As the virus spread around the world, it turned into more contagious strains, including alpha and delta types. While vaccines have been shown to be effective against these variants, experts warn that it is important to progress beyond them with a wide range of vaccines.
If the virus continues to spread, it has the potential to create even more infectious variants, Afid said.
“When a virus is highly contagious, if you are going to stop it from spreading, you need to have a large population that is protected and immune,” he said.
According to Aphid in the winter, when the virus re-emerges, the United States should get 80% or more of the vaccinated population to protect the population.
The good news is that, despite the fact that the spread of most infections is less prevented by vaccines, the level of protection is still high.
“I think the vaccines will get you out of the hospital, keep you out of the ICU, and prevent you from dying,” Affid said.
The study suggests that the immune system protection may be extended up to a year after infection
The researchers said that B-cells in the human immune system build up defenses against Covit-19 for at least a year.
Studies show that survivors of corona virus infections may be exposed to newer strains of the virus, but vaccines, especially those made by Pfizer / Bioentech and MRNA vaccines made by Moderna, are developing a strong response to protect people against those strains.
Researchers also say that cats need to be included in any precautionary measures against the virus.
“Data show that immunity in active individuals lasts a very long time, and that individuals who receive the available MRNA vaccine develop antibodies and memory B cells that protect them from circulating SARS-CoV-2.
“Antibodies produced by memory cells produce increased width and energy,” said Michael Nusensweek, a molecular immunologist at The Rockefeller University who worked on the study.
Nusensweek said research should encourage people who have previously had Covit-19 to already be vaccinated. “Yes, they should be vaccinated,” he said. “If they do, they should be bomb-proof for SARS-CoV-2.”
The first state that was completely closed reopens
California was the first state to issue a home stay order regarding corona virus concerns. Now, 15 months later, it is reopening.
As of Tuesday, capacity limits and social distance requirements for all businesses will be removed. There will be some more restrictions on large events such as concerts, conferences and sports, including vaccination verification requirements for those attending indoor events with 5,000 or more and recommendations for outdoor events with more than 10,000 participants.
California has provided nearly 40 million vaccines, and at least 72% of the state’s population has been vaccinated to some extent, state Gov. Newsom said Monday. About 47% of the state’s population is fully vaccinated.
The so-called vaccine passport will not be available, but Newsom plans to announce an electronic version of the state’s vaccination cards this weekend.
California has invested $ 116.5 million in incentives, offering gift cards and cash prizes. On Tuesday, state officials will hold a map where 10 people who have been vaccinated will receive a grand prize of $ 1.5 million each.
Individuals who do not know how to wear a mask in indoor public settings will still be needed, but those who have been vaccinated can go without a mask in most situations.
Masks will be mandatory in some areas, including public transport and interiors in hospitals and prisons.
Businesses may need masks of their choice, and Call / OSHA is set to adhere to the new rules for covering the face in the workplace, but Newsom pointed out that it will sign an executive order this weekend as it is not expected until the end of June “to clear any ambiguity.”
