Washington: Complete Vaccination against Covid-19 is very effective in preventing hospitalization, an emergency department visit, and acceptance of intensive care due to viral infections, according to a study involving data from nearly 200 hospitals around the US.
Real evidence, published in the New England Journal of Medicine on Thursday, is collected from the Electronic Health Records (EHRS) which shows that vaccines provide a high level of protection for populations that are disproportionately influenced by viruses.
US centers for controlling and prevention of disease (CDC) collaborate with six US health care systems plus Regenstrief Institute, to create a vision network to assess the effectiveness of Covid-19 vaccine.
All of these institutions contribute to hospitalization and ICU data for patients over 50 years of a total of 187 hospitals, in addition to data from the emergency department and urgent care clinic.
Data analysis showed vaccination MRNA two doses – modern and pfizer – was 89 percent effective to prevent covid-19 inpatient care, and 91 percent effectively to prevent emergency departments or urgent care visits.
Vaccination of two doses of 90 percent effective to prevent the receipt of the Covid-19 intensive care unit, the researchers said.
The effectiveness is significantly lower in individuals who only receive the first dose of two shot vaccinations, they said.
“This study confirmed that this vaccine was very effective,” said the main author of the author Mark Thompson, member of the CDC response team Covid-19.
“They offer significant protection for people who are older than 85, people with chronic medical conditions, as well as black and Hispanic adults.
Everything is a group that has been hit very difficult by this disease,” Thompson said.
The researchers said they hoped this findings would convince more people to vaccinate to protect not only themselves, but their community.
The study also sees the effectiveness of Johnson and Johnson dose vaccines.
Found 73 percent effective against the emergency department and urgent care visits, and 68 percent of hospitalization.
However, the research writer noted that smaller sample size could affect this accuracy of estimates and stated that more data needed.
“This real world evidence strengthens the results of clinical trials and provides more confidence in the vaccine,” said the paper research writer Shaun Grannis, a professor at the University of Indiana Medical School, USA.
