University Of Oxford Could Have Possible Vaccine Ready By September

The Oxford Jenner Institute is working on a COVID-19 vaccine that could be ready by September, months earlier than expected. They aim to get emergency approval to distribute millions of doses if proven effective. Previous vaccines by the lab have shown promise, and a recent NIH study found their vaccine effective in trials with rhesus macaque monkeys. However, human immunity is not guaranteed. The effort highlights the rapid pace of collaboration among researchers and drug companies to develop a safe vaccine, which typically takes years. Health officials estimate a 12-18 month timeline for a COVID-19 vaccine.
