IS THE CONTAGION OF THE VACCINE DECREASING?

A study of thousands of British scientists has produced promising results on covid-19 contagion. What the results mean, so we asked the expert.

  • Experts, who often emphasize the importance of vaccination as part of the fight against the Covid-19 pandemic, say that we need to be vaccinated to protect not only ourselves, but also those around us.
    .
  • The study conducted by the Public Health Administration (PHE), the top health-related body in the UK, and the results of which were announced on 27 April, provided crucial data to support this message.
    .
  • A study of thousands of people who received Pfizer/BioNTech and AstraZeneca vaccines administered in the country found that even a dose of the vaccine almost halved the likelihood that individuals would infect people in their immediate vicinity.

.
ALTHOUGH THOSE WHO ARE VACCINATED ARE INFECTED, THEY ARE LESS INFECTED

  • According to research results cited in UK press reports, people who have spent 21 days or more since receiving a dose of the vaccine are 38 percent less likely to infect people with the virus at home than those who have not been vaccinated, and 49 percent less likely to be infected with the AstraZeneca vaccine and the Pfizer/BioNTech vaccine.
    .
  • Infection prevention begins on the 14th day after the vaccine is administered. How old a person is is not an important factor in the point of transmission protection. The rate at which un-vaccinated individuals infect those at home after being infected is 10 percent.
    .
  • At the next stage of the research, experts will look at whether the administration of two doses of the vaccine further reduces the likelihood of infection with the virus. In the same way, it will be examined whether the protection of vaccine-induced transmission applies in places outside the home. PHE hopes to achieve similar results in places where people live together, such as dormitories, care homes or prisons, and where there is a high risk of transmission.

.
CONTACTS OF THOSE WHO WERE VACCINATED AND THOSE WHO WERE NOT WERE COMPARED

  • More than 57 thousand people living in 24 thousand households were examined within the scope of the research, which has not yet passed the arbitration audit. All of these people were in contact with vaccinated people. The results of these people were compared to those of 1 million people who were not vaccinated.
    .
  • The concept of contact was defined as secondary coronavirus cases that tested positive for PCR Within 2 to 14 days after the first Covid-19 case in the house. Most of those surveyed were under the age of 60.
    .
  • PHE immunity Director Dr. “While these findings are quite promising, it is important that you act as if you are carrying the virus, take care of hand hygiene and follow the rules of social distance, even if you are vaccinated,” said Mary Ramsay, evaluating the results.

.
SECOND STUDY WITH SIMILAR RESULTS

  • Another study conducted in the UK recently showed similar results. A study conducted in collaboration with the University of Oxford and the Office for National Statistics showed that vaccination prevents transmission.
    .
  • A review of real-life data showed that those vaccinated with Pfizer/BioNTech or AstraZeneca vaccines experienced up to two-thirds decreases in contagion after the first dose. Especially in those with the second dose of the Pfizer/BioNTech vaccine, this ratio was even higher.

.
WHAT DO THE RESULTS TELL US?

The results of this research conducted by PHE, Infectious Diseases and clinical microbiology specialist Prof. Dr. and Turkey Medicals member, rated it for our readers.

  • Prof. Dr., by specifying that the vaccine are effective in preventing transmission of all kinds of mRNA vaccines in the first dose spreads partially reduced, inactive vaccines and Vector stressed that the work that the two doses should be applied to achieve this result.

.
A SINGLE DOSE OF VACCINE PROVIDES A CERTAIN AMOUNT OF PROTECTION

  • “In some studies, it has been shown that mRNA vaccines also have a protective rate after the first dose and prevent transmission at a certain rate, but we cannot say this for inactive virus vaccines,” said Prof. Dr, ” there are no scientific studies on the effects of inactive virus vaccines in terms of contagion. For this reason, we can say that the infection decreased after two doses of the vaccine,” he said.

.
NOT ENOUGH DATA ON VECTOR VACCINES

  • Prof. Dr., who also evaluated the effects of the Sputnik V vaccine on contagion, which will be introduced soon in Turkey, said: “We do not have enough data on how much Vector vaccines prevent contagion after the first dose. For this reason, as indicated in Phase 3 studies, two doses of the vaccine must be made to prevent sufficient contagion,” he said.

.
SINGLE-DOSE MRNA VACCINE CAN LARGELY PREVENT DOMESTIC TRANSMISSION

  • Prof. Dr., the vaccine is effective in preventing all kinds of transmission, stating, “The sooner society becomes immune, the sooner the chain of outbreaks will be broken. A double dose is required for inactive vaccines to prevent domestic transmission, but with a single dose in mRNA vaccines, we largely prevent all transmission, not just domestic transmission,” he said.
