Here's why you probably won't need a booster shot against the delta variant anytime soon
Facing the threat of a more infectious Delta variant, vaccine makers Pfizer and BioNTech released a statement on Thursday saying it "may be beneficial" for people to get a third dose of their COVID vaccine within six months to a year. But U.S. health officials and other scientists have vehemently disagreed, saying our current vaccines are holding up really well – at least so far. As viral diseases go, COVID-19 is "a slow burn," said Deepta Bhattacharya, an immunologist at the University of Arizona. In its early days, when it is most contagious, people experience cold symptoms or no symptoms at all. In serious cases, after about a week, people can go on to develop dangerous lung infections, caused by our immune systems going haywire and attacking vital organs.
