The protective effect may be improved if you receive a different quality of vaccine each time you receive the vaccine.
About coronary vaccinations In Finland, those who decide will consider whether there is a need to speed up the pace of vaccination this week, says Chief Medical Officer Hanna Nohynek from the Department of Health and Welfare. The European Medicines Agency (EMA) recently announced that states may consider a three-month vaccination interval, although the EMA’s official recommendation is six months between the second and third dose.
In Finland, the vaccination interval between the second and third peaks of the corona was recommended to be at least six months until the beginning of December.
“It’s about what we’re trying to prevent. The protective efficacy of the vaccine against severe coronary heart disease remains very good for at least six months, except in the very old and at-risk groups. In that sense, 5 to 6 months is a very good vaccination interval to prevent severe coronary heart disease. However, if you want to increase protection against omicron-borne transmission infections, which have so far been largely mild, then a three-month vaccination interval is possible, ”Nohynek compares.
At the same time, he reminds that there are now four million people in Finland who have received a second corona spike at least three months ago.
“There are not and will not be four million doses of vaccine in Finland in a short time. Here we have to look at what is logistically possible: what are the doses and the workforce of the vaccinators. ”
Although the recent omicron variant seems to be able to circumvent vaccine protection better than the previous delta variant, according to Nohynek, good news has also been obtained.
“The diseases caused by Omikron have been a mild form of the disease, at least according to preliminary data. Even two doses of the vaccine are likely to protect against a serious form of the disease. ”
According to Nohynek, recent research from Britain showed that none of the nearly 600 self-infections diagnosed had led to a serious illness that required hospitalization.
“According to that analysis, after the second dose of the vaccine, the protective effect was 20% against a mild infection. Thus, the protective effect against the mild illness caused by omicron was clearly reduced compared to that caused by the delta variant. However, after the third dose of the vaccine, protection against mild omicron infection also rose to 60-70%. ”
According to Nohynek, this raises the question of whether a separate omicron vaccine is absolutely necessary.
“Based on those results, even current vaccines provide significant protection against omicron.”
Nohynek too it is also important whether or not a person receives the same vaccine at each vaccination.
“Giving three coronary vaccinations each time with a different vaccine would seem to improve vaccination protection, especially when the first dose has been Astra Zeneca. The protective effect is improved by such cross-vaccination.
However, according to Nohynek, it seems that cross-vaccination may slightly increase short-term side effects.
“They seem to be the symptoms that are typical of the side effects of the last vaccine.”
In Finland, quite a number of people already received cross-vaccination due to the fact that some of those who received their first peak Astra Zeneca were transferred to Pfizer or Moderna for the second time.
