Biden’s new Covid-19 vaccination goal won’t get the US to herd immunity before the fall

President Joe Biden on Monday raised his Covid-19 vaccination goal to 1.5 million shots a day, up from 100 million in his first 100 days (or 1 million a day), following criticism that the previous goal wasn’t ambitious enough.

Even before Biden took office last Wednesday, his previous goal looked like a done deal — with the country averaging around 900,000 shots a day. Then, over the weekend, the US surpassed 1 million shots a day, before Biden’s policies and executive actions had any time to really sink in.

Even 1.5 million a day, which is enough to fully vaccinate 750,000 Americans with the two-shot vaccines, might not be fast enough for many experts’ goal to complete the bulk of the vaccine campaign by or in the summer.

According to experts, about 70 to 80 percent of the country, and possibly more, must be vaccinated to reach herd immunity and sufficient population protection. That means 245 million Americans likely have to be vaccinated, with 19 million already getting at least their first doses.

At a rate of 1 million shots a day, the US may not hit herd immunity until as late as next year. At 1.5 million, the campaign could drag into the fall and possibly winter.
