Moderna plans to test the Covid-19 vaccination one year after the first two vaccinations, as the timing of protection from the new vaccine is still unclear.
The biotech company plans to start a trial in July, according to a corporate presentation this week. Clinical trial locations have already begun contacting participants in previous studies based on emails they shared.
“From what we̵7;ve seen so far, I think our expectation is that vaccination will last at least a year,” Moderna’s Chief Medical Officer Dr. Tal Zaks told investors and analysts at the conference. JPMorgan Healthcare Conference on Monday. “At the level where you need a booster shot, we will give you advice based on information and that will require us to be informed.”
The first participant in Moderna’s human clinical trials was photographed in mid-March. One second was given four weeks later. Because previous trials tested multiple doses of the vaccine, those who received the vaccine at the lower doses that were ultimately allowed 100 micrograms were previously stimulated, while those with 100 micrograms or more. It will be stimulated at the year mark according to e-mail to the participants
The planned booster is now the same vaccine as commercially available, but Moderna CEO Stephane Bancel said in the coming years it may be necessary to adapt the vaccine to include new strains.
“I think this will become a flu-like marketing,” he told CNBC Moderna has just started a seasonal flu vaccine program as well.
An additional study for Moderna’s Covid-19 vaccine will assess both the safety and the amount of increased immune response a year later, Bancel said at a meeting this week.
