What fall are you waiting for?
Vytautas Usonis, a professor in the Department of Pediatrics, told the show that we must prepare for the upcoming fall season.
“It is really worrying that in the summer, when the coronavirus activity is expected to be lower, we will have an increase in the number of cases. And this raises a very simple question: what will happen in November and December? The professor asked.
V. Usonis said that there is a very high probability that the situation will be exactly the same as in December last year.
“It just came to our knowledge then. The only difference should be how we will be prepared. Last year, we had no other means than to control the routes of spread: quarantine, masks, barriers, disinfection. And this year we already have a very weapon. powerful: a vaccine. This year it is already possible to start calculating the public immunity index “, explained the professor.
Vaccines for coronavirus
The interlocutor of the informative radio program “Question of the day” assured that the doses of vaccine stored in the warehouses must be used in a rational way so that they do not have to be destroyed.
“To protect our people as best as possible,” explained Professor V. Usonis.
Virologist Saulius Čaplinskas said even more strictly: there are no preconditions for thinking that next fall and winter will be different from last year.
“I don’t want to repeat negative predictions and things like that. But unfortunately, the situation is like that,” said S. Čaplinskas.
V. Usonis also raised the question of whether our social communication should be as intense as it was before the pandemic.
When is it worth vaccinating with 3 doses of vaccine?
Professor V. Usonis explained that after the full vaccination schedule, another dose should not be called the third vaccine at all.
“I would not call it the third vaccine. There are classics, we still remember the textbooks, dead vaccines are vaccinated in several stages. The first vaccination with one, two or three doses triggers a primary immune response. Calm, provides protection for more or more less time. But dead vaccines do not multiply in the vaccinated person. Therefore, after a while it is necessary to inject a booster dose “, explained the expert.
He said a booster dose would be given after the initial immune response.
“Sooner or later, a booster dose will be needed,” V. Usonis said on Tuesday’s “Question of the Day” radio news program.
When asked when a booster dose of the vaccine is needed, the professor said the answer is very clear.
“That answer came from the measles vaccine. The great contribution of Finnish scientists was made several decades ago. It is not necessary to wait in the immunological sense for the antibodies to disappear completely, it is not necessary to wait for the immunity to disappear completely and for the protection to completely disappear. Let’s say the same measles vaccine is vaccinated in Lithuania for the first time in the second year of life. And the second, the booster dose is vaccinated before school, “explained V. Usonis.

He said there was no need to wait for the protection to completely fade.
Therefore, research is being done to see what protection is. Do people still have antibodies? Most importantly, vaccinated people don’t get sick because it’s not just the antibodies that provide protection. And all this is done so that we know as precisely as possible when that dose of strengthening is already necessary, ”said V. Usonis.
Virologist Saulius Čaplinskas told the show that it is still difficult to talk about the third vaccine and the problems of receiving vaccines in other countries.
“When it comes to attending webinars, specialists and virologists have no doubt that the time will come when that third dose will be needed. Only now it is not possible to establish a clear criterion of when a third person would need a third. vaccine, those booster doses of the vaccine. And the main reason is social and geopolitical. Lithuania, Israel, the European Union can afford that third dose of the vaccine, but most of the countries of the world still have a minority of their population receiving the first vaccine, “he explained.
S. Čaplinskas, interlocutor of the radio news program “Question of the day”, explained that a large mass of susceptible people is necessary for the high spread and mutation of the virus.
“And because of that, the virus mutates rapidly: when a person is infected from one person quickly, when there are many susceptible people, without the vaccine, the virus not only spreads, but also mutates,” said virologist S Čaplinskas on the radio news program “Question of the Day”.

“This can happen in people who have been vaccinated or become ill if their immunity weakens,” explained the expert.
Some experts call for a third dose of the vaccine to be planned in the near future. According to virologist S. Čaplinskas, 3 doses of the vaccine should be given without delay to people at increased risk of severe disease.
“The answer would be that today – because it is clear that after 76 days the immunity has already begun to fade, only that in each case it happens individually. And, for example, children have the immune system that works best, and those who, over the years, such as the elderly, have weakened immunity. Immunity is also weakened in those who suffer from chronic diseases that weaken immunity. Here would be the answer, guidance is needed according to this criterion. It is now known that even after getting sick, vaccinating people with the delta strain can get sick much faster.
And the infected delta strain, even vaccinated people, secrete enough virus. It means that they become contagious.
So now that we have the vaccines and even some of them are being thrown away, it is worth those people who are, say, half a year after vaccination and who are most at risk: older people with diseases and doctors, social workers, nursing staff. solution ”, – virologist S. Čaplinskas spoke on the radio news program“ Question of the day ”.
V. Usonis also agreed with this position.
“What matters is not the maximum time in which the vaccine can be administered at the latest, but the minimum time in which it can be administered before. And the earliest period is about 3 months, after the disease or after of the initial vaccination, “explained Professor V. Usonis.
