Johnson & Johnson testing COVID-19 vaccine in adolescents between 12 and 17 years old

Johnson & Johnson has expanded a clinical trial of its experimental coronavirus vaccine to include adolescents 12 to 17 years old, the drugmaker announced Friday.

The ongoing, placebo-controlled trial was initially designed to evaluate the safety and efficacy of the shots for people ages 18 and older.

The company now plans to test its vaccine in “a small number” of 16- and 17-year-olds before expanding it to a larger pool of younger volunteers, according to a news release.

“The COVID-19 pandemic has had a profound impact on adolescents, not just with the complications of the disease, but with their education, mental health, and wellbeing,” Dr. Paul Stoffels, chief scientific officer at Johnson & Johnson, said in a statement.

“It is vital that we develop vaccines for everyone, everywhere, to help combat the spread of the virus with the goal to return to everyday life,” he said.

Johnson & Johnson’s coronavirus vaccine was the third to receive emergency use authorization. Unlike Pfizer’s and Moderna’s two-dose vaccines, Johnson & Johnson’s shots requires only one jab to be effective.

As part of the extended trial, the New Jersey-based drugmaker also plans to evaluate different dose levels and vaccination schedules, including two-and three-month intervals between shots.

The company is currently enrolling teenage participants in Spain and the U.K., with additional enrollment opening up “shortly” in Argentina, Brazil, Canada, the Netherlands and the U.S., according to the release.

Friday’s announcement comes days after Johnson & Johnson revealed that 15 million doses of its vaccine were spoiled at a Baltimore facility several weeks ago. The shots were ruined after workers accidentally mixed up some of the ingredients with those of the AstraZeneca vaccine. The incident was not expected to affect current shipments of Johnson & Johnson’s vaccine.

As of Friday morning, more than 56 million people in the U.S. have been fully vaccinated. Nearly 100 million have received at least one shot, according to data by the U.S. Centers for Disease Control and Prevention.

  • One of Taiwan’s Allies Weighs Embracing China for Vaccines

    (Bloomberg) -- As poor nations struggle to get their hands on Covid-19 vaccines, a thinly-populated South American country finds its chances linked to its unexpected role in growing tensions between the U.S. and China.Paraguay’s 63-year-old alliance with Taiwan — forged when both were run by right-wing authoritarians — means the government can’t directly buy from China’s vaccine makers that have supplied other Latin American nations. Officials say they’ve been approached to switch to Beijing to get the doses.U.S. Secretary of State Antony Blinken phoned President Mario Abdo Benitez to stiffen his spine against such a shift. That led Foreign Minister Euclides Acevedo to speak frankly this week to Washington and Taipei.“Mr. Blinken has been very firm, telling Abdo: ‘Look, your allies are Taiwan and us,’” Acevedo said on television. “But we ask these strategic allies for proof of their love. Before holding hands, you have to at least take us to the movies.”Acevedo warned that “countries with which we don’t have diplomatic relations” are actively courting other nations with vaccines. “President Xi Jinping has a lot of interest in a tie-up with us.”Asked to respond, a State Department spokesperson said the U.S. is working with Paraguay and like-minded partners to support pandemic response efforts and praised Taiwan as a leading democracy and partner.China’s Communist Party views Taiwan as its territory, which must be taken by force if necessary and often shuns countries that recognize it as independent. The government in Taipei rejects Beijing’s claim, insisting Taiwan is already a de facto sovereign nation.“As Taiwan loses allies, China’s claim gains more and more legitimacy,” said Francisco Urdinez, a researcher at the Catholic University of Chile’s Asian studies center and coauthor of a paper on Paraguay’s relationship with Taiwan. “If no country recognizes Taiwan, it will be much easier for China to reclaim possession of the island.”For years, as China developed into one of the world’s biggest markets, the vast majority of capitals chose Beijing over Taipei, meeting symbolic objection from Washington, which was also increasing its Chinese ties. But as Beijing’s global ambitions have grown, the U.S., both under President Donald Trump and now Joe Biden, sees it as a menacing rival, and Taiwan as needing more support.Meanwhile, the U.S. and European Union are holding onto their vaccines while China has provided millions to countries such as Mexico, Chile and El Salvador in a display of soft power.With its hospitals overwhelmed and deaths rising, Paraguay, which has a population of 7 million, has only been able to obtain 163,000 doses, including 23,000 Chinese shots donated by Chile and the United Arab Emirates. Benitez has faced weeks of protests and a failed impeachment motion due to the shortages.The Paraguay China Chamber of Industry and Commerce, known as CPCIC, is one of dozens of intermediaries that have approached the beleaguered administration offering to broker a vaccine deal. While some middlemen have asked for multimillion-dollar down payments, the chamber -- acting on behalf of a local pharmaceutical company -- wants health authorities to sign Chinese paperwork so the firms can start negotiations.“We basically said: If Paraguay’s government wants to fill out the forms, we could submit them for approval by Sinovac or Sinopharm,” the chamber’s president Charles Tang said of a letter CPCIC sent to the health ministry last week. The chamber said the government responded with questions.Paraguay belongs to a shrinking list of 15 countries, including Guatemala and Honduras, that recognize Taiwan. When its foreign ministry said that several third parties hinted that breaking with Taiwan was a precondition to obtain Chinese vaccines, China called it “malicious” misinformation. Taiwan, in turn, accused “some parties” of using vaccines for “political manipulation.”The relationship between the two countries dates back to when anti-communist presidents Alfredo Stroessner and Chiang Kai-shek ruled in Asuncion and Taipei. They never met. Stroessner paid a state visit to Taiwan in 1975 accompanied by his personal secretary, the father of Benitez. Taiwan has showered hundreds of millions of dollars in aid on its ally over the years, but bilateral trade is tiny compared to Paraguay’s other trading partners.Among other things, Taiwan has donated to Paraguay badly needed Covid drugs and medical supplies, allowing the government to redirect housing aid to buy vaccines.Even so, the pandemic is giving fresh impetus to those among the country’s business and political elite who say it’s long past time to abandon Taiwan.Paraguay’s support of Taipei has sidelined it from public works financing under China’s Belt and Road initiative. Last year, China enjoyed a trade surplus of almost $2.9 billion with Paraguay, which can’t directly sell it beef and soy.Over the past year, left-wing and conservative opposition parties have sponsored two non-binding resolutions to establish diplomatic relations or directly negotiate the purchase of medical supplies and vaccines with China. While the ruling Colorado Party voted down or heavily amended the resolutions, some of its lawmakers are starting to question the party’s longstanding support of Taiwan.China’s pandemic aid to its allies made an impression on Jazmin Narvaez, who leads the Colorado Party faction in the lower house loyal to Benitez.“There isn’t a raging debate,” she said by telephone. “But several colleagues have doubts as to which alliance is in Paraguay’s best interests. It’s a situation that has to be studied.”Even the government has signaled that what was once an ironclad relationship could be subject to review. Minister Acevedo left the door open, saying, “That is a political debate that merits an agreement between all branches of government and society.”(Updates with analyst comment in paragraph 8)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.

    The European Union has asked India to allow it to buy 10 million doses of AstraZeneca's COVID-19 vaccine from Serum Institute of India, a government official told Reuters, the latest sign of growing pressure on Delhi to export more of its production to other countries. The EU wants the doses from Serum, the world's largest vaccine maker, to offset supply shortfalls from AstraZeneca's European plants and speed up the bloc's vaccine roll-out. Any quick approval of the EU request is unlikely, however, with India scrambling to expand its own domestic vaccination drive, said the Indian government official, who asked not to be named as the discussions are private.
