Research shows, what people, survivors of Covid-19, should receive another single dose of the coronavirus vaccine.
New research shows, that one shot of the vaccine can significantly increase the level of antibodies in those, who recovered from coronavirus.
By now, almost 30 million people in the United States and probably, a lot others, whose diseases have never been diagnosed.
Should Coivd-19 Vaccines Still Be Vaccinated??
Two new studies provide a strong answer to this question..
Actually, studies show, that these people only need one dose of vaccine, to boost their antibodies and wipe out the coronavirus - and even some other infectious variants.
The new research findings are consistent with the findings of the other two., published in the last few weeks. Taken together, studies show, what people, survivors of Covid-19, should be immunized, and one dose of vaccine may be sufficient.
Human immune response to natural covid-19 coronavirus infection varies greatly. Most people develop large amounts of antibodies., which persist for many months. But some people, who have had mild or no symptoms of Covid-19, produce few antibodies, which quickly fall to an undetectable level.
One vaccine will not help African Crown B.1.351.
In the latest study, which has not yet been published in a scientific journal, human blood samples were analyzed, survivors of Covid-19. Results showed, that their immune system will have problems reflecting B.1.351, variant of coronavirus, first identified in South Africa.
But one shot of Pfizer-BioNTech or Moderna vaccine changed the picture significantly: he increased the number of antibodies in their blood a thousand times.
Filled with antibodies, samples from all participants could neutralize more than B.1.351, but also coronavirus, caused the SARS epidemic.
Actually, antibodies worked better, than people, who did not get the first Covid-19 and received two doses of the vaccine. Numerous studies have shown, that Pfizer-BioNTech and Moderna vaccines are about five times less effective against this option.
The specialists took blood samples from 10 volunteers at the Seattle Covid-19 Cohort Research Center, who were vaccinated a few months after being infected with the coronavirus. Seven participants received the Pfizer-BioNTech vaccine, and three for the Moderna vaccine.
Blood, taken about two to three weeks after vaccination, showed a significant jump in the amount of antibodies compared to the samples, collected before vaccination.
Researchers don't know yet, how long the increased antibody count will last, but we hope, that they will last for a long time.
