The president of the American pharmaceutical concern informed that "probably" the vaccination against COVID-19 will have to be supplemented with the third dose of the preparation within 12 months. We asked an expert if this scenario could come true!
There is speculation in the United States that citizens may need to be vaccinated with an additional dose of COVID-19.This would occur within a year of fully vaccinating . There is currently an ongoing study of how long immunity may last as a result of receiving the SARS-CoV-2 vaccine. David Kessler, the US government's plenipotentiary for combating COVID-19, said a third dose of the coronavirus vaccine may be needed.
Albert Bourla, CEO of pharmaceutical company Pfizer, commented on these speculations. According to him"maybe" the third dose of the so-called You will need a booster to complete theimmunization. It would then be administered within (6-12 months) from the moment of taking two doses of the preparation. Albert Bourl also does not rule out that COVID-19 vaccinations may have to be vaccinated every year. As he emphasized, different variants of the coronavirus must be taken into account. For now, these are only assumptions and possible scenarios that may occur in the future.
Whether it would be necessary to administer a third dose of the SARS-CoV-2 vaccine was also discussed in Poland. Deputy Minister of He alth, Waldemar Kraska, stated that "perhaps there will be a situation where this vaccine will have to be repeated" of those who were vaccinated at the beginning of the year. As he emphasized,the coronavirus mutates and perhaps "this vaccine will have to be modified in some way" .
The expert dispels doubts
We asked an expert if a third dose of the coronavirus preparation would be necessary. Virologistprof. dr hab. Krzysztof Pyrć from the Lesser Poland Biotechnology Center of the Jagiellonian Universitynoted that " it is not known yet how long after the COVID-19 vaccine" immunity will last. " infections in vaccinated people, when we see that the levels of antibodies in the vaccinated people drop, we will then know that this effectiveness is maintained for a certain period of time. At the moment we knowthat the immunity remains at a high level - the expert explained in an interview with our website serwisnikzdrowie.pl.
As added by prof. dr hab. Krzysztof Pyrć,"The literature shows that the risk of infection in convalescents is reduced by about 80%" . - Vaccines seem to be more effective. It can be expected that this protection will last much longer - maybe 2-3 years. However, we must check it empirically. When it turns out that the level of immunity is declining or variants that successfully evade our defense system appear, you will need to consider giving a booster dose. A similar situation is e.g. in the case of jaundice type B. When the level of antibodies decreases, it is necessary to vaccinate. - he said.
According to the virologist, " if a booster dose is required, it won't be surprising or particularly scary." . - It will be more terrifying for me if the pandemic does not end, because we will be scared of vaccinations - he said.
