Medicine / Health, Illness | New study: Infection provides better protection than vaccine

Those who have been infected with coronary heart disease may be better protected against the delta variant of the virus than those who have received two doses of the Pfizer vaccine, according to a new study.

But it is still a bad idea to contract the infection on purpose, the researchers emphasize.

The study was conducted by Israeli researchers by comparing the immunity of the population using tens of thousands of journals.

It has not yet been published, but a pre-version has been posted on Medrxiv.

And the differences are huge. According to the researchers, there is a six to thirteen times greater risk of becoming infected with the delta variant if you have been vaccinated and previously uninfected than if you have had covid-19.

Israel opens for third dose to anyone over the age of twelve – NIPH follows closely

Israel opens for a third vaccine dose to anyone over the age of twelve in the fight against delta infection. NIPH says there are no sure grounds that it is necessary.

Israel was out early in the vaccination and is a country the world is watching closely to get answers about the effects of the vaccines. Now 20 percent have received the third dose.

Israeli authorities refer to preliminary findings that the third dose helps to suppress the delta wave and prevent serious illness.

The National Institute of Public Health states that they are closely following the situation in Israel.

– In our assessment, there are still no reliable indications that vaccine protection against disease is weakening so quickly that it is now necessary with a third dose in Norway, says chief physician Preben Aavitsland at the National Institute of Public Health (NIPH) to NTB.

Recommend if needed

He says the evidence for this must be in the form of data from the population and that NIPH has not yet seen it.

– Israel has since the beginning been first in the vaccination course. The whole world now follows their experiences very closely, says Aavitsland.

The Israeli prime minister says the evidence is there.

– The third dose works. There are already results, he writes Twitter.

The Israeli Ministry of Health states that the third dose increases the protection against serious illness to 97 percent, according to the Times of Israel. Researchers at Hebrew University believe they can show that the third dose prevented the spread of infection in a delta wave, writes Haaretz.

Aavitsland says FHI will recommend a third dose if they see the need for it, whether it is this year, next year, 2025 or 2030.

After Israel was able to open up society earlier this year after a rapid vaccination, the delta variant has created problems this summer. The infection is now high also among those vaccinated, and measures have been introduced such as bandages and restrictions on how many can be collected.

Passing Israel

Aavitsland points out that Israel has only given 68 percent of the population one dose, while 62 percent are fully vaccinated. In Norway, the figures are 71 per cent with at least one dose and 56 per cent fully vaccinated.

– So we will get greater vaccination coverage with two doses than Israel has, says Aavitsland.

This summer, Israel decided to offer everyone over the age of 60 a third dose of coronary vaccine, and since then this has been gradually expanded to apply to younger groups.

Israeli experts say the effectiveness of the vaccines is gradually diminishing, and recommend a third dose five months after people have been vaccinated for the first time.
