Sweden recommends 4th COVID-19 shot for certain groups

On February 14, Swedish authorities need to take a fourth COVID-19 shot as protection against the CCP (Chinese Communist Party) virus that causes COVID-19 is weakening for all people over the age of 80. Said.

According to the Swedish Public Health Service, in addition to everyone over the age of 80, anyone living in a nursing home or helping a life supporter visiting a home should have a fourth shot or a second booster. You need to get it.

The second booster will be available 4 months after receiving the first booster.

Recommended for those who have been vaccinated with the Moderna or Pfizer-BioNTech vaccine.

Both are built on messenger RNA (mRNA) technology and are usually given in a two-dose primary regimen, with the first dosing every few weeks.

Primary regimens have proven to be inadequate for adequate protection from infection, and protection against hospitalization is significantly reduced over time, especially following the emergence of Omicron CCP virus variants. did.

That has led to booster recommendations by health agencies around the world.

“The increase in vaccinations over the last few weeks is attributed to the fact that the vaccine after two doses is less effective against infection with the Omicron mutant compared to the Delta mutant,” said Swedish Health. The agency states on its website.

Omicron virus variants replaced Delta in late 2021 in Sweden and many other countries.

“Many of the vaccinated cases have been vaccinated twice but have not yet had time to supplement the third,” the agency says.

Studies in Israel, the United States, and other countries show that the first boosters enhance the reduced defense against infections and severe illnesses, but in the weeks and months after the boosters people have new defenses. Experience a decline.

“The finding that the protection provided by the mRNA vaccine diminished months after receiving the third vaccine was to maintain or improve protection against COVID-19-related ED / UC encounters and COVID-19 hospitalization. Further strengthening the importance of further consideration of additional doses. Researchers at the US Center for Disease Control and Prevention and other US institutions wrote in a study published on February 11. ED stands for Emergency Department. , UC stands for emergency treatment.

Anders Tegnell, chief epidemiologist in Sweden, said that four doses of one of the mRNA jabs “strengthen protection” against infection, serious illness, and death.

Sweden has already recommended that all adults over the age of 18 take a third shot of a Moderna or Pfizer shot, offering a fourth shot to some people with a weakened immune system. ..

Other countries have previously expanded the number of people eligible for a fourth dose of one of the vaccines. Israel, one of the most vaccinated countries in the world, was the second in January to all adults over the age of 60 with serious underlying illness, in addition to those who care for their population. He said he could get a booster. South Korea said on Monday that people living in nursing homes and similar facilities will be able to get a fourth shot.
