With coronavirus case numbers on the rise once again, the federal government has begun a renewed push to get vaccines in arms…but new data could hamper that effort.
As it stands today, approximately 70% of the population of the United States is vaccinated against COVID-19, with these vaccines proving to be somewhat efficient in preventing serious complications from the new delta variant of the virus.
But that might not last.
Three studies published Wednesday by the Centers for Disease Control and Prevention show that protection against the coronavirus given by vaccines declined in the midsummer months when the more contagious delta variant rose to dominance in the United States.
The news was not great.
“Examining numerous cohorts through the end of July and early August, three points are now very clear,” CDC director Rochelle Walensky said at a White House covid-19 news briefing Wednesday. “First, vaccine-induced protection against SARS-CoV-2 infection begins to decrease over time. Second, vaccine effectiveness against severe disease, hospitalization and death remains relatively high. And third, vaccine effectiveness is generally decreased against the delta variant.”
This could seriously hamper the Biden administration’s efforts in getting the vaccination rate into “herd immunity” territory, especially as Americans who were on the fence about receiving a first dose will now need to consider the possibility of extraneous doses being required in the near future.
