1st Patient Receives Pfizer-BioNTech COVID-19 Vaccine in the U.S.
Sandra Lindsay, a nurse at Long Island Jewish Medical Center is the first U.S. patient to receive the COVID-19 vaccine created by Germany’s BioNTech and U.S.-based Pfizer. Lindsay is a critical care nurse at the hospital in Queens, New York City.
She told CNN, “I feel hopeful today, relieved. I feel like healing is coming. This marks the beginning of the end of a very painful time in our country.”
Moderna
Moderna’s vaccine is up next, with the FDA’s vaccine adcom meeting on Thursday, December 17. If it moves like the Pfizer-BioNTech vaccine last week—and there’s no particular reason to believe it will be otherwise at this point—the vaccine will receive Emergency Use Authorization (EUA) sometime on Friday, December 18 or possibly Saturday the 19th, and distribution will begin over the weekend and someone somewhere in the U.S. will receive the first of the Moderna shots sometime on Monday, December 21.
So Then What?
The Pfizer-BioNTech and Moderna vaccines, both mRNA vaccines, require two doses about 28 days apart. It seems to take a couple weeks to build up some immunity—typical of most vaccines—and although the second shot is needed to grant the full potential of the vaccine, both of which in clinical trials demonstrated about 95% efficacy, the clinical trials have suggested that some immunity begins in a week or so of the first injection. So people receiving the shot should still continue wearing masks, practice social distancing, and wash their hands thoroughly and regulatory.
CureVac Launches Phase IIb/III Trial of its Own COVID-19 Vaccine
Germany’s CureVac announced it has enrolled the first volunteer in the pivotal Phase IIb/III trial of its own mRNA vaccine candidate, CVnCoV against COVID-19. In early-stage trials, the vaccine was generally well-tolerated at all doses and induced strong antibody responses as well as the first indication of T-cell activation. The immune response was similar to that observed in recovered COVID-19 patients. The trial will utilize a 12-microgram dose.
The Phase IIb/III trial, dubbed HERALD, will include more than 35,000 volunteers in Europe and Latin America. The HERALD trial will begin with the Phase IIb section, which is expected to merge directly into the Phase III efficacy portion. Participants 18 years or older will receive a two-dose regiment of either the vaccine or a placebo.
Leading Vaccines
Although so much attention has been paid to Pfizer-BioNTech, Moderna and the AstraZeneca-University of Oxford COVID-19 vaccines, they are not the only ones in late-stage trials. Although it’s hard to say what will happen to some of the later-developing vaccines as the frontrunners are rolled out and the pandemic begins to ebb, but many that will have vaccines available in 2021 will presumably help with limited manufacturing of the Pfizer-BioNTech, Moderna and AstraZeneca-Oxford vaccines. Here’s a few others:
CanSino—In limited use in China.
Gamaleya—Russia’s Sputnik V vaccine, which has also begun early use in Russia. AstraZeneca is also going to test their own vaccine in combination with Sputnik V.
Johnson & Johnson—Currently in Phase III trials, with interim data expected sometime in March.
NovaVax—Phase III
Vector Institute—In limited use in Russia, but is otherwise in Phase I and II trials.
Sinopharm-Beijing—Approved in the United Arab Emirate (UAE), Bahrain, and limited use in China.
Sinopharm-Wuhan‑Limited use in China and the UAE.
Sinovac—Limited use in China.
AnGes—This Japanese company is currently running Phase II/III trials with Osaka University and Takara Bio.
Medicago & GlaxoSmithKline—Canada-based Medicago, partially funded by cigarette maker Philip Morris, grows vaccines in a wild species of tobacco, Nicotiana benthamiana. It is currently in a Phase II/III clinical trial.
Anhuei Zhifei Longcom and the Chinese Academy of Medical Sciences—Currently in Phase III.
Bharat Biotech—In collaboration with the Indian Council of Medical Research and the National Institute of Virology, the Indian company’s Cvaxin is in Phase III trials.
