COVID-19 VACCINE UPDATES
Public confidence in effectiveness and delivery of COVID-19 vaccines must be established for battle against the pandemic to succeed.
The worldwide effort to create a vaccine for the novel coronavirus kicked off in January, 2020 soon after scientists in China posted online the genome of a virus causing a mysterious pneumonia. Vaccine development usually takes years and unfolds step by step. Experimental vaccine candidates are created in the laboratory and tested in animals before moving into progressively larger human clinical trials.
These steps are now overlapping in the race to find a vaccine for a global disease that has killed hundreds of thousands of people. Human testing began in some cases before animal studies were finished. As companies launch small Phase 1 trials intended to establish the correct dose, they already are planning the Phase 3 trials that evaluate whether the vaccines are effective and safe.
