Scientists at the University of Georgia (UGA) are pioneering a new type of COVID-19 vaccine, one that could be conveniently taken as a nasal spray, and they’re making progress fast. 

The coronavirus nasal spray is currently under clinical trial at the Infectious Disease Lab at UGA.

Dr. Biao He, the lead researcher behind the vaccine breakthrough, spoke about being “excited” with the development as he explained the basis behind developing a nasal spray vaccine to Channel 2 Action News.

“Since so many pathogens come through the respiratory tract, and the idea is, wouldn’t it be easier if we just immunize through the route of infection,” He explained.

He’s team first got the idea of a nasal spray from dogs, who were often treated through such a method for coughs, and from other nasal sprays used to vaccinate against diseases like influenza. It led to He and his team to wonder if creating a nasal spray vaccine for COVID-19 would encourage and make it easier for people to get vaccinated.

“I really feel we are very, very fortunate that what we are doing turned out to be very good and has a great practical application,” He said.

The vaccine is currently in phase two of its FDA-approved clinical trial. There are a total of four phases to be cleared before the FDA can verify both the safety and effectiveness of the vaccine.

“We began working on new vaccine formulations to combat COVID-19 during the early days of the pandemic,” He said, “our preclinical data show that this vaccine not only protects against infection, but also significantly reduces the chances of transmission.”

Georgia Legislature approves coverage to help first responders cope with job-related PTSD treatment

The Ashley Wilson Act, named for Gwinnett police sergeant Ashley Wilson, passed unanimously in the Georgia House of Representatives, aiming to provide supplemental health insurance for first responders diagnosed with PTSD due to on-the-job experiences. This landmark legislation, celebrated for its potential to significantly aid in the recovery and support of traumatized first responders, reflects a broader recognition of PTSD’s serious impact on public safety personnel, promising financial and treatment support beginning January 1, 2025.

FAFSA delays pose challenges for Georgia college-bound students

Students across Georgia are facing delays in the Free Application for Federal Student Aid (FAFSA) process, particularly challenging due to its late January rollout and additional complications for mixed-status families. Despite these setbacks, the Department of Education has implemented fixes for major issues, and officials, including MorraLee Keller of the National College Attainment Network, urge students not to give up on securing financial aid for college.
