A new, more contagious variant of coronavirus first seen in the UK is likely to fuel a surge of cases in the US in spring, several experts predicted Tuesday. They say the best way to get out ahead of it is to vaccinate as many people as possible.
The variant called B.1.1.7 was suspected of causing renewed spread in Britain and it’s been seen across much of the US – more than 1,880 cases in 45 states, according to the US Centers for Disease Control and Prevention. But those are only the cases detected by sequencing, which falls short in the US, said virus expert Trevor Bedford of the University of Washington and the Fred Hutchinson Cancer Research Center.

Recipients describe symptoms from fever to fatigue that are more profound than the jolt some get from a seasonal flu shot. Although the post-vaccination malaise is generally innocuous and fades after a day or two, some hospitals and medical centers are staggering immunizations of health workers to avoid a brief cluster of absenteei

All we understand now is how well they prevent people from becoming significantly sick.
The ability of the vaccines to prevent all infections may seem like an arcane topic compared to their proven ability to stave off moderate-to-severe illness and death. Still, infection prevention is going to be one of the determinants about how many people die. In effect, you have to vaccinate fewer people to get to herd immunity with a vaccine that protects against infection, Joshua Schiffer, MD, MSc, of Fred Hutchinson Cancer Research Center, told
