Booster Covid shots significantly improve protection against Omicron: Studies

Covid-19 vaccines are standing up to the omicron variant, at least among people who received booster shots.

They are the first large US studies to look at vaccine protection against omicron, health officials said.

The papers echo previous research — including studies in Germany, South Africa and the UK — indicating available vaccines are less effective against omicron than earlier versions of the coronavirus, but also that boosters significantly improve protection.

The first study looked at hospitalizations and emergency room and urgent care center visits in 10 states, from August to this month.

It found vaccine effectiveness was best after three doses of the Pfizer or Moderna vaccines in preventing Covid-19-associated emergency department and urgent care visits. Protection dropped from 94% during the delta wave to 82% during the omicron wave. Protection from just two doses was lower, especially if six months had passed since the second dose.

The second study focused on Covid-19 case and death rates in 25 states from the beginning of April through Christmas. People who were boosted had the highest protection against coronavirus infection, both during the time delta was dominant and also when omicron was taking over.

Those two articles were published online by the Centers for Disease Control and Prevention.

The Journal of the American Medical Association published the third study, also led by CDC researchers. It looked at people who tested positive for Covid-19 from Dec. 10 to Jan. 1 at more than 4,600 testing sites across the US.

Three shots of the Pfizer and Moderna vaccines were about 67% effective against omicron-related symptomatic disease compared with unvaccinated people. Two doses, however, offered no

(Photos by: Photo 12/Universal Images Group AMSTERDAM - A cold case team that combed through evidence for five years in a bid to unravel one of World War II's enduring mysteries has reached what it calls the "most likely scenario" of who betrayed Jewish teenage diarist Anne Frank and her family.Their answer, outlined in a new book called "The Betrayal of Anne Frank A Cold Case Investigation," by Canadian academic and author Rosemary Sullivan, is that it could have been a prominent Jewish notary called Arnold van den Bergh, who disclosed the secret annex hiding place of the Frank family to German occupiers to save his own family from deportation and murder in Nazi concentration camps."We have investigated over 30 suspects in 20 different scenarios, leaving one scenario we like to refer to as the most likely scenario," said film maker Thijs Bayens, who had the idea to put together the cold case team, that was led by retired FBI agent Vincent Pankoke, to forensically examine the evidence.Bayens was quick to add that, "we don’t have 100% certainty.""There is no smoking gun because betrayal is circumstantial," Bayens told The Associated Press on Monday.The Franks and four other Jews hid in the annex, reached by a secret staircase hidden behind a bookcase, from July 1942 until they were discovered in August 1944 and deported to concentration camps.Only Anne’s father, Otto Frank, survived the war.
