“If there are people who sign up but now have no contact at a higher level, are not at risk because of their disease or age, I would probably recommend that they take a look at the larger clinical trials, world practice, recommendations from manufacturers themselves, “Advisor to Defense Minister Justina Aleksaitė.
So far, the third dose of the vaccine in Lithuania can be vaccinated by 80 thousand people.
“For our population, where the largest vaccination was carried out in May-June, the problem with the weakening of the vaccine is likely to present itself in six months. So, it will be the beginning of next year,” said the data scientist Zemlys-Balevičius Vaidotas.
Lithuania was one of the first to initiate booster vaccination, although there are no recommendations from the manufacturers themselves, clearly stating that a booster dose is already needed for a certain amount of antibodies.
“The manufacturer of the drug offers recommendations for two doses and the recommended interval between them. The third dose will be decided by scientists and experts by analyzing the available data, ”said Co: Agency, official communications representative of Astra Zeneca.
There are questions about whether the third vaccine has not been rushed. One of the world’s most influential medical journals, The Lancet, writes that vaccinating with a third dose is not recommended yet, as there is a lack of evidence for the effectiveness of the booster shot. Also, the virus will mutate from the strains that are currently thriving, and a positive short-term effect does not necessarily mean that a booster dose will provide the same long-term effect.
“The announcement that a booster dose will be needed very soon, unless supported by reliable data and analysis, could negatively impact vaccine confidence and generally undermine understanding of the value of primary vaccination. “said the magazine.
The World Health Organization (WHO) has asked a little earlier that people not get vaccinated with a third dose until at least the end of September. According to the organization, this would help reduce the drastic inequality in the distribution of vaccines between rich and poor countries.
“There is a political decision here, based on scientific data, on the reduction of antibody titers and the ability to neutralize to obtain the maximum effect in controlling the virus. Ethically, in what, let’s say, from a common human point of view, if we think globally, it is fair, it is another question ”, explained Marius Strioga, Doctor of Biomedical Sciences.
Lithuania did not wait for the producers’ conclusions and began revaccination based on Israel’s experience. In Israel, the number of infections despite booster vaccination is currently high, but the New England Journal of Medicine reports that a short-term study in Israel found that the number of confirmed infections was eleven times lower in the booster group. than in the group that received the booster dose and was vaccinated with only two doses.
Furthermore, severe cases were also twenty times less frequent with maintenance doses.
“Preliminary data from the Israeli Ministry of Health shows that by giving the third dose to previously vaccinated people over a period of time and comparing infections and symptomatic infections of those who received the third dose and not, the relative efficacy of the third dose it has finished 85% “, assured M. Strioga.
Experts speculate that the third dose of the vaccine is not the last to fight the coronavirus.
“We just realized that the fourth, perhaps the fifth, could be needed at increasingly greater intervals. It is quite likely, it is real and it will have to be done as I have said many times before bringing that virus to earth,” added the Doctor in Biomedical Sciences.
The good news is that a recent data analysis by the Department of Statistics has finally confirmed that the Pfizer vaccine is effective against the Delta strain. Vaccinated people are ten times less likely to get COVID-19 than unvaccinated people.
The virus is five times less likely to be infected, and the Pfizer vaccine reduces the chance of dying twenty times.
