The COVID-19 vaccines are on track for a big recipe change this fall.
By LAURAN NEERGAARD and MIKE STOBBE Today’s vaccines still contain the original coronavirus strain, the one that started the pandemic — even though that was long ago supplanted by mutated versions as the virus rapidly evolves.
While infections have declined, the virus could be a real concern next winter, FDA’s vaccine chief Dr. Peter Marks said as the daylong meeting began. And while the FDA did allow seniors and others at high risk to get an extra booster dose this spring, most people will be many months beyond their last shot by fall.
So the FDA is leaning toward picking a fall shot recipe that targets just XBB. The hope is that the XBB variants are different enough to spark the immune system to make more diverse, cross-protective virus-fighting antibodies.
