When did you receive your second dose of Covid vaccine? You might be more vulnerable to the Delta variation.
The diminishing efficiency of the immunizations has heightened fears that the winter will serve as an incubator for the Delta type of coronavirus. Professor Tim Spector, chief scientist of the ZOE COVID Study, warned that depending on when you had your second dosage of either AstraZeneca or Pfizer, you may be more “worse off” now against the Delta variety.
The early protection provided by both the Pfizer and AstraZeneca vaccines makes the rationale for COVID-19 vaccination unmistakable. The vaccines have been proven to be effective against the Delta strain, which is significantly more transmissible than previous mutations. However, research has revealed that the vaccinations’ potency decreases as time passes after the second dose.
This alarming tendency has prompted several scientists to provide pessimistic predictions for the next winter, when high-risk individuals may be exposed to a resurgent virus.
Professor Tim Spector, chief investigator at the ZOE COVID Study, revealed in a recent video how the time period following your second Covid vaccine injection makes you “worse off” against Delta.
He made his claims based on over 1.2 million test results and volunteers, making it one of the largest real-world vaccine effectiveness studies ever conducted.
The researchers checked to see if any of these persons reported a positive COVID test result between May 26 this year, when the Delta form became popular in the UK, and the end of July to assess the second dosage effectiveness, or how long they are protected.
According to professor Spector, both the Pfizer and AstraZeneca vaccines had “really good efficacy for the first month” of roughly 80-90 percent, but “as each month goes on, you can see that diminishing benefit.”
He pointed out the linear curve or drop off that appears to be continuing on a chart.
Prof Spector said that the rapid drop appears to be four to five months for AstraZeneca and five to six months for Pfizer.
As a result, you’re “worse off four to six months after both immunizations than you were at the start,” he said.
It’s vital to highlight that these data have been modified to reflect a population-wide reduction in infection risk.
“However, because we are all unique and our immune systems may react to the vaccine in different ways, individual levels of.”Brinkwire Summary News”.
