mRNA vaccines train our body to produce antibodies against viral proteins. Researchers found that these vaccines are highly effective in reducing the duration of COVID-19 illness.

‘Individuals who got an mRNA vaccine experienced milder COVID-19 symptoms and a 60% reduction in the rate of sickness than the unvaccinated ones.’

mRNA vaccines introduce a piece of viral genetic material into our body and teach it to synthesize antibodies against the proteins produced by viral genes. Pfizer-BioNTech and Moderna used this cutting-edge technology and released two-dose mRNA vaccines that help create an effective immune response against SARS-CoV-2. 




The current study by the HEROES-RECOVER network enrolled 3,975 people from eight sites, including Salt Lake City, Miami, Temple, Portland, Duluth, Phoenix, Tucson, and other areas in Arizona. The participants provided samples for RT-PCR tests weekly and reported symptoms related to COVID-19, including fever, shortness of breath, and loss of taste and smell, if any, for 17 weeks.
The vaccination status of the participants was continuously monitored and recorded via electronic and telephone surveys and through direct upload of images of vaccination cards.
Based on the RT-PCR results and calculations related to vaccine effectiveness, the researchers found that about 204 people out of 3,975 participants tested positive for COVID-19, of which 156 were unvaccinated, and 16 were fully vaccinated.
Vaccinated individuals experienced only milder symptoms of COVID-19, and the rate of sickness was reduced by 60% among them when compared to the unvaccinated ones. Also, the presence of detectable viral particles in these individuals showed a 70% reduction from 8.9 days to 2.7 days.
