Mosialos: Enough protection against Omicron with the three doses


The spread of the new Omicron variant of the coronavirus means that we must “take the third dose immediately because, as several studies show, we will have enough protection against the Omicron if we have done all three doses. Those who have not been vaccinated should think seriously. what they will do.

“The problem of our country is the relatively high percentage of unvaccinated (compared to other countries) over the age of 50. But those who have taken the third dose, should not have much cause for concern.” This points out in a new post on Facebook Professor of Health Policy Elias Mosialos of Imperial College and the London School of Economics and Political Science (LSE).

Referring to a new study from Imperial College, he said: that no difference was found between the two variants “. He adds that “the authors of the study point out in the discussion of the data they analyzed, that no evidence was found that the cases of micron had a different clinical picture (better or worse) than delta, based on the percentage of positively diagnosed who had symptoms or “At the moment, they do not have enough data on the clinical picture of the micron in relation to the delta.”

On the other hand, he points out that “data from South Africa show that there is a de-escalation of the pandemic wave in this country”, but “even there, we do not know if there is a delay in the official recording of cases, and therefore not a real de-escalation. “It happened a few days ago. And while the leadership of the South African Ministry of Health appears optimistic, I would say to wait a few more days to have a clearer picture.”

He stressed that “depending on the news published by the media, one can say that we have a big problem or that in fact the problem is temporary. But we do not know exactly yet. In Great Britain it is clear that we have a significant increase in cases. 93,000 people were diagnosed positive. Let’s say here that the percentage of cases that are admitted to the hospital and are stuck is not clear. “to the health system in the coming days. I would therefore recommend that we do not rush to conclusions.”

According to Mosialos, “Imperial’s study confirmed what we know about the contagion, but in fact nothing is clear about the severity of the infection. As I said, the South African data is encouraging, but there may be a delay problem. in the recording, and to interpret the micron wave there having data of delayed recording “.

He also points out that “the effects of one variant can have a different impact per country” and explains that in a country like South Africa with a small proportion of the elderly and vulnerable in the population, but at the same time a large proportion of the population with immunoprotection, another variant of the virus, or because many have been vaccinated, the effects will be small. On the other hand, the effects will be greater when immunoprotection in the population is low and we have a relatively large number of vulnerable citizens.

Greece is characterized by good but not very high vaccination coverage and at the same time by a high percentage of citizens in the high risk category. Also a higher rate of unvaccinated people over the age of 50, compared to other countries in Southern and Northern Europe. “Therefore”, according to him, “even if the micron is milder than the delta, the effects in Greece may be greater compared to Denmark or Portugal”.
