New COVID-19 vaccine clinical trials begin in Colorado Springs

COLORADO SPRINGS, Colo. (KRDO) -- The Lynn Institute of the Rockies is leading late-stage clinical trials in Colorado Springs for a new COVID-19 vaccine, beginning phase three trials of the Novavax vaccine on Monday.

"One of the things we're trying to ensure is that these vaccines are safe," Dr. Ripley Hollister said.

Hollister, who is also leading Moderna trials at the clinic, said they are currently enrolling about 300 volunteers for the study, which is part of a larger effort comprised of 30,000 participants in the U.S. and Mexico.

"In this study, the protocol will call for a 2 to 1 vaccine to placebo. So, basically 68% of the people who enroll in this trial will receive the active vaccine," Hollister said.

Participants must be over the age of 18 with a healthy medical history.

"The way that this study has been engineered is to mirror what's going on with the pandemic. So, it is pretty open."

According to Hollister, one significant difference between the Novavax and other vaccines is that it's protein based.

"This actually takes the whole process a step down the road. So, we don't give messenger RNA. We give the actual sort of analog of the spike protein. That spike protein then goes into the immune system and stimulates these blocking antibodies."

Early studies show antibodies developed from this vaccine were actually superior to those in patients developed from the virus.

Storage of the Novavax vaccine, Hollister said, is simpler too.

"The Pfizer vaccine, down on the far end of the spectrum, has to be stored 70 degrees below zero. Moderna is simple freezing. But the Novavax stays even one step easier, by just actual refrigeration."

However, like both Pfizer and Moderna, participants should expect mild symptoms.

"It does take a little bit out of you. In our first study, people would have mild symptoms for a day or so. We expect the same thing out of Novavax."

Volunteers interested in the trial must complete a form on the clinic's website.

  1. So far the Pfizer shot has been shown to Not work. Centura Health workers that were given the shot are still getting COVID and having all the same level of symptoms as people who didn’t. Centura discourages their employees to talk about this in order to encourage others to get the shot asap.
    This is a false sense of protection and many who got/get the shot will still get covid and die. So many people are led to believe it is a vaccine and once you get the shot you are protected.

    1. What are you talking about the earliest anyone was vaccinated was about three weeks ago, most of them would just now be getting their second dose of the vaccine. It takes about two weeks after your second dose before you have immunity.

      1. Not according to Pfizer. The initial shot is the “Vaccine” and to maintain the antibodies a “Booster shot” should be given on day 28 for longer protection.
