As COVID-19 vaccines are progressing at a record rate, and more than one in four U.S. adults is now fully vaccinated, according to the latest figures from the Centers for Disease Control & Prevention (CDC), some may question whether still needed. after receiving jabs.
“People who have been fully vaccinated should test whether they develop symptoms of COVID, or if they think they have had significant exposure,” said Dr. Anna P. Durbin, a professor at Johns Hopkins University School of Medicine and Johns Hopkins Bloomberg School of Public, said. Baltimore Health, which specializes in infectious diseases and vaccinations, sent an email to Fox News.
The CDC also suggests that people who are fully vaccinated can survive without testing and quarantine after exposure if they do not develop symptoms.

“If symptoms develop, all individuals – regardless of vaccination status – should be isolated and clinically evaluated for COVID-19, including SARS-CoV-2 testing, if indicated,” the CDC said.
The guidelines differ for those in community environments (such as correctional facilities and group homes) due to turnover rates, increased risk of spreading viruses, and difficulty maintaining distance. In these cases, the agency recommends a 14-day quarantine and tests for possible exposure.
As Durbin explains, vaccines are designed to protect against diseases, especially for respiratory viruses. Evidence from clinical trials has shown that the recently approved vaccines developed by Pfizer and Moderna are approximately 95% effective in preventing the symptomatic COVID-19, and real-world data indicate that the mRNA vaccines increase the risk of infection by 90%. reduce. Johnson & Johnson previously said the single-shot coronavirus vaccine was 72% effective in preventing moderate to severe COVID-19 in the US, but dropped to 66% in a larger trial worldwide. According to the CDC, early data suggest that the Janssen vaccine may also ward off asymptomatic transmission.
John Breakte, chief medical officer of the healthcare website WebMD, had earlier told Fox News that ‘breakthrough’ cases of COVID-19 – or, if they contract the virus, despite receiving the vaccine.
The vaccines are very good, he said, but “are not 100% effective.”

“Fully vaccinated should still pay attention to symptoms of COVID-19, especially after exposure to anyone who suspects or confirms COVID-19,” the CDC recommends. However, the federal health agency says the risk of becoming infected is ‘low’ for individuals who are vaccinated. With this, the CDC has already said that the test and isolation before and after the trip is not necessary for those who have completed their vaccinations.
“It is possible that people who have completed their vaccination series may still be infected with SARS-CoV-2; however, the infection rate after vaccination appears to decrease by 70-80% compared to the non-vaccinated population,” says Matthew Binnicker, Ph.D., director of the Clinical Virology Laboratory at Mayo Clinic’s Division of Clinical Microbiology, in an email to Fox News. “In the event that a vaccinated person becomes infected, they may shed lower amounts of the virus and for shorter periods of time compared to individuals who have not been vaccinated.”
