The oncologist spoke about it on Tuesday on the “Delfi rytas” program. Speaking about the duration of the AstraZeneca vaccine between the first and second doses, Mr. Strioga noted that it could be shortened for good reason.
“If there are good reasons for this, then yes, that interval can be shortened; let’s say the second dose coincides with the graduate exam session or requires an exit and requires a full vaccination plan before,” said the doctor.
He explained why it was decided to vaccinate with a second dose of AstraZeneca only after 12 weeks. According to M. Strioga, such efficiency of the term is supported by research conducted by scientists.
“The results show that the protection is 76% 3-4 weeks after the first dose of the vaccine. If a second dose of the vaccine is given 12 weeks after vaccination, that effectiveness increases to 82%. However, the strange and more difficult thing to explain immunologically is that if the second dose is injected before 6 weeks later, the effectiveness drops from 76 to 54 percent. On this basis, it was justified that it would be better if the interval between doses was longer ”, explained the oncologist.
Therefore, Mr Strioga pointed out, the 12-week deadline must continue to be met.

“It is rational that delaying the second dose by 12 weeks is justified and that the efficacy is not lost during that period and increases even after the second dose. I think this should be followed, “said the doctor.
On Monday, data scientist Vaidotas Zemlys-Balevičius suggested on the Delfi rytas program that he refrain from vaccinating with a second dose so that as many people as possible could be vaccinated with at least one dose of the vaccine. Strioga supported this idea.
“If we differentiate one dose and postpone the application of the second dose, then until July 1, when a large number of doses of vaccine are already expected and mass vaccination will begin, 300-500 thousand. more people get vaccinated and have already vaccinated at least 50 percent. all populations.
That validity is indeed, especially since there is no evidence from the immune side against it. (…) I also share this point of view. Although a little lower, the partial protection after the first dose should guarantee better control of the spread of the virus in society, ”noted the doctor.
Vaccines for COVID-19
Speaking about the planned implementation of a passport in the country, Strioga said that a negative result of a coronavirus test could be an integral part of such a document, but for the moment, such a response should be short-lived.
“The tests must be frequent enough, especially in the current epidemiological situation. In my head, the test could be valid for 24, 36 hours. Later, as the epidemiological situation improves, it is conceivable that that test could validate that passport for 48 or even 72 hours. (…) This day should be 24, 36 hours after taking the test. Not because of the result, but because of the test, “added the oncologist.
