Not a few experts worry that the Corona virus can become like influenza, which still needs a new vaccine every year because it mutates rapidly and immunity from vaccines has ended.
Although preliminary evidence suggests immunity from vaccination against the Coronavirus provides long-lasting protection, vaccine makers have started to build and test a version of their vaccine against whether it protects against this worrying virus variant.
This includes version B.1.351 first seen in South Africa, which appears to allow it to slightly evade the human immune response.
Chunhuei Chi, director of the Center for Global Health at Oregon State University, said how long antibodies last after a vaccine is a complex question and there is not much data available to answer it.
“Reports from previous clinical trials show that the immunity will last at least six months,” said Chi, quoted from Bloomberg.
“Many experts have a more optimistic estimate of the duration of immunity, based on research findings from people recovering from COVID-19 infection. They found that immunity caused by the infection can last eight months or even longer, especially for people who are infected and experience symptoms. the worst, “he continued.
Some time ago, Pfizer-BioNTech released data that supported the Chi assumption. They said their vaccine was 91.3 percent effective in preventing symptomatic cases from one week after the second dose for up to six months.
Lana Dbeibo, an infectious disease expert at Indiana University School of Medicine, says it’s possible we need a booster vaccine like we do for flu shots.
“If this is the case, how long is the distance between the initial vaccination and the booster dose, it is not yet known,” he said.
Until now, we still have a lot of people who haven’t been vaccinated. The fact that you’ve been vaccinated doesn’t change anything any time soon.
The public still has to take many of the same precautions as those who have not been vaccinated.
