For the past week, the average number of Covid-19 deaths each day was 343, according to Johns Hopkins data on Monday.
Vaccines have been shown to be effective against these variants, but experts warn that it is important to get vaccinated as soon as possible.
“When a virus is more contagious, a higher percentage of the population will need to be protected and vaccinated if you are to stop the spread,” said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital in Philadelphia.
“We will need a highly vaccinated population for years, if not longer. This virus will circulate in the world for a long time.”
The longer a virus spreads, the greater the chance of producing even more contagious variants, Offit said.
The good news: While vaccines may be less inhibited from spreading more contagious variants, levels of protection still appear to be high, Offit said.
“I think vaccines will keep you out of the hospital, keep you out of the intensive care unit and keep you from dying,” he said.
Those who had Covid-19 should get vaccinated to be “bulletproof,” the researcher says
Researchers reported that the human immune system’s memory B cells offer protection against Covid-19 for at least a year.
Studies have shown that people who have recovered from coronavirus infection can be susceptible to new variants of the virus. But vaccines, especially mRNA vaccines such as those made by Pfizer / BioNTech and Moderna, create a powerful response that protects people from these variants.
An extra boost with a vaccine could expand the protection recovered patients have, researchers said.
“The data suggest that convalescent individuals have long-term immunity and that convalescent individuals receiving available mRNA vaccines produce antibodies and memory B cells that should protect against circulating SARS-CoV-2 variants.” wrote the researchers.
“The antibodies produced by the memory cells developed an increased breadth and effectiveness,” said the molecular immunologist Michel Nussenzweig of Rockefeller University, who worked on the study.
Nussenzweig said the research should encourage people who previously had Covid-19 to get vaccinated if they haven’t already. “Yes, they should get vaccinated,” he said. “And if they do, they should be bulletproof for SARS-CoV-2.”
The first fully shut down state will reopen
California was the first state to issue a home stay order during the pandemic. Now, 15 months later, it is fully reopening.
Starting Tuesday, capacity limits and social distancing requirements will be lifted for all businesses.
Some restrictions still apply to major events such as concerts, conventions, and sports – including vaccine verification requirements for attendees at indoor events with 5,000 or more people and recommendations for outdoor events with more than 10,000 attendees.
About 72% of Californians are at least partially vaccinated and about 47% of the state’s residents are fully vaccinated, Governor Gavin Newsom said Monday.
California has invested $ 116.5 million in vaccination incentives, including gift cards and cash prizes. On Tuesday, state officials are holding a drawing in which 10 vaccinated Californians will each win $ 1.5 million in prize money.
Fully vaccinated people can do without a mask in most situations, but those who are not vaccinated must continue to wear masks in indoor public places.
And in certain places, masks are prescribed for everyone, including on public transport, in hospitals and in prisons.
Businesses may require masks at their own discretion, and Cal / OSHA will be introducing new rules for face coverings in the workplace.
As this is not expected before the end of June, Newsom announced that it would sign an executive order later this week “to clear up ambiguities”.
