary of health, as describing Sinopharm as providing a high degree of protection. But he acknowledged offering Pfizer to those with special needs, without explaining why the kingdom made that decision.
The two shots use different technologies. The Pfizer shots, a so-called “mRNA vaccine,” contain a piece of genetic code that trains the immune system to recognize the spiked protein on the surface of the virus. The Sinopharm vaccine is an “inactivated” shot made by growing the whole virus in a lab and then killing it.
The United Arab Emirates and Bahrain, both of which heavily relied on Sinopharm in their initial vaccination drives, announced in May that they’d offer a third shot of the Sinopharm vaccine amid concerns about an insufficient antibody response. China’s top disease control official acknowledged in April that the country’s locally produced vaccines offer low protection against the virus, adding to growing questions over the shot’s efficacy.
The World Health Organization granted the Sinopharm shot emergency approval in May, potentially paving the way for millions of doses to reach needy countries through the U.N.-backed COVAX vaccine program. A range of governments, including in Hungary, Pakistan, Serbia and the Seychelles, an island nation in the Indian Ocean, already administer Sinopharm.
In March, an official from a state-linked Emirati company distributing Sinopharm set off a storm of confusion when he acknowledged on Dubai’s state-owned radio that “a very small number” of residents had already received booster shots of Sinopharm. As vaccine recipients became worried about their antibody levels, authorities cautioned the public against mixing different coronavirus vaccines.
In April, the head of international cooperation at China National Biotec Group, which is a subsidiary of Sinopharm, described the UAE’s use of booster shots as “not included in our clinical plan.”
In the UAE, home to Abu Dhabi and Dubai, some who earlier received Sinopharm have later gone back to be re-inoculated with the Pfizer vaccine as it became widely available across the federation of seven sheikhdoms.
The UAE and Bahrain rank among the world’s top vaccinators on a per-capita basis. Yet Bahrain, home to some 1.6 million people, is in the throes of its worst wave yet of the virus, forcing the kingdom into a two-week lockdown.
Meanwhile Thursday, sovereign wealth funds in Russia and Bahrain announced the island kingdom would begin producing the Sputnik V vaccine to supply demand across the Middle East and North Africa.
