Vaccine Stocks Checkup: Johnson & Johnson COVID-19 Vaccine Paused

See the latest news for the top companies producing COVID-19 vaccines including Johnson & Johnson, AstraZeneca, Pfizer, Moderna, and more.

The Centers for Disease Control and Prevention and the Food & Drug Administration announced Tuesday that they have suspended the use of Johnson & Johnson’s COVID-19 vaccine out of an abundance of caution due to a rare blood clotting side effect.

The CDC and the FDA said they will stop using the drug, developed by J&J's Janssen Pharmaceuticals division, at federal vaccination sites after six people were found to have developed a rare blood clot issue within two weeks of receiving the single-dose shot. CDC data indicates 6.8 million doses of the vaccine have been administered as of April 12.

Johnson & Johnson's  (JNJ) - Get Johnson & Johnson Report vaccine -- which was approved by the FDA last month -- had formed a key part of the government's vaccine rollout, as it's a single-shot regime that requires standard refrigeration temperatures, compared to the ultra-cold conditions required for Pfizer and Moderna's two-shot doses.

CDC from Monday showed that nearly 190 million Americans have received at least one dose of either the Pfizer, Moderna, or Johnson & Johnson vaccines, with around 64 million people -- the majority of them over 65 -- now considered fully vaccinated. 

Regeneron  (REGN) - Get Regeneron Pharmaceuticals Inc. Report reports progress in a Phase 3 trial of its Regen-COV antibody cocktail, which it is testing to prevent COVID-19. The Tarrytown, N.Y., pharmaceutical company's Phase 3 trial gave the drug to "recently infected" asymptomatic people. 

"Regen-COV reduced the overall risk of progressing to symptomatic COVID-19 by 31% (primary endpoint), and by 76% after the third day," Regeneron said in a statement. "The trial also demonstrated that Regen-COV shortened symptom duration and markedly reduced viral levels."

Regeneron said it will ask the U.S. Food and Drug Administration to expand the drug's authorization among people exposed to the virus who haven't yet been vaccinated.

This “could provide temporary stopgap protection as people await vaccines,” The company added.

This comes at a time when the number of new COVID-19 infections in the U.S. is continuing to surge in many states, amid vaccinations, after a lull earlier this year.

This past week, the U.S. logged more than 62,000 new infections, bringing the nation's total known infections closer to 31 million, according to data from Johns Hopkins. Scientists are also closely tracking new variants of the virus as they emerge, but no actual new "strain" -- using the narrow definition of the term that requires a variant to have significant biological differences -- has emerged so far.

States such as Michigan, Minnesota, and Nebraska have been seeing particularly worrying upward trends in new infections. The disease has been creeping up steadily in places like Massachusetts, New Jersey, New York, Delaware, and Florida, too.

Globally, nearly 131 million cases have been documented, with nearly 3 million deaths since the outbreak began over a year ago. And, the U.S. has seen nearly 555,000 deaths so far. 

Chembio Diagnostics  (CEMI) - Get Chembio Diagnostics Inc. Report shares spiked this past week as the company launched a test that can differentiate between COVID-19 and influenza. Chembio said the rapid immunoassay test produces results in 15 minutes and requires no instrumentation.

Pfizer and BioNTech recently reported that testing indicated the vaccine was effective against the potent South African variant of the illness.

Top-line results from a Phase 3 analysis of 927 symptomatic cases of COVID-19 showed the companies’ vaccine, BNT162b2, was 91.3% effective, measured seven days through up to six months after the second dose, they said.

Also this past week, the companies said they would work to boost the manufacturing capacity of the vaccine to 2.5 billion doses by the end of the year.

Two weeks ago, Pfizer said it had begun human safety testing of a new pill that could be used to treat COVID-19 when symptoms first occur.

This matched similar results announced recently for the vaccine developed by BioNTech and Pfizer.

Interim results from a trial of 33 healthy patients treated with Moderna's mRNA-1273 vaccine indicated 94% efficacy in preventing COVID-19.

Antibody activity remained high in all age groups -- participants ranged between 18-55, 56-70, and 71+ -- for 209 days. Nearly all participants had evidence of COVID neutralization.

Moderna announced this past week that David Meline, Chief Financial Officer, and Lavina Talukdar, Senior Vice President & Head of Investor Relations, will participate in a fireside chat at the 20th Annual Needham Virtual Healthcare Conference on Apr. 15.

The agency said it was investigating these cases and will decide whether regulatory action may be necessary, which usually consists of an update to the product information.
