– The H1N1 vaccine trials that were put on hold after a serious side effect in a volunteer in Britain have resumed in Britain and Brazil. Johnson & Johnson’s vaccine trials in Spain have also resumed, but some volunteers have dropped out, Reuters reports. “Many have called to ask us some more detail about the risk of the vaccine, whether what happened with that vaccine had anything to do with the one we are studying, these types of questions,” says the Spanish investigator for Johnson & Johnson’s vaccine. Meanwhile, Pfizer and BioNTech have asked the FDA to expand their H1N1 vaccine trials to 44,000 participants from 33,000. The trials will be more diverse than the current trials, which only involve healthy people. “In the third phase, we will include all types of people,” the Spanish investigator says. “It is necessary to include a certain number of hypertense patients, white patients, Asian patients.”
