Washington (AFP) - Pfizer and BioNTech have asked United States health officials to authorize their Omicron-targeting Covid booster vaccine for children aged 5 to 11, the companies said Monday. The companies sent a request for emergency authorization for a 10-microgram dose to the US Food and Drug Administration. This new generation of anti-Covid vaccines targets both the original strain of coronavirus and the BA.4 and BA.5 lineages, the subvariants of Omicron that are causing more than 90% of infections in the United States. If the FDA authorizes the vaccine, the shot will still need another...

Washington (AFP) - Barring the emergence of drastically different variants, Covid boosters will likely be recommended annually in a similar manner to influenza vaccines, US health officials said Tuesday. The announcement came after the Food and Drug Administration last week authorized updated bivalent shots against both the original strain of the coronavirus and the BA.4 and BA.5 lineages of the Omicron variant, which are predominant. "We likely are moving towards a path with a vaccination cadence similar to that of the annual influenza vaccine, with annual updated Covid-19 shots matched to th...

Washington (AFP) - Covid-19 vaccines and boosters continued to have very high efficacy against severe outcomes during the Omicron wave of the virus, a large real-world study from the US Centers for Disease Control and Prevention (CDC) showed Friday. The paper evaluated data from more than 300,000 visits to emergency departments, urgent care clinics, and hospitalizations across 10 states from August 26, 2021 to January 5, 2022. During the period when the Delta variant was dominant, vaccine efficacy against Covid-19 hospitalization was 90 percent between 14-179 days after dose two of a vaccine, ...

Washington (AFP) - A preliminary US study of nearly 70,000 Covid positive people showed a substantially reduced risk of hospitalization and death from Omicron even after controlling for growing population immunity levels. People infected with Omicron were half as likely to be hospitalized, about 75 percent less likely to need intensive care, and around 90 percent less likely to die compared to those infected with the formerly dominant Delta variant, according to the paper. Of some 52,000 people infected with Omicron, none ended up on a ventilator, compared to 11 people from nearly 17,000 with ...

Washington (AFP) - The United States on Wednesday announced its first confirmed case of the Covid-19 Omicron variant had been detected in California, in a fully vaccinated traveler who had recently returned from South Africa and was recovering from mild symptoms. Top health official Anthony Fauci said authorities "knew it was just a matter of time" before the strain was found in the country, reminding Americans that vaccination, boosters and masking in indoor public settings remained the best way to stay protected. According to a statement by the Centers for Disease Control and Prevention (CDC...

Washington (AFP) - President Joe Biden on Monday told Americans not to "panic" over the newly identified Covid variant Omicron and said he does not foresee new lockdowns or extending travel restrictions for now. The virus variant, first detected in South Africa but already appearing in multiple countries, "is a cause for concern, not a cause for panic," Biden said. He stressed that the United States was in a good position to control Omicron's spread without having to resort to lockdowns or more travel bans beyond restrictions already imposed on eight southern African countries. "We have more t...
