Coronavirus and Vaccinations. Sick people vaccinated. How is this possible? And what’s the scale?

The fourth coronavirus wave in Poland he does not let go. According to Adam Niedzielski’s peak of disease is still ahead of us. One scenario predicts that the epidemic will reach its peak in the next week. Then you should expect an average of 25 thousand. cases per day. According to the second scenario, we will reach the peak in early December, and the daily number of new infections will reach 30-35 thousand.

Unvaccinated people dominate among those suffering from COVID-19. However, there are also those who, despite receiving the full dose of the vaccine, are also struggling with the coronavirus. One such person is 30-year-old Szymon Żyśko from Krakow, who fell ill four months after taking the second dose. – I had full flu symptoms plus back pain in the lumbar region. The doctor said it was the flu. Then there was a fever that was not affected by anything but ibuprofen. She relapsed for several days. There was a loss of smell after three days. I didn’t have a runny nose, but a swollen nose – says Interia.

– After all, I felt weak for a long time, I also had a dry cough – adds our interlocutor.

It turns out that coronavirus infection in fully vaccinated people is no surprise to virologists.

– In case of Delta variant data from the UK Public Health Institute and many other sources show that protection against severe disease after full immunization still persists above 90 percent for each of the approved vaccines. However, it should be remembered that this protection decreases over time, which may have a tragic end in the elderly. That is why we recommended the third dose, which restores immunity to a high level and hopefully will keep it for a long time – explains Interia, prof. Krzysztof Pyrć, virologist and member of the Medical Council at the premiere.

The situation is also related to prof. Agnieszka Szuster-Ciesielska from the Department of Virology and Immunology, Institute of Biological Sciences, Maria Curie-Skłodowska University in Lublin, which emphasizes that coronavirus infections, i.e. breakthrough infections in fully vaccinated people, occur most often in seniors over 60 years of age. As an immunologist and virologist, I can explain this by weaker immune responses in patients of this age. In addition, the elderly are usually burdened with diseases, which also weakens their immunity – says Prof. Szuster-Ciesielska.

Prof. Szuster-Ciesielska draws attention to another issue that may shed light on infections that appear in the elderly despite full vaccination. – They were vaccinated first together with the medics, which means that six or seven months have passed since they were vaccinated. As you know, after this time the effectiveness of the vaccine decreases. The solution is taking a booster dose, its effectiveness is evidenced by the fact that thanks to it, the next wave of COVID-19 has been completely brought under control in Israel and at the moment there are only incidental deaths and breakthrough infections – explains Prof. Szuster-Ciesielska.

Prof. Pyrć notes, in turn, that in younger people, protection against severe illness and death lasts longer, but protection against infection decreases.

– After receiving the mRNA vaccine, protection against infection remains at the level of about 50 percent even after many months, but for a single-dose vaccine it decreases faster – says Prof. Throw.

Due to the probability of infection of the vaccinated person, is the provision not to quarantine them after contact with a sick person still relevant? According to prof. Szuster-Ciesielska – it is not.

Transmission of the virus in vaccinated persons takes place, but it is not true, as the anti-vaccine groups say, that it is as effective as in unvaccinated persons. The virus load can be high in the first few days, but it goes down very quickly. Nevertheless, we can become infected from a vaccinated person who is sick, so in my opinion the vaccinated should also be sent to quarantine – says prof. Szuster-Ciesielska.

Prof. Pyrć, who believes that the vaccinated are safer, and thus do not have to be quarantined after contact with the sick. – If a vaccinated person becomes infected with the coronavirus, in most cases the disease will be shorter and the symptoms less intense. Statistically speaking, the vaccinated are “safer”, so they are not quarantined at this stage when they come into contact with the sick person. With confirmed infection, however, they should absolutely be isolated, just like the unvaccinated. Remember that vaccination is not a magic shield and we should not reject the principles of DDM at this stage – he says.

Notes that some steps are, however, needed to help tackle the fourth wave of the pandemic. – Considering the fact that several hundred people die every day, it would be appropriate to do something. Especially that winter has not even started yet. In my opinion, places and situations where the risk of infection is highest should be selected and the unvaccinated should be excluded from them. We should also remember that if we have a close relative who is not vaccinated – let’s try to convince him or her. He may simply not survive this winter – warns prof. Throw.

As reported by Ministry of Health, from January 27 this year (i.e. from the date when the administration of the second dose of the COVID-19 vaccine was started), vaccinated people accounted for only about 3 percent. deaths from COVID-19. They are predominantly people with multiple diseases, i.e. at least two other diseases.

The number of deaths among the vaccinated (after 14 days from the full dose) in Poland is 1996. This is the data of the Ministry of Health as of November 19, 2021.

On Monday, November 22, it was reported that 11,123 vaccinations against COVID-19 had been carried out in the last 24 hours.

20,268,848 Poles are fully vaccinated. 293,156 people received a third dose of the vaccine and a booster dose was 1,733,436 people.

The Ministry of Health reminds that, according to the position of the World Health Organization, building up immunity after vaccination usually takes several weeks, therefore it is possible that a person who has received the vaccine will be infected because they have not yet developed a sufficiently strong immune system response in case of exposure to SARS-CoV-2 virus. Therefore, regardless of the receipt of the vaccine, the sanitary regime should be followed. It is also possible that the person who was vaccinated became infected shortly before taking the vaccine and that symptoms did not develop until after the vaccination. According to information published by the Center for Disease Prevention and Control (CDC), the median time of onset of COVID-19 symptoms is four to five days from exposure to the SARS-CoV-2 virus.
