Coronavirus: Who and when will need a fourth dose of the vaccine

by

The decisions for the administration of the fourth installment are expected in April vaccine in the elderly and people at high risk for serious illness in our country, according to a publication of Everyday.

For the rest of the population, a possible scenario, and always depending on the developments in the development of new versions of the vaccine, is that next September there will be recommendations for a new vaccination cycle that will provide wider coverage against “Omicron”.

The National Vaccination Committee monitors all data collected, as well as analyzes of the effectiveness of the fourth dose in people who, due to age or health problems, are at high risk for serious illness, in order to decide when a fourth dose can be given to which population groups.

According to the professor of Pediatrics of EKPA and member of the Committee, Vana Papaevangelou, it will take at least another two weeks in order to make decisions on this issue.

In fact, the decision will be influenced by the position of the FDA, which has been called to consider Pfizer’s application for approval of the fourth installment for people over 65 years of age.

According to Evangelos Manolopoulos, Professor of Pharmacology at the Democritus University of Thrace, Pfizer bases its application on data from Israel, where the fourth dose is given to people over 60 years of age and to medical staff. According to these data, the fourth dose restores the level of antibodies achieved with the third dose and reduces the chance of infection with the virus.

“In our country, the administration from the age of 60 and over can be considered. In fact, it seems that the decisions will coincide with a further relaxation of the measures that are in force now to prevent the spread of the virus “, Mr. Manolopoulos emphasizes and adds that this decision may be extended to people with chronic diseases and high risk of serious illness regardless of age.

Asked when the rest of the population will be called to be vaccinated again, the professor of Pharmacology points out that “everything contributes to the fact that we should prevent it next autumn, when the next outbreak of Covid-19 is expected. However, the prevailing scenario, if the pandemic continues as it is today and a new strain does not appear with completely different characteristics that will overturn the plans, is towards the end of summer with the beginning of autumn we are all called to be vaccinated with an improved version of the vaccine which will have a wider range of protection and will cover known variants. We will not talk about a fourth dose, but about a new vaccination cycle or an annual vaccination “.
