People who received the single-dose Johnson & Johnson vaccine will also probably need extra shots, health officials said. Health officials are likely to recommend that the booster be the same brand of vaccine that people received initially. Last week, U.S. health officials recommended a third shot for some people with weakened immune systems, such as cancer patients and organ transplant recipients. One of the studies looked at reported COVID-19 infections in residents of nearly 15,000 nursing homes and other long-term care facilities.
