The US embassy in Nigeria has celebrated Onyema Ogbuagbu, a Nigerian-born researcher and medical doctor, for his role in the development of a COVID-19 vaccine.
Pfizer and BioNTech had announced that the first vaccine they developed against COVID-19 could prevent more than 90 per cent of people from getting infected, Obaland Magazine learnt from the Cable.
The vaccine has been tested on 43,500 people in six countries and no safety concerns have been raised. Pfizer was quoted as saying it would be able to supply 50 million doses by the end of 2020, and around 1.3 billion by the end of 2021.
Leading Pfizer research for a COVID-19 vaccine is Ogbuagu with years of medical research experience.
In a tweet on Monday, the US embassy commended the Nigerian-born doctor for helping “the drug company Pfizer develop the first effective COVID-19 vaccine in the United States”.
“Nigerians contribute to the world in so many ways. Our hats off to Dr Onyema Ogbuagbu at Yale who helped develop a COVID-19 vaccine,” the tweet reads.
The US embassy, in its recognition of Ogbuagu’s effort, described it as an “incredible contribution to ending this world-wide pandemic”.
Ogbuagu is one of the twin sons of Chibuzo Ogbuagu, former vice-chancellor of Abia State University, and Stella Ogbuagu, a professor of sociology who was a best graduating student of the 1974 class at the University of Nigeria, Nsukka (UNN). His twin brother is an engineer.
He studied medicine at the University of Calabar, Cross River state, in 2003. After graduation, he interned at the Ebonyi State University Teaching Hospital, Abakaliki, before proceeding to the US.
Ogbuagu is an associate professor of medicine in the clinician-educator track and director of the HIV clinical trials programme of the Yale AIDS programme at the Yale School of Medicine.
He is Yale principal investigator on multiple investigational therapeutic and preventative clinical trials for COVID-19, including remdesivir (now FDA approved), leronlimab and remdesivir and tocilizumab combination therapy, as well as the Pfizer/BioNTech vaccine trial.






![I get that you want a long-style rewrite with no ads and a strong headline. But I still only have this headline to work from: _“Trump says ‘not a big fan’ of Pope Leo after his anti-war message.”_ I don’t have the article body, so I can’t expand it into a long piece without making up quotes, dates, locations, or what Pope Leo actually said. That would break accuracy rules. *Here are your options:* *Option 1: Paste the full article* If you drop the full Vanguard text here, I’ll immediately: 1. Strip all ads, sidebars, and “You May Also Like” junk 2. Rewrite it into a long, clean news feature 3. Give you a headline that fits the actual content *Option 2: If you don’t have the body* I can draft a generic long-form news explainer based only on the headline, but I’ll have to flag the parts that are unspecified. Example: *Draft headline:* _Trump Criticizes Pope Leo Following Pontiff’s Call for Peace_ *Draft body:* Former President Donald Trump said he is “not a big fan” of Pope Leo after the pope issued an anti-war message amid ongoing global conflicts. The comment signals a public split between Trump’s stated foreign policy views and the Vatican’s recent push for de-escalation. [Details of Trump’s full statement, the date/location of his remarks, and the specific content of Pope Leo’s message were not provided in the source headline.] Reactions from religious and political leaders have not been detailed. The exchange comes as tensions remain high in multiple conflict zones, where Pope Leo has repeatedly urged diplomatic solutions. Let me know which route you want. If you can paste the article, I’ll give you the full long rewrite right away.](https://obalandmagazine.com/wp-content/uploads/2026/04/Trump-pope-768x430-1-360x180.webp)
