“It might be the next best thing to a coronavirus vaccine,” writes the Los Angeles Times. “Scientists have devised a way to use the antibody-rich blood plasma of Covid-19 survivors for an upper-arm injection that they say could inoculate people against the virus for months.”
Using technology that’s been proven effective in preventing other diseases such as hepatitis A, the injections would be administered to high-risk health care workers, nursing home patients, or even at public drive-through sites — potentially protecting millions of lives, the doctors and other experts say. The two scientists who spearheaded the proposal — an 83-year-old shingles researcher and his counterpart, an HIV gene therapy expert — have garnered widespread support from leading blood and immunology specialists, including those at the center of the nation’s Covid-19 plasma research.
But the idea exists only on paper. Federal officials have twice rejected requests to discuss the proposal, and pharmaceutical companies — even acknowledging the likely efficacy of the plan — have declined to design or manufacture the shots, according to a Los Angeles Times investigation… There is little disagreement that the idea holds promise; the dispute is over the timing. Federal health officials and industry groups say the development of plasma-based therapies should focus on treating people who are already sick, not on preventing infections in those who are still healthy…
But scientists who question the delay argue that the immunity shots are easy to scale up and should enter clinical trials immediately. They say that until there’s a vaccine, the shots offer the only plausible method for preventing potentially millions of infections at a critical moment in the pandemic. “Beyond being a lost opportunity, this is a real head-scratcher,” said Dr. Michael Joyner, a Mayo Clinic researcher who leads a program sponsored by the Food and Drug Administration to capitalize on coronavirus antibodies from COVID-19 survivors. “It seems obvious.” The use of so-called convalescent plasma has already become widespread. More than 28,000 patients have already received the IV treatment, and preliminary data suggest that the method is safe.
