Judging by the words of head of the Ministry of Health Viktor Lyashko, said in an interview with Radio Liberty, no one can say anything more specifically about this so far.

Literally it sounds like this:

"Most likely what will happen. But it is not known, booster or re-double vaccination. This is a question for consideration. But we are not yet at the level of vaccination coverage of the adult population to talk about the introduction of a booster or booster vaccination. Today we are strictly following the WHO recommendations, which says that you must first ensure that as many adults as possible have access to at least one dose or full course of vaccination."

A week later, it became known that the National Technical Group of Experts on Immunoprophylaxis of Ukraine approved recommendations on revaccination against Covid or the introduction of a booster dose with an interval of six months after the second.

But first, let's dwell on the key issue.

What is a booster dose?

As the head of the aforementioned technical group of experts Fyodor Lapiy clarifies (in the commentary by RBC-Ukraine), in other words, this is revaccination. The booster dose is one. And it is usually given six months after the primary vaccine complex (two doses, like most current Covid-19 vaccines).

What is it for? To restore, strengthen, increase the protection that was received earlier.

Who is it recommended to?

Not everyone at the moment.

“As for the revaccination six months after the full course, we have not yet made a decision on the recommendation of universal revaccination for everyone. We have approved revaccination in six months for medical workers and nursing home workers,” Lapiy said.

Is the extra dose not a booster dose?

Lapiy clarifies that no.

According to him, the additional dose (that is, the third dose or the second for Johnson & Johnson) is not a booster or revaccinal. It is given to individuals who respond poorly to the initial course of vaccination.

These are immunocompromised individuals. For example, patients with cancer; patients who have serious immunity problems, immunodeficiencies; patients receiving drugs that suppress the immune response.

The additional dose will be given at least 28 days after the second dose.

Which countries are already getting their third coronavirus vaccine?

In Israel, elderly people and people with weak immunity are already receiving such vaccinations. As in the United States, where the third vaccination began in September for the elderly and vulnerable groups.

Similarly, residents of the Czech Republic, Italy, and Latvia can already receive the third vaccination. In Canada, the booster was allowed for people over the age of 18.

According to the head of Pfizer Albert Burla, it will probably be required to undergo revaccination against the coronavirus approximately every year.
