Pfizer said its combination vaccine candidates targeting Covid and the flu will move to a final-stage trial in the coming months after showing positive initial results. ..
Pfizer and other vaccine makers like Moderna and Novavax believe combination shots will simplify the process for people to protect themselves against respiratory viruses that typically surge around the same time of the year.
In a press release, the biopharmaceutical company said the combination vaccine has "the potential to efficiently reduce the overall burden of acute viral respiratory disease" by giving simultaneous protection against flu and COVID in a single dose.
Children who tested positive for COVID-19 in 2022 were contagious for a median of 3 days, regardless of vaccination status, suggesting that 5-day school isolation policies are sufficient amid Omicron variant predominance, University of Southern California (USC) and Stanford University researchers report today in JAMA Pediatrics.
